Hi There, based in the UK. I'm thinking to use the Multiplus-II or Easy solar-II unit to charge a 15khw battery during the off-peak hours and reuse the battery to supply the house during the day, using the ESS, Parralelle grid function. Assuming I fit a 5kva variant. If the house load is over and above the output of the MP unit, will it share the load with the Grid. ie. Let's assume the house load is 10kw, can the MP supply 4kw and the grid 6kw or would the MP shut down and allow the grid to supply all 10kw of load.
