The editor has been asked most recently about the solar power system package. The following is a comprehensive summary of the various problems of the solar system package.
The solar power system package includes a solar panel, inverter, combiner box, and LifePO4 battery.
Some people ask, what parameters should I choose based on? The editor's answer is the most simple and direct way, which is to choose the inverter first, and then choose the matching solar panel and battery, and the combiner box can match the solar panel.
The following is an example introduction to the optional inverter and solar panel. When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage of PV modules not exceeds the max. PV array open circuit voltage of the inverter.
2. Open circuit Voltage of PV modules should be higher than min. battery voltage.
For example,
INVERTER MODEL | 3.5KW | 5.5KW |
Max. PV Array Open Circuit Voltage | 500Vdc | |
PV Array MPPT Voltage Range | 120Vdc-450Vdc |
Take 250Wp PV mold as an example. After considering the above two parameters, the recommended module configurations are listed as the below table.
Solar Panel Spec. 250Wp Vmp: 30.1Vdc Imp: 8.3A Voc: 37.7Vdc Isc: 8.4A Cells: 60 | SOLAR INPUT | Qty of panels | Total input power |
(Min in serial: 6pcs, max. in serial: 13pcs) | |||
6 pcs in serial | 6 pcs | 1500W | |
8 pcs in serial | 8 pcs | 2000W | |
12 pcs in serial | 12 pcs | 3000W | |
13 pcs in serial | 13 pcs | 3250W | |
8 pieces in serial and 2 sets in parallel | 16 pcs | 4000W | |
10 pieces in serial and 2 sets in parallel | 20 pcs | 5000W |
