I am adding panels to an existing inverter+battery system and have planned the panel system as follows:
Existing inverter:
- MPP 4kW PIP-MS4048
- Max PV Input / Output: 3000 W
- Max Charging Current MPPT 60A
- Max PV Input Voc, MPPT Range: 145V, 60~115V
Planned panels:
- BlueTech POLY 345W
- Open Circuit Voltage: 46.2 V
- Voltage at Pmax: 38.2 V
- Max Series Fuse Rating: 15A
Planned panel configuration:
- 3 panels in serial, 2 sets in parallel, total 6 panels
- the combined voltage in serial is about 120 V which is near upper limits for the inverter's input, but is a hot climate and reasonably long cables so I think it will work OK?
Cabling:
- the 2 serial sets will join at basic cable splitter/combiner adapters
- panels to combiner adapters distance ~8m, use 3mm copper wire
- 15A fuse on each serial set's connection to positive adapter (2 fuses)
- combiner adapters to inverter ~20m, use 4mm copper wire
- DC Breaker near inverter 100A/1000V
Anything look wrong or missing?
