Generators for Boats: What to Look For? Wareham, MA

Joseph Coupal - Monday, April 24, 2017
South Shore Generator - Kohler Marine Generator

INVERTER OR GENERATOR?

Inverters change the DC power of the boat's batteries into AC power. They're compact and quiet but limited in output by the size of your bank of batteries and by the alternator's ability to keep up with the draw. Battery capacity should be at least three times the expected need between charges. Use inverters for short-term items such as coffeemakers and microwaves. Boats without air conditioning and loads in the 1,000-to-3,500-watt range can get by with inverters. However, for greater and longer power demands you will need a generator.

INVERTER/GENERATOR SYSTEMS

Save money by combining an inverter with a generator. When demands are low, use the inverter. When demands are high-such as when using air conditioning, freezers, and dishwashers-switch to the generator. You may be able to get by with a smaller, less expensive generator.

GAS OR DIESEL?

Match the generator's fuel needs with those of your main engines so you won't need a separate tank, necessitating extra trips to the fuel dock. Diesel is more expensive than gas but also more efficient. If you're buying a gas generator, it must be spark-free to avoid explosions. Also, you'll need to install extra cabin CO alarms.

ENGINE TYPE

Two-cylinder engines tend to vibrate. Four cylinder engines need to be counter-balanced to reduce vibrations. Three- and six-cylinder engines are naturally balanced and run smoothest.

RUNNING RPM

A generator will come to its designed voltage and frequency-60Hz in the United States and Canada-at a preset speed. For most generators, this will be at either 1200, 1800, or 3600 rpm. The 1200 models are large and heavy, and rarely used on pleasure craft. The 1800-rpm models are the most common. They're inexpensive, fuel efficient, quiet, and dependable. A 3600-rpm model might provide more power in a smaller and lighter package, but its high-revving design increases noise and decreases longevity. Consider adding the manufacturer's sound enclosures to minimize sound levels with a 3600-rpm unit.

ENGINE OR HYDRAULIC DRIVE

Hydraulic-drive generators are powered by a hydraulic pump on the main engine. The engine must be running to produce electricity. They're less expensive than self-powered models but are only suited to boats with intermittent power requirements or long-range cruisers that are under power most of the time.

OUTPUT

A generator that is too small will consistently trip breakers, wear out quicker, and possibly damage your electrical equipment. Too large a generator can also operate inefficiently, resulting in carbon buildup on the cylinder heads, and leaving unburned fuel in the exhaust. Never run with a load of 25 percent or less of the generator's output. From 40 to 75 percent is ideal.

ESTIMATING LOAD

List all the wattage requirements of the appliances on your boat. Figure you need the maximum possible load (in watts) to run appliances and lights. Remember, the wattage required to start a motor (on a refrigerator, freezer, or air conditioner) can be many times (up to 10) the normal running wattage. Starting wattage will be noted on the label with running wattage. Factor in this extra load.

COOLING

Most marine generators are water-cooled and can use one of three types of systems. Raw Water: Least expensive. This system circulates raw sea water through the engine. As a result, potential corrosion and contamination problems make them a poor choice for marine use. Heat Exchanger: Most common. Cool raw water is taken from outside the hull and continually passed over a series of coils that are part of the engine's closed freshwater cooling system. Only parts exposed to the raw water are vulnerable to excessive corrosion or contamination. Keel Cooled: This completely sealed freshwater system, foregoes the seawater cooling circuit, opting instead for the closed-loop, water-jacket circuit. A pump to move the coolant through a cooling grid located on the bottom of the boat. This keel cooler must be separate from the main engine's grid.

EASY ACCESS

Look for all common maintenance points, such as the dipstick, filters, and both oil and water fills, to be on one side of the generator body so they'll be close at hand.

SOUND ENCLOSURES

These reduce engine noise, but make access for maintenance difficult. Look for ones with removable panels so you don't have to remove the whole cover to do a small job.

CONTROLS

Typically, a separate unit mounted on top, or integrated within, the generator. Digital microprocessor controls offer significant diagnostic and monitoring capabilities compared to conventional relay controls.

