I've got 5x 230 watt panels on the roof.
They're feeding into a EAsun 80A mppt controller.
I've got 8x 6v trojan batteries.
They're connected together in series, in groups of 2 to make 4x 12v.
I've got 2x 12v moto master batteries (they're new/1 year old)
I've got 3x pro point batteries (also new/1 year old).
So, that's 9 12v (flooded) batteries all connected in parallel (black to black to black and red to red to red).
Every morning, the V (volts?) Is usually in the very high 11.8-11.9.
On a good day in south Ontario, Canada...like today, it's super sunny.
It didn't take long for that 11.9 to get to 13v.
I've done 1 load of laundry, this morning, powered by the solar and my kitchen fridge has been plugged in, since I saw the V reach 12.5.
Everyday, whether I plug something into the solar or not...it starts in the high 11's.
It'll go up to 13 or a little higher, as the sun feeds the panels.
Then, as noon turns to evening and the sun slowly vanished behind the horizon, the 13.x slowly drops down to 12.5 and eventually rests at 11.8 or 11.9 as I start conserving solar energy.
Someone said I should let the batteries charge for a full week..and it'll consistently stay at the 13 as the batteries are full.
I tried that a couple weeks ago.
I didn't plug anything into the solar and this keeps happening.
Starts around 11.9
Gets to 12.5-13.5 by mid day and gently floats back down to 11.8-11.9 by bed time... And repeat.
I want to be able to plug my fridge in, full time and maybe have 2 or 3 days of reserve power for small things like charging devices or powering a TV during the day.
But... every night, the V goes down to 11.8-11.9.
What am I doing wrong?
Thank you for your help and patience with a guy just learning about this solar stuff.
