SKU: WLFP-51.2V-100Ah
Brand: HECKMAN

HECKMAN WLFP-51.2V-100Ah LiFePO4 Energy Bank (5.12 kWh)

Q: WLFP vs RLFP?

Same 5.12 kWh core—WLFP adds wall mount + LCD; RLFP targets rack density.

Q: Outdoor installation?

Install per IP rating and local code—typically sheltered locations with temperature limits per datasheet.

Q: Mix with ECOBSS STORE?

Avoid mixing HECKMAN and ECOBSS on one inverter without engineering approval—use one ecosystem per hybrid (BMS/CAN profiles differ).

Q: Inverter list?

Deye SG03LP1, SG04LP3, SG05LP3, and ECOBSS FLEX 3L only with validated CAN profiles—default Deye LV hybrids listed in compatibility.

The HECKMAN WLFP-51.2V-100Ah packages the same 5.12 kWh 51.2 V chemistry as RLFP into a wall-mounted enclosure with local LCD status—optimized for visible residential and small office installs.

Wall format simplifies homeowner acceptance: no rack aisle, minimal footprint, clean cable entry to a nearby hybrid inverter. CAN BMS integrates with Deye LP1/LP3 hybrids identically to RLFP—installer workflow differs only in mounting hardware and ventilation clearances.

Ten-year warranty positioning signals cycle-life confidence for daily tariff arbitrage. Displayed SOC aids troubleshooting without opening the App—useful when Wi-Fi monitoring is offline during outages—the exact scenario backup storage exists for.

Scale parallel WLFP/RLFP modules when single 5 kWh blocks insufficient; respect inverter charge current caps. Not for HV series strings.
