Hello community,
i am unsure about the following panels im planing to set up:
I would like to run two of these panels parallel:
Does the MPPT 75/15 work if I connect these panels parallel?
I would then like to charge a 12V AGM battery, is that possible?(or only 24V batterys?)
Warm regards!
Connecting two of those panels in parallel exceeds the maximum short circuit current for that controller. If you connect them in series it would be safer but still over powered.
One panel could reach the limit for a 12v battery.
Is there a reason you want to use that controller?
For parallel connection the smallest controller I would consider would be a 100/20, the 100/30 would be a better choice.
I want to power a 75W fridge, and store the rest of the energy in a 115Ah AGM battery so the fridge keeps working für some more hours after the sun went down.
I asked for this specific controller cause it seemed to have the best price/performance ratio.
One panel is already too much for the 75/15 and you should at least use a 100/20.
For two panels you should use a 100/30 or for full performance the 100/50.
