Since energy storage is a key part of energy transition and power transformation, Sunpack has developed a new 204V50Ah energy storage system, which is a safe, efficient and economical home energy storage system, An ESS can store surplus energy generated from rooftop photovoltaic panels for use when needed. When the sun has set, energy demand is high, or there is a black-out, you can use the energy stored in your ESS to meet your energy needs at no extra cost. In addition, an ESS helps you pursue the goal of energy self-consumption and ultimately energy-independent.

Slim design – Saving space. This lithium battery system is floor-mounted and firmly fixed to the wall.
High voltage system – Enhancing efficiency and responsiveness with lower current levels, minimizing energy losses during charge and discharge cycles.
Grade A Cells – Using high quality lithium iron phosphate battery as the main body of energy storage, with feature of large capacity, light weight and and higher safety.
Independent BCU (Battery Control Unit), in combination with the BMU of each battery module, offers complete protection including safeguards against over-voltage, over-temperature, overload, and overcharging.
Good compatibility – Standard communication protocol, CAN and RS485, compatible with most popular hybrid and off-grid inverters in the market.
Easy installation – Plug and play assembly, no more cables between modules, enhancing usage security.
