Solar powered pond - part 5
learning lessons or lessons learnt? Ingenius idea.... may or may not be viable? I was watching the cycle of the battery being charged by solar panels (in November!) and then discharging by being used. This was during the day and it was rather novel as shown below (the variance around midday was due to me fiddling around with the cabling) As I was looking at this daily data, it got me to thinking.... that tailing off of power at the end of the day, that's not good, is it? I mean it's been great during the day, you see the batteries getting filled up, you see them being used / discharging, then up again and then down again...oh, then it got dark... and they carried on going down... and then they hit 12.3v and the ATS kicked in and switched the power over to 240v mains power. Ah, so the battery is currently at 12.3v, powering the inverter, so that will trickle down into the 12.1v range over a few hours... and then the battery starts to enter dangerously low territory. 12v...
