Wondering if anyone has thoughts or suggestions on this --- There must be some factor I am not accounting for.
I have two Victron BSC 12 volt 25 amp chargers on a Honda eu1000i generator to supplement the panels while I'm at the cabin in cold weather. The first day, the generator pushed the batteries up to 97%, then went into overcurrent protection mode. Yesterday, 90%, then overcurrent. Today, 80%. If I dial back one of the chargers to output 10 amps for a 35 amp total, the generator seems okay.
I believe the generator is rated for 900 watts continuous. I know that the chargers are 93% efficient (according to Victron). Even if a charger's output voltage has risen to 14.6 at 25 amps, that is 365 watts. If I divide that by .93, my best guess is that one charger, at its max, would be demanding around 392 watts from the generator. Two chargers, would be a little under 800 watts at the max. And that's at the end of the charge cycle just before the chargers go into absorption mode. Most of the time, total demand would be under that.
I do have the ECO mode enabled, but I don't see why that would be an issue. The chargers are a continuous load, it's not like they're cycling off/on and generating surges. In the absence of any other ideas, I'll turn it off tomorrow to see if that makes a difference. I wasn't too concerned about this on the first day (97%), but now it's taking a good bit longer to get the batteries back to full.
Thanks for your thoughts.
