20kwh Battery systems, Energy storage system

RJ is a lithium battery Manufacturer for over 16years, recognized by customers from Australia,Europe and North America. We offer Top quality with very good price for lithium lifepo4 batteries! RJ also has excellent partners who work with us for solar inverter, solar panels, solar charger mppt, with which RJ is capable of provding professional turnkey solutions to various applications for solar off grid and on grid system!

For 20Kwh Solar off grid system,  a basic example configuration as below：

1. 20kwh RJ Powerwall battery

2. 6KW RJ Hybrid Inverter

3. 10pcs 360W solar panels, together 3600W

4. 70A solar charger Mppt
   

Note this system is expansible, plug and play, you can simply add more lithium batteries to make a larger capacity system in the future. 

Besides the basic configuration we recommend, you can also do with your own preference. we have different optionsl for you, pLS check out different options in our website:
