“CMX LFP48280 powerpro lifepo4 battery for solar storage 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 CMX batteries generally pay for themselves in under 4 years!”

The tesla powerwall alternative from CMX is one of the best source I got from China. This powerwall with 14 kwh energy. When I use 2pcs for the small system works perfectly with my growatt 10kW inverter. Our customer love this Coremax powerwall so much and most important it can really last.

This is a perfect lithium 48v 280ah battery powerwall I have ever got from China. CMX use laser welding for these prismatic lfp cells and the BMS can communicate with my sol art 8000w and 12000w inverter. it shows all information. thanks guys. a cheaper alternative to tesla powerwall.
