We are a leading manufacturer producing quality protection products and charging stations for solar photovoltaic, battery energy storage, and EV charging systems. Our solutions are certified by SAA, CB, CE, TUV, UKCA, ISO, and RoHS, featuring patented designs and innovative fire protection technologies.

HIGH SAFETY AND SUPER HEAT DISSIPATION: Our energy storage battery packs use top-ranked A-class automotive LiFePO4 cells for greater safety and longer cycle life (up to 5000 cycles at 80% DOD). The all-aluminum body ensures a larger heat dissipation area.

Equipped with a digital display allowing users to monitor voltage of each cell, rated voltage, capacity, temperatures, and BMS parameters in real-time.
Enables ultra-fast charging to reach full capacity in just one hour. Built-in intelligent BMS protects the module.
Operates efficiently in both low and high temperature environments:
Charge: 0ºC~ 60ºC
Discharge: -20ºC~ 60ºC




Our solutions are instrumental in the success of numerous projects across Australia, Germany, France, USA, Brazil, and more. We attend global exhibitions every year to stay at the cutting edge of market demands.
