The DLXN 261 kWh outdoor battery cabinet is the storage half of a 125 kW commercial and industrial system. Thirteen sealed 64 V / 314 Ah LiFePO4 units — 20.1 kWh each — are stacked in one white outdoor enclosure with a black roof: 261.3 kWh nominal on the DC bus, ordered and sold as 261 kWh, of which 235 kWh is usable at 90% depth of discharge. The arithmetic is the same as everywhere else in the range: 64 V × 314 Ah = 20,096 Wh per unit, thirteen units make 261.3 kWh.
The extra unit over the 241 kWh frame is not cosmetic. It gives a 125 kW inverter about 2.1 hours at full discharge, which is the right shape for a site whose problem is a short, high peak rather than overnight autonomy: a demand charge set by a forty-minute interval, a compressor bank starting at shift change, or a DC fast charger added to a supply that will not approve a bigger import. Where a site needs both a hard peak cut and long autonomy, the honest answer is two frames, not one oversized battery.
Power comes from a 125 kW three-phase hybrid inverter, Solis or Growatt, selected at quotation against the grid code, the generator interface and lead time — DLXN configures, wires and commissions whichever is fitted. The inverter takes up to 250 kWp of PV on its MPPT inputs, about 350 modules of 710 W, while the battery sits on the DC bus and the grid and a diesel set connect on the AC side.
The enclosure is white painted steel with a black top, high-voltage warning labels on each access panel, and modules on a modular stacking frame for single-unit service access. Cooling is forced air through fans, so there is no coolant circuit to maintain. At 125 kW the AC breaker, cable and busbar are a size up from the 241 kWh build, and motor starting has to be checked against the inverter overload curve before loads go behind it.
Certified to IEC 62619, UN38.3, MSDS, CE and GB/T 36276-2023. Enclosure IP rating, cycle life, dimensions and weight are available on request with the cabinet document set — they are not estimated on this page. The cabinet is also sold as the battery half of the 125 kW / 261 kWh system, whose configuration and single-line diagram are documented separately.
