Deye hybrid inverters: what the brand brings, and when to actually pick it
Deye is what we install most often this year among Chinese hybrid inverter brands. The reason is simple: the SUN lineup covers the entire segment from 5 kW up to 50 kW, IP65 out of the box (we mount it outside without a cabinet), Wi-Fi monitoring through the SolarMan app works without extra purchases. RS485 and CAN interfaces give integration with most lithium batteries on the market. Our typical customer: private house 100-200 m², single-phase 220 V, looking for an inverter plus LiFePO4 battery as a kit.
What keeps Deye on top of our sales list. First: price. In the 6-10 kW segment Deye sits 10-15% cheaper than European peers like Fronius with similar 97-97.6% efficiency. Second: availability. The Deye factory ships in large batches, we keep stock at our Kyiv warehouse for top models. Third: 5-year warranty with 10-year extension option (ask for terms). One caveat: Deye periodically has stock-outs on top variants (SUN-6K-SG05LP1-EU, SUN-8K-SG04LP3-EU). If your timeline is tight, check availability before ordering.
Deye series: what we pick for what
The lineup splits by grid type and power. SG05LP1 (single-phase 220 V, 5-8 kW): our most-shipped segment for private houses with 48 V lithium battery. SG04LP3 (three-phase 380 V, 5-12 kW): for houses with three-phase service, also 48 V battery. SG05LP3-SM2 (three-phase, 14-20 kW): for estates and small businesses. SG01HP3-BM3/BM4 (three-phase with 500 V high-voltage battery, 30-50 kW): for production sites and farms. All models have built-in Wi-Fi and work with SolarMan out of the box, no separate dongle to buy.
What we ask before placing the Deye order. First: what battery is already installed or planned. If Pylontech, Hubble, Felicity, Deye plays nicely with them via CAN. If it is a custom pack with BMS, ask us, because protocols can be non-standard. Second: grid type. Single-phase or three-phase. Third: panel array, this drives the MPPT tracker count (2 or 3 across models). Warranty 5 years, delivery from our Kyiv warehouse in 1-3 days. Free calculation of the inverter-battery-panel kit.
| Model | Power | Phases / Voltage | MPPT Range | Application |
|---|---|---|---|---|
| SUN-6K-SG05LP1-EU | 6 kW | 1-ph / 220 V | 150-425 V | Residential home 80-120 m² |
| SUN-5K-SG05LP1-EU | 5 kW | 1-ph / 220 V | 150-425 V | Apartment or small house |
| SUN-8K-SG05LP1-EU | 8 kW | 1-ph / 220 V | 200-425 V | Home with AC and water heater |
| SUN-12K-SG04LP3-EU | 12 kW | 3-ph / 380 V | 200-850 V | Large home or small business |
| SUN-20K-SG05LP3-EU-SM2 | 20 kW | 3-ph / 380 V | 160-650 V | Commercial facility, farm |
The most popular model is the Deye SUN-6K-SG05LP1-EU (6 kW, single-phase): the optimal balance of power and price for a typical residential home. For three-phase grids, the most common choices are the SUN-12K or SUN-8K three-phase.
