I installed 4 solar panels on my roof each of 250 W. And a hybrid inverter (which the seller said can support up to 3000 W). I have got two 175 Ah batteries with it.
Things seemed to be working fine, until I recently found out that I could connect that inverter to the laptop via USB and check different readings.
When I did that, I was amazed to see that it was showing the current coming form the PV (solar panel) is about 550 W. This was when the sun was right in front of the panels. I called the guys who fitted it to see if one panel was dead or something, they checked, and turns out they are all giving 8 A each, so I thought there could be losses in the wire that is connecting the panels to the inverter, however, we checked the voltage right before the wire coming from the panels is plugged into the interver, and it was showing 32 A @ 32 V which is about 1000 W.
The issue is, the inverter still insists that the current coming from the PV is around 500 W.
If I put a load of about 700 W (by turning on all the fans and lights) it starts drawing current from the batteries.
Is this normal? Should I get the inverter checked? Here is the screenshot of the app that came with the inverter showing all the information.
