Unnecessary grid import overnight
Hi A,
I got Sunsynk 3.6 wk inverter, 10kwh sunsynk battery, and 4.44 kwp PV array. Got my hot water cylinder switched on overnight for 1h. the heating element is 3kw. I noticed that during the hot water cycle, Im importing some electricity from the grid. Not sure why as my inverted is 3.6 kw and should be able to supply enough power. Yellow is the grid import. Has anyone got idea why is this happening?
