Hi everyone,
I have an AC50s which has 14-40v mppt controller in it and I've hooked up a Dokio 110w panel to it.
The problem is the most I've ever seen going into the battery is 48w. The following readings were taken on a clear sunny day afternoon in Florida.
Cold VOC: 21.8
Cold Amp: 5.9
Hot VOC: 19.4
Hot Amp: 4.95
When under load connected to the AC50s with a 50% battery, I'm seeing panel voltage drops to as low as 12v. I measured the current as well under load and the most I saw was around 3.7. Total wattage hangs around 45w in direct sunlight.
Yes I know I went cheap on the panels, but they do seem to be working fine. Is it that they are only 24 cells? Maybe I should have went with a higher voltage panel. I wasn't expecting 100w, but 80-90 would have been nice.
Is there a way to test what the cause of the low output is?
Thank you
