10 kW hybrid inverter: when we install it and when 8 kW is enough
We typically install a 10 kW hybrid inverter in large homes 180-250 m². Our customers this year run a two-storey house with a heat pump rated 8-10 kW. Plus a couple of AC units. Plus a water heater. Sometimes a 7 kW EV charger. If you have no heat pump and no EV plans, an 8 kW unit is sometimes enough: cheaper, smaller footprint. The 10 kW peaks at 20 kW briefly. It holds simultaneous compressor starts without voltage sag.
How it works: when the grid is up, we draw from it in parallel. Surplus from PV panels goes into the battery or back to the grid (if you have Net Metering). Grid drops: the unit transfers to battery in 10-20 ms, then re-engages solar. No interruption. One caveat: a 10 kW inverter wants a 12-15 kW PV array to generate properly. 6-7 kW of panels will not load it correctly.
Single-phase or three-phase: what we install most often
Single-phase 220 V on a large house: rare but it happens. We pick Veichi SISV-10.2K-H(TWIN) with MPPT 60-450 V and 98% efficiency. Goes well in our shop for cottages with an older single-phase service. Alternative: Deye SUN-10K-SG04LP3-EU. Three-phase 380 V for 180+ m² houses: this is the main segment. Veichi VHT-10K-25-H with MPPT 200-950 V (from the manufacturer datasheet), high-voltage 750 V battery, IP65 for outdoor mounting. If you plan a 14-18 kW PV array on the roof, we ship VHT-10K-40-H: the 40 A charge current will keep up.
What we ask before placing the order. First: are you planning an EV or a heat pump in the next 2-3 years. If yes, better to leave headroom and look at the 12 kW unit. Second: what service the house has, three-phase 380 or single-phase 220. Third: what the panel array will look like, this drives the MPPT tracker count. Warranty 2-5 years, delivery from our Kyiv warehouse in 1-3 days.
| Model | Grid | Efficiency | MPPT Range | Max Charge Current | Application |
|---|---|---|---|---|---|
| Veichi SISV-10.2K-H(TWIN) | 1-ph 220V | 98.0% | 60–450 VDC | 140 A | Cottage, farm, office |
| Deye SUN-10K-SG04LP3-EU | 1-ph 220V | 97.0% | 200–850 VDC | 210 A | Large house, solar station |
| Veichi VHT-10K-25-H | 3-ph 380V | 98.1% | 200–950 VDC | 25 A | Manufacturing, 3-phase grid |
| Veichi VHT-10K-40-H | 3-ph 380V | 98.4% | 200–950 VDC | 40 A | Commercial facility |
For single-phase 220V grids, the most popular model is the Veichi SISV-10.2K-H(TWIN) (23 units sold in 12 months) thanks to its 98% efficiency and wide MPPT range starting from 60V. For three-phase installations, we recommend the Veichi VHT-10K-40-H with IP65 protection and 40 A charge current.
