220vac Off Grid Power Systems 48vdc LiFePO4 Lithium Battery

Product Specification

Complete 3000w 48vdc 220vac 380vac Off Grid Solar System LiFePO4 Lithium Battery
 
Description 
Off grid solar 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 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 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

• Type: Off Grid Solar System

• Areas without electricity such as mountainous and pastoral areas, border guard posts, communication base stations, island power supply, or areas with inconvenient and high electricity costs

• Household solar power supply: used in remote areas without electricity such as plateaus, islands, pastoral areas, border guard posts and other military and civilian life electricity, such as lighting, TV, recorder, etc.
