EnergySky SOLAR ASSIST

Off-grid photovoltaic system without grid feed-in

Solar support for air conditioning, heat pumps, and water heating. When the sun is shining, the system uses energy from solar panels. When solar power is insufficient, the system seamlessly draws the difference from the grid. It does not feed any electricity back into the distribution grid—therefore, you do not need a permit or approval from the utility company.

Solar Savings for the Devices That Use the Most Energy

Air conditioning, heat pumps, and water heaters are among the biggest energy consumers in the home. SOLAR ASSIST supplies them with energy directly from the sun during the day, reducing their operating costs.

Supporting Solar Energy Consumption

The energy from the panels goes directly to the device—not to the grid and back.

Automatic completion from the web

When solar power output drops, the difference is seamlessly made up by the grid. No outages.

No paperwork

No distribution licenses or approvals required. Installation without a lengthy approval process.

Easy to use

An enclosed solution with a Wi-Fi module. It connects to a single-phase air conditioner or heat pump.

EnergySky SOLAR ASSIST
