EG4 36K Multizone Mini-Split AC/DC (Outdoor Unit) | R32

36K Hybrid Multizone Mini-Split Outdoor Unit

More zones, more flexibility, same solar-first intelligence. The EG4 36K Hybrid Multizone Outdoor Unit supports up to four indoor zones from a single outdoor unit — running on solar, grid power, or both, with automatic solar prioritization to keep energy costs where they belong. Whether you’re conditioning a sprawling single-story home or a multi-room setup with a workshop and garage, this unit handles it all quietly and efficiently from one central system.

Like its smaller sibling, this isn’t a standard mini-split with solar capability tacked on — it’s built natively for hybrid AC/DC integration, making it the most capable option in the EG4 multizone lineup for larger off-grid and solar-integrated homes.

Why it stands out:

• Runs on solar, grid, or seamlessly blends both — automatically prioritizing free solar energy first
• Controls up to four 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.
