Choose the S6-EH3P40K-H when you need 4 MPPT inputs, up to 80 kW of PV power or a 40 kW backup output. If the PV array stays within 60 kW and 30 kW is enough, the S6-EH3P30K-H may be all you need. The battery side is the same on both: two ports, up to 140 A in total, 150–800 V, and the dimensions (530 × 880 × 290 mm) and weight (73 kg) match.
What is a 40 kW three-phase hybrid inverter for business used for?
The Solis S6-EH3P40K-H suits a commercial site that needs a 40 kW backup output or a PV array of up to 80 kW across 4 MPPT inputs, whether it runs on-grid or off-grid.
- Backup power for critical loads: the switchover takes under 10 ms and the backup output is 40 kW.
- Sites with air conditioners and pumps: the 160 % overload for 2 s in off-grid mode lets heavy loads start.
- Systems on time-of-use tariffs: charging and discharging are scheduled by TOU tariff, and the inverter is ready for VPP integration.
How many solar panels can I connect to a 40 kW hybrid inverter?
Up to 80 kW of PV power (2 × rated power) can be used with the S6-EH3P40K-H, and the recommended maximum PV array size is 80 kW. The inverter has 4 MPPTs and up to 8 strings, with up to 40 A of input current per MPPT and up to 20 A per string, so it suits high-power modules, including 182 mm and 210 mm sizes. The MPPT voltage range is 150–850 V, the maximum PV input voltage is 1000 V and the start-up voltage is 180 V. PV can be connected through either DC or AC coupling.
Which high-voltage batteries can I connect to an energy storage inverter?
The S6-EH3P40K-H connects to high-voltage lithium-ion batteries in the 150–800 V range and supports battery modules of 100–280 Ah. It has two independent battery ports: up to 70 A each, 140 A in total, and charge and discharge power of up to 44 kW (up to 35 kW per port). Communication with the battery runs over CAN or RS485. The manufacturer publishes the list of compatible batteries, so Hybrid Energy checks every set against it before offering it.
Backup power, generator and parallel connection
When the grid fails, the S6-EH3P40K-H switches to backup power in under 10 ms and supplies a 40 kW three-phase backup output.
- Overload in off-grid mode is allowed up to 160 % of rated power for 2 s; a 100 % unbalanced three-phase output and half-wave loads are supported.
- The independent generator port (up to 40 kW, input power 20–100 % of rated power) has automatic start and stop control.
- Through the “three-in-one” interface a wind turbine and a diesel generator can be connected together with PV.
- Up to 6 inverters can be connected in parallel (up to 500 kW in total); for more than 6 inverters the manufacturer recommends a Solis STS cabinet.
Hybrid inverter with storage: connecting to the grid
The S6-EH3P40K-H connects to a three-phase 3/N/PE grid and complies with grid connection standards including G99, VDE-AR-N 4105 and EN 50549-1/EN 50549-10; a TÜV Rheinland conformity certificate has been issued under EN 50549. Monitoring is available through SolisCloud and the Bluetooth app.
A hybrid inverter can not only export surplus energy to the grid but also keep it 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.”
ESO also notes on the same page that a storage system reduces the power fed into the distribution grid, so in some cases a larger power plant can be connected than grid limits alone would allow.
