HV modules wire in series to reach the inverter's 200–850+ V window. Each module must be SOC-balanced before connection—unequal voltage causes immediate BMS fault. Master BMS CAN terminates at the HP3 inverter; Slaves never share battery CAN.
Modularity lets EPC teams scale kWh by adding series blocks in OPEN RACK HP or custom enclosures. BOS savings versus LV come from thinner DC conductors and fewer shunt points—critical on 30–80 kW hybrid feeders.
Compatible with Deye SUN-10…25K, 30…50K, and 80K HP3 models. Pair with heckman-open-rack for airflow and service access. OASIS cabinets compete at fixed 60 kWh increments.
Ideal for
- ✓ C&I ESS beyond 40 kWh where LV is cost-prohibitive
- ✓ EPC firms standardizing HECKMAN + Deye HP3 in Georgia
- ✓ Sites with long DC runs from battery room to inverter wall
