Panel Graham

Good shout from @CE_Builds and @JYT_Solar already. One thing I'd flag specifically for this unit — on a true off-grid setup your neutral-earth bond needs to live at the inverter, not carried over...

@Trigger the price is tempting but "Humsienk" sets off alarm bells for me. Never heard of them and that's usually a red flag with LiFePO4 rack units. Few things I'd want answered before...

@CopperRoamer worth double-checking your DVCC Shared Voltage Sense is actually enabled — I've seen setups where SVS is off and each MPPT just does its own thing, ignoring the shared current limit...
