Is a 12 kW 3 phase hybrid inverter with a low-voltage battery right for my home?
The Solis S6-EH3P12K02-NV-YD-L suits the largest 3-phase home solar systems with storage, when the battery voltage is 40–60 V and you need 12 kW of power.
- Solar with storage: up to 19.2 kW of PV input (160 % of nominal power); the recommended array is 24 kW.
- Backup when the grid fails: the switchover takes less than 10 ms.
- Heat pumps with SG-ready control and VPP / EMS platforms.
- Starting motors, water pumps or air conditioners off-grid: 200 % overload for 10 s.
- System expansion: AC coupling with existing PV, generator integration, up to 6 inverters in parallel.
What batteries work with the Solis S6-EH3P12K02-NV-YD-L?
This inverter works with 40–60 V lithium-ion or lead-acid batteries, with a maximum charge and discharge current of 250 A.
It has 2 battery ports and 1 BMS port, up to 150 A per port. The manufacturer publishes a separate battery compatibility sheet, and we use it to choose the exact battery model; the consultation before you buy is free. This model is not suitable for high-voltage batteries, so we will pick the right solution for you.
Backup power, motor starting and parallel connection
When the grid goes down, the Solis S6-EH3P12K02-NV-YD-L supplies 12 kW of backup power and switches over in under 10 ms (under 20 ms in a parallel system).
Off-grid, the inverter holds 200 % overload for 10 s, which makes it easier to start motors, water pumps or air conditioners. Up to 6 inverters of the same model can be joined into a microgrid, and the load can be unbalanced between phases: up to 50 % of nominal power on one phase.
How do I connect a hybrid inverter to solar panels, the grid and a generator?
The Solis S6-EH3P12K02-NV-YD-L connects to the panels through 4 string inputs and 2 MPPT trackers (up to 1000 V, 200–850 V, max. input current 40 A) and to the grid with a 3/N/PE connection.
The manufacturer lists several ways to connect a generator, with automatic control; the generator-side power is 12 kW. The electricity meter connects to the RS485-Meter port.
A hybrid inverter can do more than export surplus power to the grid; it can 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.”
On the same page ESO notes that a storage system lets you reduce the power fed into the distribution grid, so in some cases a larger power plant can be connected than the grid limits alone would allow.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
