I am trying to understand the minimum number of panels I need to get a 48-volt system up and running. While I'm sure a "minimum" is far from ideal, I can add on to the PV array and also add batteries as I can.
The inverter I am looking at shows the below specs for the PV array Using a reference panel of 330 watts. The panels I would like to use are 240 watts simply because I already have 3 of them but can get more. Here are the specs of the inverter:
My panel specs are:
By my calculations, I should be able to use 5 of these panels in one input to start with. That would give me:
1200 watts
PV array voltage = 152
PV array VOC = 186
Am I thinking about this in the right way or am I missing something? The plan is to start with a single 48-volt battery and build from there.

My panel specs are:
- Rated Power: 240W
- Open circuit voltage (VOC): 37.2 V
- Max power voltage (VMP): 30.4 V
- Short circuit current (ISC): 8.37 A
- Max power current: 7.89 A
- Power Tolerance 0/+3%
