Question:
I’m setting up a small off-grid cabin that has occasional generator power. Can a PowerMax converter handle charging batteries and running 12V loads at the same time?
asked by: Eric
Expert Reply:
Yes, Eric, standalone PowerMax 12v ac to dc converters like the # PM94VR 55 amp or # PM44VR 60 amp are designed to do both jobs at once. When your generator is running, the converter will supply 12V power directly to your lights, water pump, or fans while also charging the battery bank in the background.
This would work really well in your off-grid cabin since you have a generator to help keep batteries charged via the PowerMax converter. You can even use fixed-voltage mode to hold a steady charging voltage during generator runs to get the most out of that time / generator fuel.
What size battery bank are you planning to use in the cabin?
