Mini Split Multi 4 Zone Gree 21 SEER2 Heat Pump R-32 Condenser, MUL30HP230V1R32AO
This is the model where the Gree R-32 multi platform stops being a room-by-room solution and starts covering whole floor plans. The MUL30HP230V1R32AO is rated 28,400 BTU/h cooling and 30,000 BTU/h heating at 47°F, but its maximum output climbs to 34,100 BTU/h cooling and 40,900 BTU/h heating — a 36 percent heating overhead. Piping doubles the smaller models' reach: 263 feet of total line length, 82 feet to the furthest indoor unit, and 82 feet of elevation difference. Efficiency is 21 SEER2, 13.6 EER2, and 10.0 HSPF2, holding 28,000 BTU/h of heating at 17°F and 27,000 BTU/h at 5°F. Each of up to four zones can be a Gree Livo wall-mount air handler or a Gree ceiling cassette with grille included, and every indoor unit arrives with its own wireless remote. Wi-Fi is factory installed and the allowable combination table is on the submittal. Add your indoor units below.
Reaching Across a Whole Floor Plan
The 82 foot allowance to the furthest indoor unit and 82 feet of vertical separation are what set this condenser apart from the smaller multis, which cap at 66 and 49 feet. A single outdoor unit at grade can now serve indoor units on a second or third floor, or sit at the far corner of a lot behind a fence, without piping becoming the constraint. Combined with 263 feet of total combined length, it opens up floor plans that a shorter-reach condenser simply cannot cover.
The 40,900 BTU/h maximum heating figure also changes the sizing conversation. A heating-dominant project can carry substantially more indoor capacity than the nameplate suggests, so long as the mix appears on the combination table. Calculate each room against its own insulation, glazing, ceiling height, infiltration, and occupancy, then verify the set against the table. Format follows the room: a flush ceiling cassette where the walls are committed to windows or built-ins and a dropped ceiling already exists, a wall-mount head where the install should stay simple and inexpensive.
Ideal for: Two and three story homes where the condenser must stay at grade, larger single-family layouts, homes with a big great room plus bedrooms, additions on the far side of a lot, and heating-dominant projects that need output headroom above the nameplate.
Need more capacity? Step up to the Gree MUL36HP230V1R32AO condenser, which lifts maximum heating output to 51,180 BTU/h and holds full rated capacity down to 5°F, or the 5 Zone MUL42HP230V1R32AO for a fifth zone.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, glazing, ceiling height, ambient conditions, occupancy, and internal heat gain in each zone.

AHRI certification 215218915 applies to this condenser. It holds 77.62 oz of R-32 with 0.2 oz added per foot beyond the pre-charge, measures 40-10/64 x 32-33/64 x 16-52/64 in. at 145.5 lb net, and runs at 58 dB(A). Rated current is 20 A cooling and 21.7 A heating. Cassette selections include the matching decorative grille — GREETF05 on the 9K, 12K and 18K, GREETF06 on the 24K — and each cassette carries an integral condensate pump so it can drain from above the ceiling.

Frequently Asked Questions
Why is rated cooling 28,400 BTU/h rather than 30,000?
The 30,000 figure in the model designation reflects the nominal class and the heating rating at 47°F, which is 30,000 BTU/h. Measured cooling capacity at the 95°F rating condition is 28,400 BTU/h, with a maximum of 34,100 BTU/h. Size cooling loads against 28,400 and treat the rest as headroom.
What does 82 feet of elevation difference allow that 49 feet does not?
It covers genuine multi-story work. Forty-nine feet handles two floors comfortably; 82 feet reaches a third floor, or lets a basement-mounted condenser serve upper levels. Combined with 82 feet to the furthest indoor unit and 263 feet of total length, the condenser can sit wherever it makes sense rather than wherever the piping happens to reach.
Can I put a 24K cassette in the great room and smaller units in bedrooms?
That is exactly the pattern this condenser enables, with maximum heating output reaching 40,900 BTU/h. Note the 24K cassette takes the GREETF06 grille rather than the GREETF05 used on the smaller sizes — both are included with their respective selection. Confirm the specific mix against the combination table on the submittal.
How much refrigerant does a long multi-zone run need?
The condenser ships with 77.62 oz of R-32 pre-charged, and 0.2 oz is added per foot beyond the pre-charge length across the combined run. A layout using most of the 263 foot allowance can need a substantial top-up, so weighing charge on a scale rather than estimating by gauge pressure matters more here than on a short single-zone job.
Does a 2.07 COP at 5°F mean it still saves money in cold weather?
Yes. A COP of 2.07 means the system delivers roughly twice the heat energy it consumes in electricity at 5°F, versus 1.0 for electric resistance heat. Paired with 27,000 BTU/h of actual output at that temperature and rated operation to -22°F, it remains a credible heat source well below freezing.
Is the outdoor unit noticeably louder than the smaller multi condensers?
Somewhat — 58 dB(A) versus 55 on the 24,000 BTU model and 51 on the two-zone. It is comparable to a conventional residential condenser. At 145.5 lb it also needs a properly bedded level pad, and placement away from bedroom windows and property lines is worth planning at this size.
