What is an 8 kW three-phase hybrid inverter with battery used for?
An 8 kW three-phase hybrid inverter runs a solar array and a battery from one unit, for homes. It decides how to use the energy: the house first, then the battery, and the surplus goes to the grid. At night or without sun it switches to the battery in under 10 ms.
- Four operating modes: maximum self-consumption, export priority, backup power and peak-price reduction.
- Panels facing different directions or with partially shaded areas: 4 independent MPPTs.
- Starting motors, water pumps and air conditioners: 12.8 kVA for 60 s in backup mode.
- Three-phase unbalanced load: up to 50% of rated power per phase.
Which batteries are compatible with the S6-EH3P8K-H-EU?
The S6-EH3P8K-H-EU is designed for Li-ion batteries of 120–600 V (up to 700 V according to the label). Maximum charge and discharge power is 8 kW, current is 50 A, and the battery connects over CAN or RS485. We pick the exact battery model from the manufacturer’s compatibility list.
How many solar panels can I connect to an 8 kW hybrid inverter?
The S6-EH3P8K-H-EU accepts up to 12.8 kW of usable PV power (160% of rated), and the recommended array size is up to 16 kW. It has 4 MPPTs and 4 strings with a 200–850 V range, up to 16 A per input, and a maximum input voltage of 1000 V. An existing grid-tied PV inverter can be connected for export control, and up to 6 inverters can run 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.”
On the same page ESO says that a storage system lets you reduce the power generated into the distribution grid, which in some cases makes it possible to connect a larger power plant than 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. The consultation before purchase is free.
