How is this model different from other DC Generators we offer?
This model offers both 120/240V AC and 48V DC for battery charging. It accomplishes this by using an electronic charger specifically designed for DC batteries, along with an AC alternator. In contrast, our other generators typically use a DC alternator and do not provide an AC component. While having both options may cost a bit more, many of our customers find that it better suits their applications.
48 Volt DC Generator
When demand for battery power exceeds available charging capacity, help is often needed. This DC Generator uses a specialized DC alternator/generator with a high current rectifier and voltage regulator. It can produce up to 125 Amps, far more than most off-grid systems and chargers can.

Fuel Tank
The included internal tank holds enough fuel to run the generator over 24 hours. A fuel level gauge on the tank lets you easily see how much fuel is remaining. The generator controller also monitors the fuel level in the tank and can warn you when it reaches a set low point and even shut down the generator before it’s empty to make sure restarting is as easy as possible.
