Hybrid inverter vs a standard grid inverter
A hybrid inverter can not only feed surplus into 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.”
The maximum continuous AC passthrough from the grid to the load is 70 A. Connection to the building’s wiring and compliance with the grid operator’s requirements must be handled by qualified specialists.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
