Product information "PowerKeeper STC 12.5-V1"
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.
