Keep Your Garage Cool While Charging Your EV: Why a Solar Mini-Split Is a Smart Upgrade

If you own an electric vehicle (EV), you’ve probably experienced this common Arizona problem: your EV won’t charge in heat. Extreme temperatures in your garage can cause your vehicle’s battery to limit charging or shut it off entirely. But there’s a simple and energy-efficient solution—installing a solar mini-split system.

The Heat Problem: Why Your EV Won’t Charge in Heat

Modern EVs are equipped with thermal protection systems that prevent the battery from charging when temperatures get too high. In Arizona, summer garage temperatures can soar past 110°F, creating a serious issue for EV owners. Not only does this heat make your garage unusable, but it also disrupts overnight charging routines and can shorten your battery’s lifespan over time.

The Solution: A Solar Mini-Split System

A solar mini-split offers both cooling and heating with zero emissions and minimal energy costs when paired with solar panels. These ductless systems are compact, quiet, and perfect for spaces like garages where traditional HVAC doesn’t reach. By maintaining a stable temperature in your garage, you protect your EV battery, make charging more reliable, and create a comfortable workspace or storage area year-round.

Why Go Solar?

Pairing your mini-split with solar power gives you full climate control without increasing your electric bill. Arizona’s abundant sunshine makes it easy to power your solar mini-split throughout the day, especially during peak heat hours when cooling is most needed.
