Solis S6-EH3P5K-H-EU 5 kW three-phase HV hybrid inverter

The Solis S6-EH3P5K-H-EU is a 5 kW three-phase HV hybrid inverter for sites with a PV array of up to 10 kW and 5 kW of battery power: 5 kVA on the grid, 8 kVA for 60 s in backup mode, up to 8 kW of usable PV input and 96.77% European efficiency. Backup switchover takes under 10 ms, it works with 120–600 V Li-ion batteries and up to 6 inverters can run in parallel. If you need more PV and backup power, look at the 6 kW S6-EH3P6K-H-EU.

How the S6-EH3P5K-H-EU differs from the S6-EH3P6K-H-EU

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-EH3P5K-H-EU when the PV array stays within 10 kW and 5 kW of battery power and 8 kVA for 60 s in backup mode are enough. If the array is larger or backup mode needs more starting power, choose the S6-EH3P6K-H-EU with 9.6 kVA and a recommended array of 12 kW.

What is a 5 kW three-phase hybrid inverter with battery used for?

This inverter is meant for homes and small sites with a solar array of up to 10 kW and a battery. Solar power feeds the household loads first, then charges the battery, and any surplus goes to the grid; at night or when generation is weak, the stored energy is used. In backup mode it gives 8 kVA for 60 s, and if that is not enough, the 6 kW model (9.6 kVA) fits better.

• Four operating modes: self-consumption, feed-in priority, off-grid and peak shaving.
• Battery charge and discharge schedule by Time of Use (TOU).
• Backup power: switchover in under 10 ms, 8 kVA for 60 s.
• Three-phase unbalanced load: up to 50% of rated power per phase.

Which batteries are compatible with the S6-EH3P5K-H-EU?

The S6-EH3P5K-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 5 kW, current is 25 A, and the battery connects over CAN or RS485. Each battery is wired to its own inverter over a separate CAN line. We pick the exact battery model from the manufacturer’s compatibility list.

How many solar panels can I connect to a 5 kW hybrid inverter?

The S6-EH3P5K-H-EU accepts up to 8 kW of usable PV power (160% of rated), and the recommended array size is up to 10 kW. It has 3 MPPTs with a 200–850 V range, up to 16 A each, and a maximum input voltage of 1000 V. If one building needs more power, up to 6 inverters can be connected 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.”