ELECTRONIC FUEL INJECTION

Provides easier starting, lower emissions, and steadier running compared to carbureted engines. Get it.

AUTOMATIC SHUTOFF

Make sure the unit will shut off automatically if there's low oil pressure, high coolant temperature, loss of coolant flow, or high exhaust temperature in a wet exhaust system.

Updating Your Marine Generator Can Pay Off in Many Ways – Wareham, MA

Joseph Coupal - Monday, April 17, 2017
South Shore Generator - Kohler Marine Generator

New generators use less fuel, burn cleaner, and produce more power than their predecessors.

As the season nears, it’s a good time to assess any needs or shortcomings your boat might have. The engines were serviced and they’re purring like proverbial kittens. New props were installed and you managed not to ground them. The electronics are current, even the canvas looks brand new. But what about the generator?

Like an insurance policy, or even a loyal deckhand, many of us take the generator for granted. It always kicks on when we need it and provides much-needed juice for the myriad appliances many boats now carry.

Updating your boat’s generator can pay off in a number of ways. The latest and greatest models finally utilize electronic fuel injection to improve efficiency and reduce the output of carbon monoxide.

A control pad makes for simple operation.

Generator sizes are based on their output. The amount of kilowatts they produce is usually the number in the model name. Kohler is one of the manufacturers making low-CO generators, which reduce carbon monoxide emissions, making it safer and more comfortable to be aboard a boat while the generator is running. The Kohler uses throttle-body injection.

Kohler has its own small-footprint diesel model gensets starting with the 490-pound, three-cylinder 6EKOD, which produces 6 kW and offers sophisticated functioning and touchscreen interface. It fits in a 31- by 21- by 22-inch envelope, which should save space in your engine compartment. The 9EKOZD is also powered by a three-cylinder diesel and produces 9 kW. It fits into a 34- by 21- by 22-inch space and weighs 548 pounds. Finally, the 11EKOZD is an 11-kW model based on a four-cylinder diesel engine, weighing in at 616 pounds. Each Kohler genset is available in 50- or 60-hertz models and comes with advanced controllers that provide trouble-free operation. The new touch-style control pad has power and start/stop buttons, a two-line, 12-character display, and a simpler setup process. There’s even a USB port for quick software installations and maintenance downloads. The controller has power management, a fuel primer, a hybrid voltage regulator, and an interface with SmartCraft instrumentation.

If you’re wondering if you need a generator or you can still get by with an inverter, most experts say that if your electronic accessories require more than 3.5 kW, you need a generator. Add up the power requirements for each appliance you plan to run off the generator. Once you arrive at a total in kilowatt-hours, choose a generator rated to produce at least 20 percent more.

Trying to go cheap with a genset rated too close to your total will cost you in the end. Your new generator will wear out quickly and you’ll wind up buying the correct size replacement unit sooner than should be necessary. Don’t go off the deep end in the other direction either. Using an oversize genset runs the unit at an insufficient load, which will cause it to operate inefficiently, which increases fuel consumption. A generator should run at least at 25-percent load with the ideal being 35 to 70 percent.

Finally, if you like to take longer cruises, install a remote canister-style fuel-water separator in-line for your generator. Most gensets come with a small integral fuel-water separator, but the remote version can save you some headaches by preventing contaminants from getting to that smaller filter because it will clog quickly. Position the remote separator ahead of the motor in the hose routing and make it accessible so you can change the element or clean it out if it gets clogged.

What Size and Type of Back Up Generator Do You Need? Wareham, MA

Joseph Coupal - Thursday, April 06, 2017
South Shore Generator - Back Up Generator  Wareham, MA
  1. Portable. When the power goes out, you have to start up a gas-powered portable generator and plug it into your appliances or a subpanel. Portable generators cost $500 to $1,500 depending on power output.
  2. Standby. These generators are powered by natural gas or propane and start automatically during power outages. Prices start at $5,000 for a 7,000-watt unit, including installation.

