Not sure what to make of this. My current solar array is nine 100 watts panels in 3 series, 3 parallels. 15AMP X 60 Volts. 900 Watts.
At the moment, my trusty EB240 is giving me 495 watts. Which makes sense because max PV for the EB240 is 500 watts.
Then i switch the connection to my new EP500, and the PV goes down to 350 watts.
Going back and forth between the two shows a difference of 100 to 150 watts. The EP500 is getting less power than the EB240, which is kinda surprising. Going back and forth between the two takes me a few seconds to switch so it’s not changing weather patterns.
Not sure what to make of this.
The EP500 PV Input data is voltage 55-145vdc, max power input 12000watts, Rated Input Current 20amp.
Any thoughts on what i am doing wrong? My solar array is set at 15AMP, but that shouldn’t matter if the EP500 rated Input current is 20amp. I don’t think.
or is the new ep500 defective somehow.
any thoughts and/or advice would be much appreciated.
