MPPT Solar Charge Controller
Overview
The HULK Professional Series Solar Controller utilises advanced MPPT control algorithm to maximise the energy from your solar array under any conditions. Compared to the PWM charging method, it can increase the ratio of energy utilisation by 20% - 30%. In high-temperature environments, the controller limits the charging power and current, and reduces charging power functions to ensure stability in high-temperature environments. CE certified with IP33 ingress protection and isolated RS485 design, it offers improved reliability and meets diverse application requirements. Equipped with a self-adaptive three-stage charging mode, this controller prolongs battery lifespan and improves system performance. Comprehensive electronic protection safeguards against overcharge, over-discharge, PV & battery reverse polarity, and more, ensuring a reliable and durable solar system.
