Solar Friendly Air Conditioners

If you wish to add air conditioning to a structure while powering it with solar power, this is what you need:

High Efficiency Mini-Split DC Inverter Heat Pump System.
SEER Rating of 18-27 is preferred. Do not use traditional air conditioners if you plan to run it off solar. You will have a bad time.
A well insulated structure.
Before you install any HVAC system, you need to seal doors/windows and use double paned windows. If you do not, using solar to heat or cool your structure will be nearly impossible.
A large solar power system.
If you plan to heat/cool your structure, you will need a ton of power! Build it as large as you can afford.

EG4: A Heat Pump that Anyone can Install!

This is hands down my favorite mini split on the market. Not only is it the easiest to install, but it has a fantastic warranty and efficiency.

EG4 uses pre-charged lines so you can install it safely without an HVAC tech. You can install this with basic tools in a couple hours!

Reverse cycle heat pump, so it is an air conditioner during summer, and a high efficiency heater during the winter! And a dehumidification setting that works great.
Runs on 120V AC: 9,000 or 12,000 BTU of cooling and heating, for rooms up to 450 to 650 sq ft
Comes with everything you need to install it. All you need is a few wrenches and drill attachments that you can buy from any local hardware store. This is the only heat pump on the market that anyone can install!

EG4 Mini-Split with Pre-Charged Lines

120V mini split and heat pump with R32 coolant and pre-charged 16.4 ft lines. Available in 9,000 or 12,000 BTU.

What Comes in the EG4 Kit

Everything ships in one kit, so you are not hunting for extra parts. It runs in outdoor temperatures from 14 to 136°F and comes with a 5-year EG4 warranty.

Dirt Cheap Mini Split

When filming my mini split video series, I found that the cheap models have the same compressor and components as the more expensive ones! These require a vacuum pump to hook up, and it takes an extra hour or two, but you can save some serious money with this method!

Diamante Essenza

What I currently use to cool and heat my 1000 Sq Ft workshop is a 36,000 BTU Pioneer Mini Split with DC Inverter Technology.
Not easy to install, and not as efficient as my Mr. Cool mini split, but it does work well. If you have an HVAC tech on hand, go for this unit. If you are doing a DIY install, use Mr. Cool instead.
If I were to choose a mini split for my shop, I would have gone with Mr. Cool or the new EG4 heat pump up above. They are amazing.