How to determine what size generator you need Add up your power needs Estimate your power needs before you shop for a generator. Look for a label on each appliance that you want to power during an electrical outage. Add up the watts to determine the generator size you need. You can also get an idea of wattage requirements here. Wattage Requirements

  • Microwave: 600 to 1,200 watts
  • Refrigerator: 700 to 1,200 watts
  • Freezer: 500 to 1,200 watts
  • Washing machine: 1,200 watts
  • 1/3-hp sump pump: 800 watts
  • Television: 300 watts
  • Laptop computer: 250 watts
  • 10,000-Btu air conditioner: 1,500 watts

Your first step in adding backup power is deciding what you need (or want) to keep running when the electricity goes out. This determines the size (wattage) of the generator you’ll need. Walk through the house and make a list of everything you want to power during an outage. Look for a label on each appliance (they have to have one) that contains information such as wattage, model number and the year it was made (photo). Some labels are right inside the door on appliances; others are on the back, so you have to pull the appliance away from the wall. Write down the item and how much wattage it uses. Be sure to include essential items, like refrigerators, freezers, a well pump if you have one, and a sump pump if your basement could flood. You can go a few hours or even days without an oven (use the microwave instead) and an air conditioner—they use a lot of power and would require you to buy a much bigger generator. Add together the items’ wattages, then multiply that number by 1.5 (appliances need the extra power to start up). That’s the minimum wattage needed for your generator.

Size Up Your Generator Needs - Wareham, MA

Joseph Coupal - Tuesday, April 04, 2017
South Shore Generator - Kohler 8.5 RES-QS7

Even if it is a milder hurricane season this year, one tropical storm can inflict a lot of damage. So, how to size a generator and use it safely?

The experts at Consumer Reports say to pick a model with a wattage at least equal to the total of what you're powering. Manufacturers also suggest totaling the higher surge watts some appliances draw when they cycle on. A small portable, up to 4,000 watts, can typically power a refrigerator, sump pump, microwave, TV, and a few lights but you may want more oomph than that. Here are some recommended generators from our tests ranging from medium to large.

Midsized portable or small stationary, 5,000 to 8,500 watts

What it powers. Everything that a small model can power plus a portable heater (1,300 watts), computer (250 watts), heating system (500 watts), second pump (600 watts), and more lights (400 watts).

Recommended stationary. Kohler 8.5 RES-QS7, $3,200. Stationary generators turn themselves on and off when needed and run on propane or natural gas for longer runtime and safer fueling. The Kohler delivered smooth, steady power and offers 7,000 watts with natural gas and 8,500 using propane. It was also among the quietest of the stationary models we tested, and it shuts down automatically if the engine-oil level gets low. On the downside, it's pricey and requires professional installation.

Large stationary, 10,000 to 15,000 watts

What it powers. Everything you can run with a midsized model plus a choice of small water heater (3,000 watts), central air conditioner (5,000 watts), electric range (5,000 watts), clothes washer (1,200 watts), or electric dryer (5,000 watts).

Recommended model. Generac 6241, $3,500. This stationary generator was top-notch at providing ample, smooth power with consistent voltage. Generac claims the unit supplies 13,000 watts using natural gas and an additional 1,000 using propane. It also comes with a transfer switch, needed for safe operation. Among features are fuel shutoff, low-oil shutoff with an indicator, and electric start.

Choosing a Marine Generator – Wareham, MA

Joseph Coupal - Monday, March 20, 2017
South Shore Generator - Kohler Marine Generator

Today’s sport-fishing boats brim with power-hungry electrical equipment, from air conditioning to audio systems, spreader lights to live-bait pumps, refrigerators to radars and microwaves to water makers.

Supplying enough current for all of these accessories can pose a challenge, particularly on extended trips to fish remote waters with few marinas and no shore power. One option is to run the main engines to keep power flowing to the AC/DC system. Yet fumes, vibration, noise and fuel consumption render this practice annoying, especially on anchor or tied to the dock.

A quiet-running marine generator offers a more pleasing solution. Whether you’re adding, upgrading or ordering a new boat, consider these factors when choosing among the many brands and models of gensets.

Space Constraints

If adding a generator, think about location. Generators go below deck, often in the engine room or an aft compartment. Determine how easily you can access the space for installation and maintenance, as well as how the new unit will affect weight distribution.

