EG4 24K BTU Multi-Zone AC/DC Solar Mini-Split Kit | Three 12K Indoor Units | 3.16kW Solar

EG4 24K BTU Multi-Zone AC/DC Solar Mini-Split Kit | Three 12K Indoor Units | 3.16kW Solar

Bring customized comfort to three spaces with the EG4 hybrid multizone mini-split kit. Featuring one 24,000 BTU outdoor unit and three 12,000 BTU indoor heads, this system delivers heating and cooling with individual temperature control for each zone. Its hybrid design supports direct power from compatible solar panels, a 208–240V AC connection, or a combination of both.

Enjoy a listed system efficiency of 22 SEER2, pre-charged refrigerant lines, included remotes, and convenient Solar Aircon app control. Each 12K head is recommended for rooms approximately 300–500 square feet, depending on insulation, climate, and room conditions. Backed by a 5-year limited warranty.

The three indoor heads share the outdoor unit’s nominal 24,000 BTU capacity. This configuration provides three zones of comfort; it does not provide 36,000 BTU of simultaneous system output.
