[QUOTE="binky, post: 519114, member: 490"] what I was getting at, is if the battery is charged up or nearly full, there's nothing on in the house or very little, then perhaps it's trying to limit waht is being exported back to the grid to 16A or 3.6Kw. To be honest, the working of batteries is a bit of a mystery to me as I havn't got one myself, and can't sit around all day watching those I've fitted for customers. BUt if it's working and generally behaving itself it's probably best left alone. My one point of concern is that you say the battery depleted itself to 1%, I would be looking to set a minimum retained charge of around 10%. My reasons for this is the battery charging tends be very choked until around the 10%-15% level to protect the battery cells, so can be very slow charging until it can push more juice into the cells. One system I fitted took 2 days to get past this low start level, and mid winter we had to set it to take some charge from the grid because if the sun did come out, it failed to put much into the battery.
