I have a Mulitiplus-II, Cerbo GX running ESS, and some solar. I also run my own control program on a separate computer that communicates with the Cerbo's ESS and can programmatically change parameters based on state-of-charge and time-of-day.
I want my batteries to have a minimum state-of-charge before the grid's peak power rate starts. If I don't get enough solar power to recharge to the minimum before the peak rate starts, are there any issues with raising the Grid Setpoint value to force charging from the grid by setting it higher than the AC load? I just ran a simple test and confirmed I can force charging, but I want to check to see there's a better way or any potential negative consequences to doing so.
Thanks!
