EG4 24K Multizone Mini-Split AC/DC (Outdoor Unit) | R32

24K Hybrid Multizone Mini-Split Outdoor Unit

The brains behind your whole-home comfort. The EG4 24K Hybrid Multizone Outdoor Unit runs on solar, grid power, or both — automatically prioritizing solar whenever it’s available to keep your energy costs as low as possible. Support for up to three indoor zones means you can dial in comfort across multiple rooms from a single outdoor unit, all managed from your phone in real time.

Built for solar-integrated homes from the ground up, this isn’t a standard mini-split with a solar adapter bolted on — it’s designed to work natively with hybrid AC/DC systems, making it one of the most practical ways to run whole-home climate control off-grid.

Why it stands out:

• Runs on solar, grid, or seamlessly blends both — automatically prioritizing free solar energy first
• Controls up to three indoor zones from one outdoor unit for efficient whole-home coverage
• SEER2 rating of 22.5 with R32 refrigerant delivers strong efficiency in both heating and cooling modes
• Built-in AC power limiter lets you cap grid draw and maximize solar savings during peak sun hours
• Full app control for real-time monitoring, adjustments, and energy tracking from anywhere
• Quiet operation designed not to intrude on the spaces it’s conditioning

Design and Sizing: EG4-Multi-Zone-Mini-Split-Design-and-Sizing-Guide

Note: At least two indoor units must be installed for a single outdoor unit. Where total air handler capacity is greater than compressor capacity, the total heating or cooling capacity across all zones will be the available capacity of the compressor unit. You will need 1 lines set and 1 comm cable per indoor unit.
