Industrial Quality Charge Controllers
We want you to have a system that actually works well and lasts for years, but here's the #1 THING YOU NEED TO KNOW
Your Solar panel system is only as good as the charge controller. It's the heart of your system and all controllers are far from equal. Amperage and voltage ratings differ, but more importantly, charging algorithms, protections and advanced features vary greatly between brands.Besides complete system failure when a controller goes bad, the chronic undercharging of your expensive batteries will cause them to fail and need replacement much sooner. Morningstar is an American company and has had over 2.5 million controllers installed in 111 countries over 25+ years. MANY are still in operation today
