Chinese manufacturer Sigenergy has launched a new modular energy storage solution that combines a hybrid inverter and battery pack with a built-in energy management system. The inverter series offers a range of power options from 50 kW to 110 kW.
Sigenergy’s recently unveiled SigenStack energy storage system is specifically designed for the commercial and industrial segment and integrates a hybrid inverter and a battery pack with a storage capacity of 10.75 kWh. Sigenergy said the inverter series offers a range of power options including 50 kW, 60 kW, 80 kW, 100 kW and 110 kW.
The company said the system’s modular design allows the installation of four to seven batteries with a capacity of 10.75 kWh in one stack. By connecting multiple stacks, a single inverter can support up to 21 battery modules, giving a total capacity of 225 kWh.
“This flexible design facilitates multi-megawatt projects by allowing the connection of multiple inverters and energy storage systems,” Sigenergy said. “The system can be expanded via interconnected inverters and energy storage systems, making it an ideal solution for projects of all sizes.”
Sigenergy said the DC-coupled architecture includes pre-reserved energy storage interfaces, making it suitable for various scenarios such as pure solar, pure storage and hybrid setups with solar storage.
The SigenStack is housed in an IP66-rated unit and is suitable for outdoor installation, with Sigenergy saying the unit features a six-layer battery protection system, including temperature sensors, internal fire extinguishers and insulated pads.
“Once installed, the system requires no on-site maintenance and is fully manageable remotely,” the company said.
The SigenStor is available in single-phase models of 5 kW, 6 kW, 8 kW and 10 kW and three-phase models in power ratings of 5 kW, 10 kW, 15 kW and 25 kW. The battery is available in 5 kWh and 8 kWh capacities, providing up to 48 kWh of storage capacity per system, and the EV charger is available in 12 kW and 25 kW.
Sigenergy said the system is modular and can be stacked and connected in parallel to provide up to 960 kWh of storage capacity within one system.
The SigenStor is already available in Australia with the single-phase inverter and battery combinations approved by the Clean Energy Council (CEC), while the three-phase combinations are expected to be approved by the end of the month.
