Complete 48vdc Off Grid Solar Power System 220vac Independent Electricity

Product Description

Complete 3000watt 48vdc 220vac Off Grid Solar System Independent Electricity Commercial
 
Description 

An Off Grid Solar System is not connected to the electricity grid and therefore requires battery storage. Off Grid Solar System can also be used in conjunction with generators/utility power/constitute a multi-energy complementary power generation system to supply power to the load. 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.
 
Parameters

Solar panel features

• With high efficiency polycrystalline / monocrystalline silicon chip, power generation is more stable and low attenuation

• The use of anti ash and easy to clean coated glass has high power generation efficiency in the later stage

• The module has good performance under extreme (temperature, load, impact) conditions

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
