I'm now in the process of making another major update to my systems which will have to include a revisit on the generator aspect. It will need to be capable of providing 240V/60A+ for charging & passthrough power. That will certainly bring a few new challenges hehehe...
With the smaller gennies, even like the
4650W Champion Inverter I am presently using, it's really best not to pull too much. I use my Inverter/Charger set to 80A Charge for my 24V Bank, this is pulling 120V/23A +/-1,2A (2700-2850W) from the L5:30 Plug which leaves enough to handle the Fridge or Well pump start surges. I have tried to use more power but I felt the genny was struggling too much and not worth it. I do have an Advantage with the Samlex Inverter, it does compensate for the surges from the battery bank when needed and that does reduce generator load stress quite a bit, not all Inverter/Chargers or AIO's can do this, especially the budget ones. You really have to UPSIZE the Inverter Generators to make sure that you are pulling from the "Running Watts" range when charging your battery systems while leaving a bit of room for other things that are running on the system.
