About this mini-split
Same platform as the 9K, sized up to 12,000 BTU. Rule of thumb: 9K does one room up to about 500 sq ft, 12K does one room or open area up to about 650 sq ft. Same Plug-n-Cool pre-vacuumed lineset, same 115V single-phase wiring, same Wi-Fi app.
SEER2 still in the high twenties. Inverter-driven, R32 refrigerant, pre-charged. Heat-pump rated for shoulder-month heating in mild climates.
Energy Star certified, AHRI listed, 5-year limited warranty.
Pick this if you want EG4 efficiency without the DC solar input. For the same 12K BTU with solar-direct DC, see the 12K Hybrid.

EG4 12K BTU Hybrid Solar Mini-Split (AC/DC R32)
This is the model that actually plugs into your solar array. Two power inputs: 115V AC from the grid, and 90 to 380 VDC straight from a string of panels (up to 1,100W, 12A max). Built-in MPPT prioritizes the solar input during the day and hands off to grid power when the panels aren't producing. That means a small array, four to six 300W panels in series, can run the mini-split for free during sunlight hours without an inverter in the loop. Off-grid customers can pair it with a charge controller and a small battery for after-dark cooling. Grid-tied homes use it as a daytime offset that runs whether or not net metering is in play. 12,000 BTU of cooling and heat-pump heating. SEER2 around 22.5, HSPF2 around 9.7. R32 refrigerant pre-charged (about 27 oz). Cooling operating range 32 to 131°F outdoor, heating range 5 to 86°F outdoor. Max lineset 49 feet, pre-vacuumed quick-connect included. Indoor unit 21 lbs, outdoor unit 71 lbs. 5-year limited warranty. Energy Star and AHRI certified.

EG4 24K BTU Hybrid Solar Mini-Split (AC/DC R32)
Bigger brother of the 12K hybrid. Same solar-direct DC concept, sized for a 24,000 BTU load: open floor plan, two zones connected by a doorway, a barndominium, a small shop. Important difference: this one needs a 208 to 240 VAC circuit, not 115V. DC solar input is 150 to 380 VDC, up to 2,200W, 20A max. Plan for an 8 to 10 panel string sized to that window. SEER2 around 21, HSPF2 around 7.9. Slightly lower than the 12K because moving more heat per hour costs efficiency. Still well above old-style window units and most single-stage central ACs. R32 refrigerant pre-charged (about 41 oz). Outdoor unit 102 lbs. Lineset max 82 feet, pre-vacuumed quick-connect included. Cooling 32 to 131°F outdoor, heating 5 to 86°F. 5-year limited warranty. Energy Star and AHRI certified. Good fit for a workshop, an off-grid cabin great room, or a small commercial space where AC is the major load.

EG4 24K Multizone Mini-Split AC/DC Outdoor Unit
The outdoor side of a multi-zone hybrid system. One outdoor unit, up to three indoor heads, total cooling capacity of 24,000 BTU. Mix the head sizes to match how you actually use the rooms: one 12K bedroom and one 12K office, or a 12K and an 18K, or a single 24K head for one big space. Hybrid AC/DC power inputs: 208 to 240 VAC for grid, 100 to 410 VDC for solar. One MPPT port. The unit prioritizes solar during the day and switches to grid when the panels aren't producing. Build the array to hit 2,300W minimum. R32 refrigerant. SEER2 around 22, HSPF2 around 10. Cooling 5 to 131°F outdoor, heating 5 to 86°F outdoor. Outdoor noise 58 to 60 dB(A). 5-year limited warranty. AHRI Certified and Energy Star Certified. Indoor air handlers are sold separately so you spec each zone independently. Pair with the matching line sets (3/8 inch gas valve for the 12K head, 1/2 inch for the 18K and 24K heads) and one comm cable per head. The configurator on this page walks every part.
