What should you look at before choosing?

Battery runtime starts with energy, not the 115V label. Estimate how much electricity the exact mini split may use in your building and weather, then include inverter losses, battery limits, temperature, other loads, charging, and the reserve you do not want to spend. Learn how to build a useful runtime estimate.

Choose the size

What does the space actually need?

Square footage is a useful clue, but it misses your windows, insulation, air leaks, climate, and ceiling height. A heating and cooling load calculation considers those details and helps you choose the right size.

Make sure the power works

Can your power source support this system?

The 115V label is only a starting point. Make sure your circuit and full power setup can handle the system, including the inverter, batteries, generator, solar charging, and other loads.
