Twenty kilowatts AC with multi-module 51.2 V parallel stacks pushes combiner boxes, shunt currents, and maintenance complexity. This SKU remains valid when capital must stay in LV ecosystem inventory (HECKMAN RLFP/MLFP, ECOBSS STORE) and roof DC is moderate. Expect heavier DC cabling than 12K models—engineer cross-parallel wiring (positive to first module, negative to last) for balanced strings.
Feature parity with SUN-12K LP3: 50% single-phase asymmetry allowance (10 kW on one leg), GEN-port AC Coupling, up to 10-unit CAN parallel with Master-only BMS CAN, <10 ms load transfer. Peak shaving against 0.35 ₾/kWh B2B tariffs uses the same CT/PLC metering playbook—CHINT DTSU 666 default, Eastron SDM when distance exceeds 30 m.
Above ~40 kWh storage or 30 kW continuous hybrid power, model HV SG01HP3 TCO—including copper tonnage and labor hours. SUN-20K LP3 is the decision point: maximum LV density before RHFP HV strings win on BOS.
Ideal for
- ✓ Commercial clients insisting on 51.2 V HECKMAN/ECOBSS inventory
- ✓ Three-phase sites needing up to ~20 kW backup without HV switchgear
- ✓ Engineers comparing LV parallel count vs single HV string
Technical FAQ
When should I jump to HV instead of this 20K LV?
When stored energy targets exceed ~40 kWh, DC cable runs are long, or parallel module count exceeds maintainability—HV lowers current and combiner count.
Parallel limits?
Up to 10 SG05LP3 units on CAN parallel; energy storage BMS CAN only on Master; assign sequential Modbus IDs to Slaves.
Compatible energy storage units?
51.2 V LiFePO₄ only—HECKMAN RLFP/WLFP/MLFP and ECOBSS STORE series. HV RHFP are incompatible.
Cable sizing?
Follow Deye manual for 20K DC inputs—typically larger than 12K (approaching 50 mm² class for high continuous charge/discharge).
