Product details
Product information "PowerKeeper ST050CF + SH125CX-V11"
The manufacturer’s specifications regarding the installation site, assembly, installation, required tools, fire protection, safety clearances, etc., must be reviewed and confirmed by the client/on-site team in advance.
A minimum of 4 storage modules is required per unit. All towers within a single unit must have the same voltage level and overall height.
A PowerKeeper Combiner Box is required for the parallel connection of up to 4 storage units.
Heated and non-heated battery modules must not be mixed within the same unit. When using multiple storage units with a BAT Combiner Box, both types may be used; however, the heating function will not be operational in this configuration.
For the entire system (existing + new), please verify whether additional data loggers or third-party Energy Management Systems (EMS) are required to support the necessary interfaces.
Appropriate lifting and transport equipment must be provided on-site. The accessibility of transport routes and passageways must be verified in advance.
Need to tuck nearly 1,000 kWh of modular storage capacity into a corner? And with no single component weighing more than 100 kg? The Sungrow PowerKeeper C&I storage system makes it possible. Its modular, cable-free stacking design ensures minimal installation effort while offering maximum versatility. Each 12.48 kWh battery module can be stacked five high per tower, with up to four towers connected in parallel to create a single unit with a capacity of nearly 250 kWh. By using a combiner box to cascade four of these units, you can reach an impressive 1,000 kWh. The system pairs perfectly with the Sungrow SH125CX C&I hybrid inverter, which features 10 MPP trackers and an integrated backup connection with a switching time of less than 10 ms. Beyond standard use cases, the system also supports advanced features such as smart trading, dynamic electricity pricing, and virtual power plant (VPP) integration.
