[QUOTE="solar-forum, post: 530615, member: 35294"] No, you are not missing anything. But my original question was why that 2 kW had to come from the grid when we have a 5.2kW battery installed. But having now read loads of other threads here I now think that the grid draw is caused by the inverter checking the grid and also doing a "self-test" routine when the PV powers down in the evening and back on again in the morning. I can understand that monitoring and testing using some grid power, but 1-1.5 kwH pulled each day seems a lot. That tells me that there is an irreducible minimum grid usage and I will always face that. What I have also learned though is that it may be worth my while installing a solic (or similar) PV diverter to send surplus power to the immersion heater. We are currently exporting way more power than we use (and getting nothing for it because we are still waiting for the OK note from the DNO so I can't register for the odd 5.5p per unit we might get). My thanks to all who have replied to me here and in similar threads on the forum. I'm learning a lot. I do wish though that the solis "cloud" app would show more detail about the state of the battery. [/QUOTE]
