System: MppSolar LV6048 with a 48V LifePo4 battery bank.
My problem is that I don't have a large enough generator to provide the Utility Input when I am running heavier loads. One of my problems I have discovered with my MppSolar inverter is that when it switches over to the Utility mode it must provide both the load and the battery charging from the generator. If I have a load (AC unit) running the load will over load the generator and fault. I was hoping that I could configure it to just use the ultility/generator input to just provide additional charging to the battery bank, but still remain in battery mode to provide the load. That is not possible from what I can tell.
There are times when I may run the AC into the night after there is no PV charging the battery. Eventually after a few hours the temp will come down and the AC will automatically shut off. If I am at a bit of a deficiency on my battery storage a few hours of a 1600Watt generator will extend my power demand and get me where I need to be.
Can I just go around the inverter charger and hook up a 48V lifePo4 battery charger directly to the the busbar on my battery bank and supply the battery charger with my Predator 2000 inverter generator to charger? The battery charger may not actually charge much or at all if the demand is over the amps being supplied, but would it just be consumed by the inverter in those cases and supplement the amps coming out of the battery bank?
obviously my first choice for the battery charger will be an EG4 25 amp via the affiliate link on Will's website. The generator should power that charger with about 14 amps to provide something within the 5a-25amp range on the charger.
