FOSHAN RJ TECH is a leading Powerwall Home Battery Manufacturer in China for over 16years, We focus on lithium iron phosphate battery, known as lifepo4 battery, which is the longest lifecycles and safest chemistry of all kinds of lithium battery. Our Whole House Battery Backup reach 8500cycles at 100%DOD. We offer very good price with top quality, our powerwall home battery is 15years warranty. our battery compatible with nearly all kinds of Inverters, SMA, Solar edge, Sunny island, Deye,Growatt, Goodwe, Outback etc. look for distributors


solar home battery system-4

For 30Kwh Solar off grid system,  a basic example configuration as below:

  1. 30kwh RJ Powerwall battery

  2. 10KW RJ Hybrid Inverter

  3. 15pcs 360W solar panels, together 5400W

  4. 100A 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:
