Here's the setup:
4 100w renogy 12v panels in parallel
100ah Renogy LiFePo Smart
RVR40a MPPT
700w pure sine inverter (in parallel with the RVR40)
(all of these were purchased within the past month
Here's the issue:
When I measure the PV leads outside the RVR40, I read 22.4v, but as soon as I...
So I've tested all the connections between the panels and the MPPT and they all seem fine, and the voltage drops only across the terminals once the PV cables are installed. Could this still be the issue?
