Hi, We have 40 panels in an 20/20 east west orientation connected to a solar edge inverter. We have an air source heatpump and 3 phase Zappi so use a fair bit of electricity in the winter. Our existing installer will only supply Tesla powerwalls which are expensive when you have to buy one for each phase! Our inverter is a SolarEdge - SE10K-RW0TEBNN4 which I think might work with their battery (DC side) but I can't get an answer from SolarEdge as I'm not an installer. Possibly with an add on? Does anyone know about these inverters or do you know someone that I can ask for advice? Thanks, Barney
