How the S6-EH3P6K-H-EU differs from the S6-EH3P5K-H-EU
| Parameter | S6-EH3P5K-H-EU | S6-EH3P6K-H-EU |
|---|---|---|
| Rated power (grid and backup) | 5 kW | 6 kW |
| Apparent power in backup mode (60 s) | 8 kVA | 9.6 kVA |
| Usable PV input / recommended array | 8 kW / 10 kW | 9.6 kW / 12 kW |
| Battery charge and discharge power | 5 kW | 6 kW |
| Rated output current (380 / 400 V) | 7.6 A / 7.2 A | 9.1 A / 8.7 A |
| European efficiency | 96.77% | 97.10% |
Both models have 3 MPPTs, a 200–850 V MPPT range, a 1000 V maximum input voltage, dimensions of 600 × 500 × 210 mm, a weight of 27.6 kg, IP66 and a 5-year manufacturer warranty.
Choose the S6-EH3P6K-H-EU when you plan an array of up to 12 kW, or 6 kW of battery power and a 9.6 kVA backup mode. If a 10 kW array and 8 kVA are enough, the S6-EH3P5K-H-EU is the lower-power option.
What is a 6 kW three-phase hybrid inverter with battery used for?
This inverter suits homes and small sites where the solar array can reach 12 kW, or where backup mode needs more starting power than the 5 kW model gives (8 kVA). Solar power feeds household appliances, then charges the battery, and the surplus is exported to the grid; at night the stored energy is used.
- Four operating modes: self-consumption, feed-in priority, off-grid and peak shaving.
- Battery charging and discharging by Time of Use (TOU) tariffs.
- Backup power: switchover in under 10 ms, 9.6 kVA for 60 s to cover the start-up current of motors, water pumps and air conditioners.
- Three-phase unbalanced load: up to 50% of rated power per phase.
Which batteries are compatible with the S6-EH3P6K-H-EU?
The S6-EH3P6K-H-EU is designed for Li-ion batteries of 120–600 V (up to 700 V according to the label on the unit and the packaging). Maximum charge and discharge power is 6 kW, current is 25 A, and the battery connects over CAN or RS485. We pick the exact battery model from the manufacturer’s compatibility list.
How many solar panels can I connect to a 6 kW hybrid inverter?
The S6-EH3P6K-H-EU accepts up to 9.6 kW of usable PV power (160% of rated), and the recommended array size is up to 12 kW. It has 3 MPPTs with a 200–850 V range, up to 16 A each, and a maximum input voltage of 1000 V. An existing grid-tied PV inverter can be connected for export control, and up to 6 inverters can run in parallel.
Why choose a hybrid inverter instead of a standard grid-tie inverter?
A hybrid inverter does more than export surplus to the grid: it can keep that surplus for yourself. ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
