It is perfect sized inverter and I really like it’s features.I just installed the MPP Solar PIP 1012LV-MS.
It’s rated at 500 watts max PV input.
I have 4-250 watt panels with the following specs.
Rated Power: 250W
Open circuit voltage (VOC): 37.6 V
Max power voltage (VMP): 30.3 V
Short circuit current (ISC): 8.85 A
Max power current: 8.27 A
Power Tolerance 0/+3%
Maximum system voltage: 600V (UL)
Fuse Rating: 15 A
I contacted the manufacturer hoping to over panel so I could get 500 watts for longer in the day, and on cloudy days.
They responded:
Dear Dan,
Thanks for your information.
PIP 1012LV-MS can handle Maximum PV input power:500W, Voc:102Vdc, Isc:40A.
For panel which has the rated power: 250W, VOC: 37.6 V, ISC: 8.85 A
You can have Maximum 2pc of solar panels in series to get 500W, 75.2Vdc, 8.85 A
Or 2pc in parallel to get 500W, 37.6 V, 17.7 A
Thank you
Which brings me to 2 new questions:
Can I overpanel if I keep the voltage low ( ie. 2S2P? array)
Could I add a second MPPT controller and run 500 watts on each system?
Would that do any harm to my Hybrid system?
Any input would be greatly appreciated.
