Description
Modules stack on top of each other into a column, so no separate rack or cabinet is needed. Power grows with the module count at 2.5 kW each, so the column is sized for energy and, separately, for inverter power. Nominal module voltage is 51.2 V, which puts it in the 48 V battery class, and it connects to a low-voltage hybrid inverter. A breaker is built into the battery and isolates the column for service. Cycle life is at least 6,000 cycles. The IP65 enclosure keeps out dust and water jets. Certifications are IEC 62619, CE, VDE 2510-50 and UN 38.3, the last one being required for shipping lithium batteries.
How to choose
The column is sized by two conditions, overnight energy and inverter power, and each module adds 5.12 kWh and 2.5 kW. A home is covered by the Plus version up to 30.72 kWh, while the B ESS build up to 184 kWh suits a small commercial site. If the battery should hang on a wall together with an inverter, the RW-F5.1-1H2 at 5,000 W with 5.12 kWh blocks is closer, and for a rack indoors the NEPT S modules scale to 32 units.
