off grid solar system.jpg

Sorry system off grid is for home appliance use, the power from sunlight will storage in battery, can use day and night.  It also can connect to grid, when there have lack power in battery, it will lend power from grid and can charge the batteries automatically to keep household appliances working.

Our solar system have made many projects for home and power station, successfully used by customer with very high efficiency , 5 to 6 years cost-recovering, 25years warranty, can use for 30 to 50years with free electricity obtaining.

Systems Introduction

Off grid solar system is most use for home,We supply 3kw 4kw 5kw 6kw 8kw 10kw 15kw 20k 30kw 40kw solar system for home use,50kw 60kw 80kw 100kw for project use, It is used for self household appliances, solar panel generate electricity to store power in batteries, customer can use it in any time. It is suitable for remote village, rural area or without stable utility grid.  

 If the inverter connect to on grid:

It means if solar system have no power, inverter will connect to city grid automatically to keep supplying electricity,Also it has batteries backup, If solar power is not enough, grid can charge batteries and supply power to your loads


20KW off grid solar system 


20KW solar system can generate 130 to 160KWH in a sunny day

The system include: 

48pcs of 410W solar panel+ mounting bracket+ cables+combiner box+controller+16pcs 250AH batteries+20kw inverter
