FAQ on EG4 Solar Mini Split

How much solar do I need to run a mini split?

It’s tough to pinpoint without specifics, but here’s a simplified breakdown. 

For an 18,000 BTU unit with a SEER rating of 20, you’re looking at about 900W of power usage. Over 12 hours, that’s 10,800Wh per day. With optimal sunlight (let’s say 5 hours of good sun), you’d need around 2,160W of solar power. 

To cover days with poor weather and keep your A/C running 24 hours, aim for 10,800Wh of battery capacity. As for the inverter, choose one that can handle your unit’s peak load and about three times its average consumption for efficiency. For a more personalized calculation, check tools like a sun calculator and consider monitoring your system’s energy use directly.

Is a mini split energy efficient?

Absolutely! Mini-splits that earn the ENERGY STAR label are proven to be highly efficient. They work by transferring heat rather than generating it from scratch, using up to 60% less energy compared to traditional electric heating systems. This makes them a smart choice for both your wallet and the environment.

Do mini-splits use a lot of electricity?

The electricity usage of a mini split varies. Typically, it ranges between 4 to 12 kWh per day but can differ based on how frequently you use it, the unit’s size, and local weather conditions. Mini-splits are designed for efficiency, especially models with the ENERGY STAR label, so they’re still a cost-effective choice compared to conventional heating and cooling methods.

Can a Solar Generator Run A Mini Split?

Yes, a solar generator can power a mini-split, making your setup even more eco-friendly. The key is matching the generator’s output to your mini split’s energy requirements. For an in-depth look at how to achieve this and to find the right solar-powered setup for your needs, visiting pages like Jackery’s guide on solar-powered mini splits offers a wealth of information.

Now, I wouldn’t recommend powering your solar mini-split system on a solar generator. A solar generator does have limited solar power which limits the time needed to power a solar split system. I would recommend buying separate solar panels just for your solar mini-split.
