Key Features & Benefits
-
16.07kWh capacity (51.2V, 314Ah) — Store more solar energy to run loads overnight, during outages, or when utility power is unavailable.
-
15.42kWh usable energy — Delivers substantial real-world energy availability for daily cycling and backup needs.
-
IP65-rated enclosure (indoor/outdoor ready) — Helps protect the battery from dust and water exposure for more flexible placement options.
