I bought a new RV which has Renogy 320w solar panel (at least that's what I was told) along with a Renogy 40amp MPPT. After seeing that my batteries were not staying charged I decided to upgrade to a Victron 150/60 MPPT. Once installed and connected I logged into the bluetooth to check the performance and noticed that I was only getting 70w out of the panel. It was a sunny day and there was nothing obstructing the MPPT was reading 70w output.
Other than the panel NOT being 320w what would cause such a loss in wattage?
