What is the Best Solar Powered Mini Split Unit
Mini split units are ideal for an HVAC systems that can work with solar panels.

They are widely used with home additions, garages, sheds and many other locations.

While mainly residential they can also be used with RVs, campers, and trailers.

They are very efficient units that have a low-power usage and are built to last many years.

Mini split units are also the best HVAC systems to use with solar panels.

Why Is a Mini Split Ideal for Solar Panels?

  • Very efficient units with less power usage.
  • Small and compact compared to traditional HVAC units.
  • DIY installation kits.

Mini split units draw less power to start and operate compared to a traditional HVAC system.

Since they use less power to operate they can be run from solar panels and batteries.

A system can also be installed by a DIY type person with many different kits available.

What to Look for in a Mini Split Solar Panel Combination?
Besides the build of a system, the main thing to look for with solar and mini split units is the SEER rating.

Units can vary how efficient they are and rated by a SEER rating.

The higher the SEER rating the less power a unit will need to run.

A minimum of a 23 SEER rating for a mini split and solar panels but higher the better.

There are high SEER rated units up to 25-35 SEER.

Heat Pump vs Air Conditioner Only
A heat pump mini split can heat in the winter and cool in the summer which is ideal in most scenarios.

Most mini split units are heat pumps but be sure if the can heat since some only run in air conditioner mode.

Heat pump unit have what is called a reversing valve that will let it heat or cool.

How To Install a Mini Split with Solar Panels
A mini split has three main parts the inside wall unit, outside condenser, and line-set.

The outside condenser is located outside and dissipates hot or cold air away.

The inside wall unit mounts on a wall and blows air into a room.

A line-set is two cooper lines that transfers refrigerant between the two units which transfer hot or cold air.

The outside condenser needs to be placed on a solid surface.

Electrical will also be needed to run to the unit which will vary on the systems power requirements.

Every install will be different and need to fit the scenario.

How Many Solar Panels are Needed to Run a Mini Split?
This will vary on the unit bought since every units power requirements will be different.

Many high-efficiency mini split unit needs 550 to 1000 Watts to operate.

A mini split will have a peak power consumption rating which will need to be supplied.

For example, if a unit has a peak power requirement of 990 Watts this will need to be supplied.

In this example, five 200 Watt solar panels can be used with a 2000 Watt inverter and a battery to supply power.

There are many solar panels, inverters, and battery combinations.

So What is the Best Solar Powered Mini Split?
There is no single best set up with many different opinions.

Many units available that can be used in combination with solar panels, power inverters, and batteries.

There are a few systems that are set up to work with solar panels and use DC voltage.

Many people use a standard mini split unit and use an inverter to supply the AC voltage needed.

There are many good units available with some of our favorite picks below.

As always be sure to read the reviews on Amazon, forums, here, or elsewhere to be sure a unit is a good fit for you.
