Whole-home power, one machine.
When the array is measured in kilowatts, the inverter has to speak high voltage. The PHSD3500 and PHSC5500 accept 4,000–5,000W of PV across a 120–450VDC MPPT window — string panels without combiner boxes — and pour it into a 24V or 48V bank while running the house on a 3.5 or 5.5kVA pure sine stage.
120–450VDC tracking range with 500VDC open-circuit headroom fits long panel strings, cutting balance-of-system cost.
Fast enough for computers and network gear. Overload handling is graded: 130% for 5s, 105–130% for 10s.
Solar only, grid priority, solar priority or hybrid — the hybrid mode blends both sources to shave peak tariffs.
8.8kg fan-cooled chassis with graded overload, short-circuit switch protection and 100A max charging from grid or PV.

Up to 5,000W of PV. With modern 550W panels that is a 9-panel string; the 120–450VDC MPPT window and 500VDC Voc limit support typical 6–10 panel series strings without a combiner.
The 3.5kVA model runs on 24V; the 5.5kVA on 48V. For continuous loads above 3kW, 48V keeps battery current manageable. Pair the 48V unit with our 51.2V 312Ah stackable ESS for a complete 15.9kWh system.
Yes — 5.5kVA covers a typical home: refrigerator, lighting, TV, router, washing machine and air conditioning with headroom. Non-essential high loads (electric showers, welders) should stay off backup.
