Why Northern Lights Generators Beat The Competition

CitiMarine, one of South Florida’s premier marine service and sales outlets, recently shared these thoughts about Northern Lights quality:

Northern Lights Generators set the bar when it comes to marine generators.

If look up Northern Lights Generators on boating forums, such as The Hull Truth), you’ll see why Northern Lights is ahead of the pack.

Technicians who work on marine diesels and gensets for a living will tell you, Northern Lights are the best by far… simple and very well built.

Northern Lights generators have the best heavily dipped/insulated generator windings, as well as simple electrical wiring/engine harness/controls.

They are lower RPM engines (turn fewer RPMs than Onans or Westerbeke) leading to a longer-life and less problems.

We have received multiple reports of people using NL gensets season after season without so much as a hiccup, as well running the generators for 8,000 hours+ are common.

All that is needed is the occasional changing of oil and filters, and you’ll have a strong, dependable power-source on the waters that will never fail you.

TCSM – The Controller Tough Enough for the Commercial Marine Environment

As onboard power systems become more sophisticated, so the way that we interact with them must evolve. The commercial operator has a special challenge – finding controllers that are tough enough to withstand the marine environment, yet able to provide important data when you need it the most.

To address these needs, Northern Lights provides the TSCM “Tough Series” marine controller. With a backlit LCD screen and large, easy to read push buttons, TSCM is uniquely suited to the commercial operator’s engine room.

Currently available on Northern Lights commercial units up to 65kW, TSCM puts engine and electrical data at your fingertips. RS485 and J1939 protocols connect to a remote monitoring system. Because simplicity is always welcome in a commercial vessel, monitoring is available through a single data and power cable, up to 30 meters in length.

Northern Lights factory programs TSCM with pressure and temperature warnings and shutdowns to protect your power source. Other standard displays include battery voltage, run hours, operating status and an event log. Additional alarms and warnings can be added to meet your project’s specific needs.

Voltage and current monitoring is available on units 40kW and smaller. ECU codes are read on units from 50-65kW. All units can plug in with no additional adaptors required.

When you think Northern Lights you think simple durability. Our Tough Series of controllers make the industry’s best built products an even better value.

Installation Tips To Keep Your Generator Running Smoothly

You have done your due diligence, analyzed your loads, talked to your friends and neighbors. You have selected the generator set for your commercial vessel. But the selection process isn’t done yet. Installation must be considered. Among the most frequent service issues encountered relate to cooling and fuel systems. In the commercial waterways market, keel cooling systems are used almost exclusively. Heat exchangers and seawater pumps are to be avoided because of the likelihood that in-water abrasives (sand and silt) and fouling materials will plug water strainers and damage the pumps.


It is important the plumbing to the keel cooler is arranged to self-vent, can be easily filled and drained, and that the system includes a properly sized expansion tank. If the cooler is based on surface channels, it must be adequately sized for the worst possible operating conditions. For example: if the cooler is located on the side of the vessel and is held up against another hull or bulkhead, the generator engine must not overheat and shutdown. Proper coolant must be used, and service intervals must be followed, to avoid possible corrosion and freeze damage.


To ensure proper working condition, each generator set must have its own dedicated fuel supply and return lines to the tank, as well as progressive filtration. Use a coarse (30 micron) duplex pre-filter before the engine mounted final filters. Each generator set should also have its own dedicated cooling system, exhaust system and starting batteries (if it is an electric start application). Multiple redundant gensets are common to minimize downtime.


When designing the engine room, it is wise to ensure adequate space for standard generator service and maintenance requirements. When selecting a generator, therefore, it is helpful to choose one that has major service points on a single side. Make sure that ample space is available above and around the generator set to allow access for potential overhauls and equipment replacement.


If the generator is to be installed with a PTO, ensure that the base and brackets are strong enough to support the power take-off hardware without damaging it.
