Hello,
I have two Growatt 5000 inverters and 20 panels. My plan is to connect 10 panels to each inverter.
Please confirm or correct me if I am wrong ?
The inverters have Maximum PV Array Open Circuit Voltage: 450VDC and each panel has VOC 41.85V
When connecting panels in series voltages sum up and total max voltage going to each inverter should be 418.5V which I think should be ok. Is 10% margin good enough to stay on the safe side?
Panel specs:
Maximum power (Pmax) 380.00W
Maximum power voltage (Vmp) 34.50V
Maximum power current (Imp) 11.02A
Open circuit voltage (Voc) 41.85V
Short circuit current (Isc) 11.64A
Cell efficiency (%) 23.11
Module efficiency ) 20.37
Inverter specs:
Maximum PV Array Power: 6000W
MPPT Range @ Operating Voltage: 120VDC ~ 430VDC
Number of Independent MPP Trackers/
Strings Per MPP Tracker: 1/1
Maximum PV Array Open Circuit Voltage: 450VDC
Maximum Solar Charge Current : 100A
