How to choose a hybrid inverter for a family home in 2026?

The hybrid inverter is the heart of every modern photovoltaic system. We explain what to focus on when choosing one — power, phases, battery compatibility and savings.

What is a hybrid inverter and why do you need one?

A hybrid inverter converts the direct current from the solar panels into alternating current that can be used in the household. Unlike a conventional on-grid inverter, a hybrid inverter can manage energy from the panels, the battery storage and the grid at the same time.

For a family home, a hybrid inverter with batteries is now the standard — it lets you use your own energy in the evening, protects against grid outages and maximises the return on investment.

Single-phase or three-phase inverter?

It depends on your grid connection:

Single-phase connection (1ph) — typically older and smaller houses. You need a single-phase Deye hybrid inverter (6–12 kW).
Three-phase connection (3ph) — modern houses and businesses. You need a three-phase Deye hybrid inverter from the SG05LP3 series (8–20 kW).

How do you find out which connection you have? Look at your electricity meter — a three-phase connection has three phases L1, L2, L3.

What inverter power do you need?

The inverter power should match the size of your PV installation and your household consumption. As a rough guide:

Up to 6 kW — household without electric heating, consumption 2,000–3,000 kWh/year
6–10 kW — medium-sized family home, consumption 4,000–6,000 kWh/year
10–12 kW — large house with a heat pump, consumption 7,000–12,000 kWh/year
15–20 kW — large house, farm or smaller business — SUN-15K and SUN-20K

Golden rule: inverter power = 80–110% of the total power of the solar panels.

LV or HV battery?

Deye hybrid inverters support two types of battery system:

LV (low-voltage, 48 V) — simpler installation, suitable for houses and smaller businesses with an inverter up to 20 kW. For example Deye SE-F16-C (16 kWh), SE-F12-C (11.8 kWh) or SE-F5 Pro-C (5.12 kWh).
HV (high-voltage) — battery systems for HV inverters from 30 kW, suitable for businesses and larger sites.

For most family homes we recommend an LV system — simpler installation and servicing.

Recommended configuration for a medium-sized family home

Based on technical compatibility and the price/performance ratio, we recommend:

Inverter: Deye SUN-10K-SG05LP3-EU (10 kW, three-phase, LV)
Battery: Deye SE-F16-C LV (16 kWh, LiFePO4)
Both at a better price as the SUN-10K + SE-F16 set — current prices can be found in the sets catalogue

The battery covers approximately 4 hours of evening consumption at a typical load of 3–4 kW — that is, the whole evening into the night.

How much will you save?

At an electricity price of around 0.20 €/kWh (in many EU countries, including distribution charges), a 10 kWp PV system generates approximately 9,500 kWh per year. At 70% self-consumption:

Self-consumption from the solar panels: ~6,650 kWh/year
Annual saving: 6,650 × 0.20 = ~1,330 €/year
Service life of the panels: 25 years

The payback period depends on the cost of installation and on any subsidies in your country — an installation company will prepare an exact calculation for your house.

Conclusion

The choice of hybrid inverter depends on your grid connection, consumption and budget. For a medium-sized family home with a three-phase connection, the combination Deye SUN-10K-SG05LP3-EU + SE-F16-C LV is the optimal solution — also available as a ready-made set.
