I have a system with Multi Compact 2000, 2400 WH LFP batteries, 4 100 watt solar panels and a 100/30 MPPT controller in my travel trailer. I would like a mode that gives priority to solar power over grid power. Currently, if grid is available, solar power is only used for DC loads or battery charging.
The ESS modes are close if the requirement to feed power back into the grid could be changed to an optional setting.
I'm reluctant to set the grid code to Other just to make ESS work because if I understand things correctly, this could allow some energy to feed back into the grid which isn't generally allowed here in the US.
