How large a home battery is needed?

Most households land between 5 and 15 kWh. Sizing follows evening consumption if the aim is self consumption, or the essential circuits and the expected outage length if the aim is backup.

Will solar alone keep the lights on during an outage?

No. A standard grid tied inverter disconnects when the grid fails, for safety. Backup during an outage requires a hybrid inverter with a battery and a defined backup circuit.

Portable power station or fixed installation?

A portable unit is right for a router, lighting, laptops, and a fridge for a few hours, with no installation. A fixed system is needed for whole home circuits, heating loads, and automatic changeover.

Sectors / Residential

When the house needs to keep running, we design the system behind it.

Homeowners want three things: uninterrupted power, lower bills, and equipment that lasts. We size and install residential systems the same way we do industrial ones — with real load studies, proper protections, and a maintenance plan.

Short answer

For homes the question is usually which of three things is needed: solar to cut the bill, a battery to keep essential circuits alive during an outage, or a portable unit for occasional use. EXBATT designs and installs rooftop PV, hybrid inverters, and home batteries, and supplies portable power stations for lighter needs, with local service in Kosova and Albania.

Whole-home backup.

Automatic transfer during grid outages, sized to real household loads rather than nameplate estimates. Clean, silent, and safe to run indoors.

Solar PV and self-consumption.

Rooftop PV designed around your actual usage profile, with inverters and monitoring that make production visible and controllable day to day.

Battery storage that lasts.

Lithium storage matched to the PV array and household demand, with correct protections, ventilation, and a service plan so the system still performs in year ten.
