16 in 1 Compatible BMS that works with 16 brands of solar inverters

The cost and performance of lithium batteries continuously improve, the power density makes the consoles significantly smaller and compact. The round trip process, DC-to-storage-to-DC energy efficiency of the storage bank, or the fraction of energy put into the storage that can be retrieved, is one of the most important characteristics. That means less than 5% of your stored energy is lost in the conversion process. 


  • Extremely high efficiency, round trip efficiency 95%
  • Very low standby consumption less than 0.5Watt
  • Higher discharge and starting current compared to lead-acid
  • Energy density 100-200Wh/kg
  • Power density 1500-2000W/kg
  • Recharge time 1hour to 100%
  • Operating temperature from 0°C to 45°C 


  • We offer 48V50Ah (CATL)  batteries with sophisticated & reliable BMS.  
  • You can connect them in parallel to make 2.4kwh to 120kWh system. 
  • Easy to install and free of maintenance
  • Long-lasting (up to 6000cycles)
  • Can be used on-grid and off-grid
  • IEC62619 & UN38.3 certificates.
