DEYE SUN-5K hybrid 3-phase inverter 5 kW

The lowest-power variant of the DEYE SG05LP3 generation 5 series for low-voltage battery systems of 40–60 V. In the Czech Republic it holds legally valid PPDS A1+A2 certification (24/9/2025) and may be permanently connected to the distribution grid under the rules in force since 1/1/2025.

Asymmetric three-phase output of up to 2.5 kW per phase balances an uneven distribution of loads across the phases. During a short peak it handles 100% overload for 10 seconds — easily coping with the start-up of a compressor, pump or generator.

Two independent MPPT trackers (200–650 V) let you connect panels on roofs facing different directions without losing output. A maximum PV input of 8 kW corresponds to a panel array of ~6 kWp — an ideal size for a smaller family house.

A charge/discharge current of 120 A combined with a voltage range of 40–60 V suits a 15S or 16S battery system. Communication with the BMS over CAN or RS-485 — the inverter is fully compatible with BAKOM battery packs.

Smart Load function, monitoring via Solarman (Wi-Fi/Ethernet/LTE), IP65 protection and an operating range of −40 °C to +60 °C allow installation outdoors.

10-year warranty — full cover for the first 5 years, then parts only (excluding LCD/fan/labour) for the next 5 years.
