Complete 3kw 48vdc 220vac Off Grid Solar Power System Solar Kit Home Use

Description

Off grid solar power systems are widely used in areas without electricity, power instability, islands, communication base stations and inconvenient wiring for street lights or monitoring systems. The utility-complementary Off Grid Solar Power System can realize the working mode of mixed utility and solar power supply, in which solar power takes priority and can automatically switch to utility power when the solar power supply is insufficient, with almost zero switching, without affecting the load.

Design of Off Grid Solar Power 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).
