What is a 12 kW 3 phase hybrid inverter used for?
The Solis S6-EH3P12K-H-EU suits a 3-phase home or business solar system with a high-voltage battery, where you need 12 kW of power and backup supply.
- Roofs facing different directions or partly shaded: the inverter has 4 MPPT trackers and 4 string inputs.
- Backup when the grid fails: the switchover takes less than 10 ms.
- Sites that want to control essential and non-essential loads separately: two backup ports.
- Longer backup with a generator connected.
- Cost optimisation by limiting peak power (peak-saving function).
Which batteries and generators work with the Solis S6-EH3P12K-H-EU?
This inverter works only with high-voltage lithium-ion batteries; the maximum charge and discharge power is 12 kW at 50 A.
The inverter talks to the battery over CAN. We choose and check the exact battery against the manufacturer’s compatibility sheet; the consultation before you buy is free. The inverter supports a generator: it detects AC voltage from both the grid and the generator and protects the generator from back-feed. Up to 6 inverters can be connected in parallel.
How does backup power work, and what are the two backup ports for?
When the grid goes down, the Solis S6-EH3P12K-H-EU switches to backup power in under 10 ms, supplies 12 kW and can deliver 1.6 times that power for 60 s.
The two backup ports let you separate essential and non-essential loads. The inverter handles an unbalanced load of up to 50 % of nominal power on one phase.
How do I connect a hybrid inverter to solar panels and the grid?
The Solis S6-EH3P12K-H-EU connects to the panels through 4 string inputs (up to 1000 V, MPPT range 200–850 V, short-circuit current up to 4 × 31.5 A) and to the grid with a 3/N/PE 400 V connection.
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.
What to know before you buy
- Battery: high-voltage lithium-ion only; this model is not suitable for low-voltage batteries.