For tight spaces, look at compact generator sets. On boats less than 30 feet in length, fitting in a genset could prove impossible. In these cases, a portable generator might be your only option.

Fuel of Choice

For convenience, choose a genset that operates on the same fuel as your boat. For example, with gasoline inboards, select a gasoline generator so you can tap the main tank.

There is one possible exception. On an outboard fishing boat, which runs on gas, it’s sometimes wise to have a diesel generator. Outboard boats rarely feature ventilation for below-deck compartments. Diesel (less volatile than gas) is safer to use in such enclosed spaces. You’ll need a separate diesel tank, so account for that when evaluating available space. If adding a marine generator you’ll also need to customize a system to usher air to the generator.

Most large sport-fishing boats usually have diesel inboards, so a diesel generator makes the most sense. Whether you choose gas or diesel, a separate canister-style fuel filter helps ensure delivery of clean, water-free fuel to the genset.

Output Options

Marine generators are rated by kilowatt output — from as little as 3.5 kW to as much as 200 kW. To determine the right model, add up the power needs for the accessories you plan to run. Then select a marine generator with about 20 percent more output than your total requirement. Resist thinking that more is better. A genset running at insufficient load leads to carbon buildup and other complications. On the other hand, don’t run all of your accessories at once. A genset operates best when carrying 35 percent to 70 percent of its rated load.

Installation Details

Gensets are water cooled, so when adding a unit plan on installing a water intake with a strainer to keep debris from clogging the cooling system. Also, you’ll need plumbing for cooling water to exit overboard.

As mentioned, gensets need air. Yet gensets also need exhaust systems. If adding a unit to your boat, plan on having a separate exhaust rather than sharing the engines’ exhaust system.

Most gensets come with remote ignition switches and basic gauges for installation above deck — usually near the helm or in a cabin — and a second control panel on or near the genset.

Quiet and Clean

Thanks to insulating shields, isolation mounts, mufflers and underwater exhaust, marine generators are quieter than ever. How quiet? Some generate just 66 decibels at a meter away. That’s about the same as a four-stroke outboard at 1,000 rpm when recorded at the helm. Carbon monoxide (CO) is a concern, especially with gas generators. Yet companies such as Kohler now make low-CO gasoline generators with lower emissions. The Kohler Low CO models feature self-monitoring systems that shut down the generator if CO builds to dangerous levels.

As the electrical demands of today’s sport-fishing boats grow, so too does the need for a convenient way to keep the current flowing. Today’s gensets deliver, whether at the dock or far from the marina.

The Right Size Generator for Your Home – Wareham, MA

Joseph Coupal - Monday, March 13, 2017
South Shore Generator for your home - Warenham, MA

Add up the items you need to power before making your choice

Power outages are often the collateral damage of severe snow and rain storms and other acts of nature. After you've experienced a few you're more likely to consider getting a generator to keep your home’s electricity humming. But before you buy think about whether you want to power your whole house or if you can get by for a few days with just the basics. Here's what we recommend when it comes to choosing the right generator size.

Generators come in two types: portable and stationary, also called standby. Portables cost less to buy and install, but you’ll need to keep it fueled and maintained yourself. A portable also needs to be wheeled outdoors, started, and connected to what you want to power. A stationary model, by contrast, needs to be professionally installed outdoors, which adds expense, but it starts automatically when power cuts off and also performs its own periodic checks—and displays a warning if it needs service.

What to Know About Wattage

To determine generator size, the easiest way is to add up the wattages of everything in your home you want to power with a generator. But some appliances, such as an air conditioner, refrigerator, and sump pumps, require more wattage (called surge watts) when they’re cycling on. It can also be difficult to gauge how much power certain hard-wired appliances, such as your furnace, require. For these reasons we suggest you consult with an electrician, and select a model with a slightly higher rated wattage that will accommodate additional products you might buy.

Also, figure in a few hundred dollars more to install a transfer switch, which allows easy connections for a portable generator. (Stationary generators often come with one.) This component also keeps utility power from frying the circuits you’re protecting once the power returns—and potentially protects any utility workers who might be working on the line. It also protects your generator.

