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.

Ideal for

  • ✓ Residential backup with visible battery aesthetics
  • ✓ Small offices pairing 5–15 kWh behind 6–12 kW hybrids
  • ✓ Retail showrooms demonstrating HECKMAN + Deye stacks

Technical FAQ

WLFP vs RLFP?
Same 5.12 kWh core—WLFP adds wall mount + LCD; RLFP targets rack density.
Outdoor installation?
Install per IP rating and local code—typically sheltered locations with temperature limits per datasheet.
Mix with ECOBSS STORE?
Avoid mixing HECKMAN and ECOBSS on one inverter without engineering approval—use one ecosystem per hybrid (BMS/CAN profiles differ).
Inverter list?
Deye SG03LP1, SG04LP3, SG05LP3, and ECOBSS FLEX 3L only with validated CAN profiles—default Deye LV hybrids listed in compatibility.
