Product overview
KH-ES2.5-WM2 powerwall is 2.5kwh 48v/51.2v 50ah lifepo4 lithium battery，is best home solar energy storage system, It has the advantage of mini portability and is convenient for DIY enthusiasts. It is the smallest solar house powerwall and cheapest li ion powerwall solution. It is the best tesla powerwall alternatives in the field of home energy storage.
The keheng storage systems capture excess solar energy to provide power when it is needed most—when the power goes out, when electricity prices spike, or when the sun isn’t shining. Keheng curates a portfolio of hardware options from internationally recognized battery and power electronics suppliers in order to provide homeowners and businesses with safe, reliable, and renewable power.
“5 kwh keheng battery eliminated the most difficult challenges we face when building microgrids in remote tropical locations. The batteries are much easier to transport and they have a good chance of lasting the entire 20 years. This means kh-es5kpw batteries generally pay for themselves in under 4 years!”
