I had 10 solar panels and a battery installed a couple of months ago. I’ve an app which tells me how much energy is being collected, stored, sent to the grid, etc. But I notice I’m still being charged by my supplier for some electricity used. It’s not a lot - about a kw a day, but at this time of the year I’m not using much energy. Meanwhile up to 20 kw are being sent to the grid. Is this as it should be or is it possible that my battery settings are not right? If so what should I do?
