Solar Mini Split That Runs Directly From Solar Panels
The Liniotech 12,000 BTU solar mini split is an AC/DC hybrid air conditioner and heat pump that connects directly to solar panels. Its built-in MPPT controller accepts 80–380V DC from your panels through standard MC4 connectors, so no separate solar inverter or battery is needed. When the sun shines, solar power runs the system. When it doesn’t, 208–240V grid power fills the gap automatically, so you stay comfortable day and night.
Air conditioning is one of the biggest electricity costs in any home. And it peaks on hot, sunny afternoons, exactly when solar panels produce the most power. A solar powered air conditioner puts those two facts together. Instead of sending solar energy through an inverter, the battery and the grid, this DC solar air conditioner uses it right where it’s made. As a result, you cut cooling costs at their source with a simpler, lower-cost setup.
How the Hybrid Solar Air Conditioner Works
On sunny days, your solar panels feed DC power straight into the outdoor unit. The MPPT controller pulls the maximum available power from the panels, and the system runs primarily on solar.
When clouds pass, the hybrid power manager blends solar and grid power automatically, so cooling or heating never drops off.
At night, the system runs on 208–240V grid power like a standard high-efficiency mini split.
There’s no battery to buy, no inverter to install and no switching to manage. The unit simply uses as much free solar power as is available at every moment.
Key Features
Direct DC Solar Input With Built-In MPPT
The outdoor unit contains an integrated MPPT solar controller with over 99.9% tracking efficiency. It accepts 80–380V DC from compatible panels through MC4 connectors. In other words, you wire your panels directly to the air conditioner, with no separate solar equipment in between.
20 SEER Inverter Compressor
A variable-speed inverter compressor adjusts its output to match the room’s demand instead of cycling on and off at full power. It delivers 3,500W (about 12,000 BTU/h) of rated cooling at 833W input, a rated EER of 4.2 W/W and a manufacturer-rated 20 SEER. That means steadier temperatures and lower energy use.
Solar Mini Split Heat Pump for Year-Round Comfort
This is a heat pump as well as an air conditioner. In winter, it moves outdoor heat indoors, delivering 3,800W of rated heating at a COP of 4.2. It heats down to -4°F (-20°C), with automatic defrost and an anti-cold-air function for comfortable warm-ups.
WiFi Control and Quiet Operation
Control temperature, modes and schedules from your smartphone. The indoor unit runs at just 42 dB on high fan speed, quieter than a typical conversation. It also includes Turbo, ECO, Sleep, dehumidify, timer, horizontal swing, self-diagnosis, a filter reminder and a child lock.
R32 Refrigerant
R32 has a much lower global warming potential than the older R410A and transfers heat more efficiently. So you get better performance with a smaller environmental footprint.
Built for Harsh Weather
The system cools in outdoor temperatures up to 140°F (60°C) and heats down to -4°F (-20°C). Anti-corrosion treatment, rain protection, and over-voltage, over-current, over-temperature and leakage protection keep it running season after season.
Solar Panel Requirements
For grid-supported hybrid operation, the manufacturer recommends the following setup for the 12K model:
| Requirement | Specification |
|---|---|
| Number of panels | 2–3 |
| Minimum power per panel | 500W |
| Minimum module efficiency | 20% |
| Panel Vmp | 40V or higher |
| Panel Imp | 13–17A |
| String DC input range | 80–380V |
| Max DC input current | 13A |
| PV cable | 4.0mm² or larger, MC4 connectors |
Solar panels are sold separately. Before ordering, check your panels’ datasheet against these requirements, and confirm the string’s cold-weather open-circuit voltage stays below 380V. Need help choosing panels? Browse our solar panels and contact our team to confirm compatibility before you buy.
How Much Can a Solar Powered Mini Split Save?
Every kilowatt-hour your panels deliver is a kilowatt-hour you don’t buy from the utility. For example, if the system runs 8 daytime hours at about 800W, that’s roughly 6.4kWh per day. With adequate sunshine, solar can supply most or all of that. At a utility rate of $0.16/kWh, that’s about $1 per day, or roughly $30 per month during peak cooling season, for a single room.
Actual savings depend on your climate, sunshine, room size, insulation, electricity rates and how you use the system.
What Size Room Does It Cool?
A 12,000 BTU (1-ton) mini split typically suits rooms of about 450–550 sq ft with standard insulation and 8 ft ceilings. Size up for sunny rooms, kitchens, high ceilings or poor insulation, and size down for shaded, well-insulated spaces. For the most accurate result, have an HVAC contractor perform a load calculation.
Installation Requirements
- Power: a dedicated 208–240V AC circuit for the outdoor unit.
- Solar: 2–3 compatible panels wired to the outdoor unit’s MC4 inputs.
- Refrigerant lines: the line set is not pre-charged, so it requires vacuum evacuation, leak testing and proper charging.
- Professional installation: we strongly recommend a licensed HVAC technician for refrigerant work and an electrician for the AC and solar connections.

Going Fully Off-Grid
The direct-DC solar input is designed to work alongside grid power. For a cabin, shop or home with no grid connection, power the AC side from an off-grid inverter and battery bank instead. Our Liniotech 8kW 120/240V split-phase solar inverter and residential energy storage systems supply the 208–240V power this mini split needs around the clock.

Frequently Asked Questions
What is a solar mini split?
A solar mini split is a ductless air conditioner and heat pump that can run directly on power from solar panels. This Liniotech model has a built-in MPPT controller, so panels connect straight to the outdoor unit with no separate solar inverter.
What is a hybrid solar air conditioner?
A hybrid solar air conditioner runs on both solar DC power and grid AC power. It uses as much solar as is available, then blends in grid power automatically when sunlight drops or at night.
What is a DC solar air conditioner?
A DC solar air conditioner accepts direct current from solar panels without converting it to AC first. That avoids inverter losses and removes the need for extra solar equipment.
Does it need a battery?
No. In standard hybrid operation, solar powers the system during the day and grid power takes over when needed. A battery is only required if you want to run fully off-grid through an inverter.
How many solar panels do I need?
The manufacturer recommends 2–3 panels of at least 500W each for the 12,000 BTU model in a grid-supported setup. Each panel should meet the voltage and current requirements listed in the solar panel section.
Can I plug it into a regular 115V outlet?
No. The 12,000 BTU model requires a dedicated 208–240V AC circuit, the same type used by electric dryers and ranges.
Can it heat as well as cool?
Yes. It’s a heat pump that provides 3,800W of rated heating and works in outdoor temperatures down to -4°F (-20°C).
What size room will a 12,000 BTU mini split cool?
A 12,000 BTU unit typically cools about 450–550 sq ft with standard insulation and ceiling height. Sunny rooms, high ceilings or poor insulation may require a larger unit.
Can I install it myself?
We recommend professional installation. The refrigerant line set is not pre-charged, so it requires evacuation, leak testing and charging with proper HVAC tools, along with safe electrical and solar connections.
What warranty is included?
The Liniotech 12,000 BTU solar mini split includes a 5-year limited warranty.
