Solis S6 10kW Three-Phase Low-Voltage 48V Hybrid Inverter
The Solis S6-EH3P10K02-NV-YD-L (part number SOL-S6-EH3P10K-NV-YD-L-UK) is a 10 kW three-phase low-voltage (48 V) hybrid inverter from the Solis SOLARATOR series. It combines PV generation with 48 V battery management (lithium or lead-acid, 40–60 V range), delivering three-phase backup power with UPS-level changeover of less than 10 ms and 200% overload for 10 seconds in off-grid mode. It features 2 MPPT trackers with up to 3 string inputs, a maximum usable PV input of 16 kW (160% oversizing), DC and AC coupling support, generator connectivity with auto control, and parallel operation of up to 6 units. Three-phase unbalanced output up to 50% of rated power per phase. IP66 rated with a 7-inch touchscreen, Bluetooth, and app-based commissioning. Available from DECO Group, a UK-based solar trade wholesaler.

Common Questions
Click a question below to reveal the answer.
What is the difference between the Solis S6 10kW and 15kW 3PH LV hybrids?
Both share the same SOLARATOR platform, dimensions (430 x 660 x 305 mm), weight (42 kg), efficiency (97.5% max), and feature set. The 10 kW accepts up to 16 kW PV input (vs 24 kW) with 3 string inputs (vs 4), has 220 A max battery current (vs 290 A), and allows 50% power per phase (vs 40%). Generator input matches the inverter rating.
How fast is the backup switching?
Backup changeover is specified as less than 10 ms, providing UPS-level switching for critical loads.
Can the Solis S6 10kW run off-grid without batteries?
Yes. The SOLARATOR series supports PV-only off-grid operation, though this is site design dependent.
Can I connect a generator?
Yes. The inverter supports generator connectivity with automatic on/off control. The generator maximum input power is 10 kW.
How many units can be installed in parallel?
Up to 6 units in parallel, providing up to 60 kW of backup power. Multiple units can operate together to form a microgrid.
