I have noticed on certain days when there is clear blue sky and the temp is around ~33 or so that our solar panels do not input charge even though we may be down to perhaps 70% SOC.
Has anyone else had this problem?
The system is 2 x 150w panels and Enerdrive electrics.

Hi Richard
Others have given some suggestions to look at. I would say have a look at the panels to see how many cells they have, just by counting them. Normally 36 is the standard for battery charging but some have less 32 or 30 cells. This reduces the voltage available and under very hot conditions there may not be enough to charge ? A definitive answer is to measure the voltage at the input terminals of the controller with a multi meter.
Does the enerdrive controller/regulator have a display that will tell you what it is doing, eg the panel voltage, panel current, battery voltage, battery current etc.
I would measure voltage at each solar panel see what reading is using a volt meter, important to measure each panel individually means isolating each panel wiring wise in case one panel is faulty dragging good one down , unusual to have both panels faulty. Might give you a further clue. goodluck.
Thanks all for your replies, problem is now sorted, the system needed to be synced reasonably regularly for the BM system to operate correctly, system has been synced and all is now well. Due to no traveling because of CV I had not synced it for over a year.
