I recently installed the 24v mpp solar all in one inverter. I have 2 12v batteries and 2 24v 270 watt solar panels connected to it. I an getting a reading of 34v off of the panels (it's a cloudy day) but the inverter acts as if there are no panels connected. It is showing 0 pv power coming in. Any ideas?

Once you have hit float, the mpp pip unit will not draw power from the pv unless there is a load running.
