The Sungrow PowerKeeper HV Battery Accessories (Expansion) Kit provides everything required to expand an existing PowerKeeper HV battery system quickly and efficiently.
Each kit includes the base, top cover, mounting hardware, cable duct, and all pre-fabricated power, grounding, and communication quick-connect cables, enabling fast plug-and-play connections between battery towers.
One PowerKeeper HV Battery Accessories (Main) Kit is required for the first ST050CF battery tower, while one Expansion Kit is needed for each additional series-connected tower.
For applications requiring full backup capability with the Sungrow SH100CX or SH110CX hybrid inverter, a minimum of five battery towers is recommended. Built for demanding outdoor environments, the kit features an IP66-rated enclosure with C5 corrosion protection and is engineered to withstand harsh conditions, including submersion in up to 50 cm of water for 24 hours when installed as part of an ST050CF battery tower.
*Please note that cables connecting the battery system to the inverter, as well as the main system grounding cable, are not included.
