MPPT Solar Charge Controller 20A/30A/40A — Intelligent, Multifunctional with Automatic Voltage Recognition, Easy to Use

This MPPT controller (available in 20A, 30A or 40A versions) uses double-peak or multi-peak tracking technology to reliably find the true maximum power point even when a panel is partially shaded or damaged, producing multiple peaks on the IV curve.

The built-in maximum power point tracking algorithm, together with a combination of multiple tracking algorithms, locks onto the optimal operating point on the IV curve in a very short time. Compared with traditional PWM controllers, charging efficiency is increased by 15% to 20%.

MPPT tracking efficiency can reach up to 99.9%, and advanced digital power technology enables the circuit’s energy conversion efficiency to be up to 98%. Features include automatic voltage recognition and intelligent, multifunctional control for straightforward operation.
