Complete 5kw Off Grid Solar Power System 380vac Home Use

Product Specification

Complete 5kw 48vdc 220vac 380vac Off Grid Solar System Home Use
 
Description 

Off Grid Solar System is widely used in areas without electricity, power instability, islands, communication base stations and inconvenient wiring for street lights or monitoring systems. The photovoltaic array converts solar energy into electricity when there is light, and stores the electricity in the battery bank through the solar controller; when there is no light, the battery bank discharges through the solar controller to supply power to the DC load, and can also reverse the discharge into AC power through the inverter to supply power to the AC load.

Design of Off Grid Solar System

• According to the load size and type, single-phase 220V or three-phase 380V, the rated power of off grid inverter is determined.
• According to the discharge time of the energy storage battery required by the load, determine the size of the energy storage battery (such as how many kwh to store).
• According to the load power consumption (how many kilowatt hours of electricity) and the local sunshine situation, select the board with high power.
• The size of charge controller is selected according to the size of photovoltaic panel and battery voltage.
• Supports, cables, etc. (installed on the roof or floor).

Application