Our generator buying guide lists what the various wattage ranges of both portable and stationary generators will support..

Get Wise About Size

To figure out what generator size you need, follow these simple guidelines. The larger the generator, the more you're likely to pay.

  • Just the basics: Small portable (3,000 to 4,000 watts)
    What it powers: Refrigerator, sump pump, several lights, television.
  • Basics plus creature comforts: Mid-sized portable or small stationary (5,000 to 8,500 watts)
    What it powers: The basics, plus portable heater, computer, heating system, well pump, more lights.
  • A larger load: Large portable (10,000 watts)
    What it powers: Everything above plus small electric water heater, central air conditioner, electric range.
  • The whole house: Large stationary (10,000 to 15,000 watts)
    What it powers: Same as large portables, plus clothes washer, electric dryer.

Some Top Performers

Here are some recommended models from testing over 37 models.

  • Kohler PRO7.5E, $1,400, a 6,300-watt portable that supplied plenty of power, and cleanly, with less noise than many competing models;
  • Generac RS7000E, $900, a 7,000-watt model that performed nearly as well;
  • Generac 6237, $2,250 (with transfer switch), a stationary generator that delivers 7,000 watts using natural gas and 8,000 using propane; and
  • Kohler 14RESAL, $3,700 (with transfer switch), a larger stationary generator that supplied 12,000 watts using natural gas—and 2,000 more with propane.

Whichever generator size you choose, don’t wait until a major storm is forecast to buy it. In addition to facing a more limited selection, you’ll cheat yourself out of the weeks you need to plan your purchase and get it installed before you can enjoy the protection of a generator that will serve you for years to come.

Stationary or Portable Generator? – Wareham, MA

Joseph Coupal - Monday, March 06, 2017
South Shore Generators - Generac 6237 portable generator

Your power needs, spending power, and ability to roll out the generator when it’s needed are chief criteria for choosing what’s best.

The choice boils down to cost vs. convenience. If you want to be ready for any power outage anytime, nothing beats a stationary generator. Once it’s installed, it just fires up—automatically—when needed. But most people choose a portable generator because it costs far less and is simpler to set up. Here are other benefits and drawbacks of each:

Portable Generators

Power output: For models that can connect to a transfer switch, usually 5,000 to 7,500 watts.

Price range (as tested): $500 to $4,000; inverter generators, $1,600 to $4,500.

Pros: A portable generator can be transported easily from one location to another. Setup is as simple as turning them on and powering items. And they can be shared among neighbors.

Cons: They run on fuel, and fuel storage can be a challenge. And though they include a number of power outlets, running extension cords to a portable generator also poses safety risks; that’s why a transfer switch is recommended.

Fuel needs: A 7,000-watt portable generator will use 12 to 20 gallons of gasoline per day if it runs continuously for 24 hours. More powerful generators use more fuel.

Stationary Generators

Power output: 8,000 to more than 20,000 watts.

Price range: $1,900 to $5,000 or more, plus installation (about $2,000 to $10,000).

Pros: They start automatically when the power goes out and often supply more power. They also periodically run a self-¬diagnosis routine that can alert you to problems. That enables you to get problems fixed before you need the generator. They run on natural gas or propane and save you the hassle and safety risks of storing fuel.

Cons: Beyond the higher cost of purchase and installation, they often require municipal permits and site approvals.

Fuel needs: A small 8,000-watt stationary model can run for eight to 15 days on a 250-gallon propane tank or indefinitely on a natural gas line.

A Greener, Quieter Alternative

Unlike most portable generators, which run at one engine speed, inverter generators have smart circuitry that varies engine speed depending on what they’re powering. That conserves gasoline and cuts down on the noise.

Another important benefit of inverter generators is that they dispense power smoothly at a consistent voltage. That so-called clean power (measured by the Total Harmonic Distortion, THD, in industry lingo) is less likely to damage the sensitive electronics found in computers, TVs, chargers, and many appliances today.

If that kind of clean, even power is a real priority, then consider a stationary generator. They provide more overall wattage and quality of power for the money, even when installation costs are factored in.
