Hello,
I have a system with the following components
Gridboss21 + Flexboss21 + 3 Outdoor rated 280Ah batteries in parallel + Generac 18kW generator.
I lost grid power and i wanted to try to see if the generator would power the batteries. I set the SOC to 83% to start charging and 90% to stop charging using the generator. Once the batteries fell to 83%, the generator started and a few minutes later it is supplying power to the house and charging the batteries - all looks good. But a few minutes later the generator is disconnected but is still running and i go back to powering off of the batteries. A few minutes later the generator is connected and starts charging the batteries and the house, but is again disconnected after a few minutes.
So there are a few things I could think of that might cause this.
1) the generator power is noisy, but i don't see any faults or errors in the logs indicating this.
2) the load is too high for my generator. I set the Adc to 40 and i still see this issue, so i don't think this is the problem.
3) my system settings are somehow incorrect
4) my firmware is outdated. My Flexboss is FAB-2525, Gridboss is IAAB-1600 so i don't see any issues
5) my BMS is causing issues?
The good news is the generator does respond to Charge Start SOC and Charge END SOC, but the Generator is still disconnecting.
Best,
Guy
