I'm trying to find the best solution for limiting my grid-tied energy system when my hybrid system batteries become full in an off-grid mode. I currently have an 18kW grid-tied system (2X Solaredge inverters) and a 4kW hybrid system (MPP Solar) with 48V batteries. The Solaredge inverters support power reduction through phase shifting. In an off-grid situation, I'd like to know if anyone has a solution for reducing, then turning off, the grid-tied system(s) when the batteries reach a certain threshold. I know it can be done with a DIY DC relay + high voltage AC relay, but it seems a little clunky. I also believe that there are hybrid system vendors that have phase shifting built-in (Victron, etc.), and would swap out the MPP Solar inverter if necessary, but I'm trying to salvage the current setup, if possible.
I believe the Victron Multi-plus II can perform phase-shifting. Are there any other vendors with products that do this?
Appreciate all your help.
Thanks!
