R-Series
The R-Series is built for demanding energy solar battery storage applications that require durability, higher capacity, and long-term reliability. Designed for larger systems, off-grid use, and environments where performance matters most, the R-Series delivers massive capacity at a lower cost per kilowatt-hour without sacrificing durability or reliability.
With expansion up to 32 batteries x Parallel (457kWh), the R-Series is great for environments where power demand is high, uptime matters, and simplicity is important.
