Product details
Product information "PowerKeeper ST050CF + SH125CX-V11"
The manufacturer's specifications regarding installation location, assembly, installation and tools, fire protection, safety distances, etc., must be reviewed and confirmed on-site beforehand.
At least four storage modules are required per unit. All towers within a unit must have the same voltage level/height.
For parallel connection of up to four storage units, the PowerKeeper Combiner Box* is also required.
Please check whether additional data loggers or third-party EMS are required for the entire system (existing and new components) for the required interfaces.
Suitable lifting and transport equipment must be provided on-site. The accessibility of transport routes and passageways must be verified beforehand.
Need to quickly and easily add nearly 1000 kWh of modular storage capacity* to your corner? And no single element weighs more than 100 kg? The Sungrow PowerKeeper C&I Storage System makes it possible. Its modular, wireless stacking concept requires minimal installation effort while offering maximum versatility. The 12.48 kWh battery modules can be stacked up to five per tower and four in parallel* to create a total unit with nearly 250 kWh. Add the Combiner Box and cascade it four more times for an impressive 1000 kWh*. This is ideally combined with the Sungrow SH125CX C&I hybrid inverter featuring 10 MPP trackers and an integrated backup connection with a <10 ms switchover time. In addition to standard applications, the system offers new features such as smart trading, dynamic electricity pricing, and a virtual power plant.
