MPPT Solar Charge Controller 20A/30A/40A — Intelligent Multifunctional Controller with Automatic Voltage Recognition & Multiple Safety Protections

High-performance MPPT solar charge controller available in 20A, 30A and 40A models. This intelligent, multifunctional unit features automatic voltage recognition and multiple safety protections for reliable solar system operation. It employs advanced double-peak and multi-peak tracking technology so it can still locate the maximum power point when panels are partially shaded or when sections fail, producing multiple peaks on the IV curve. A built-in MPPT algorithm and a mix of tracking methods boost photovoltaic utilization, delivering 15% to 20% higher charging efficiency compared with traditional PWM controllers. The controller achieves MPPT tracking efficiency up to 99.9%, and advanced digital power circuitry raises energy conversion efficiency of the circuit to 98%, while rapidly locking onto the optimal operating point.
