That's why a regulator is so crucial to your set up, because it works as a solar controller. Solar regulators act as a go-between to transfer the power generated from 12 volt and 24 volt solar panels to the battery. It ensures the power supplied by your portable solar panels is at the right battery voltage, and protects it from any risk of overcharging. Our regulators feature multi stage charging, including boost, absorption and float - so your battery is charged safely and ready to go when you need it. Regulators work with multiple batteries, including AGM, Standard and Calcium, and they're ideal for permanent installation or for portable systems. Plus, they have multiple levels of protection from overheating and reverse polarity - so they’re perfect for fixed solar panels for 4WD cars, caravans and more.
