Hulk 4×4 20A MPPT Solar Charge Controller

Hulk 4×4 20A MPPT Solar Charge Controller, 1 Year Warranty. 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. Features: 100% charging and discharging in the working temperature range High-quality components from ST or IR for extended service life Advanced Ultra-Fast Tracking MPPT technology ensures up to 99.5% tracking efficiency Maximum DC/DC transfer efficiency up to 98.5%; full load efficiency up to 97.2% Accurate recognition and tracking of multi-peaks maximum power point Wide MPP operating voltage range Supports lead-acid and lithium batteries with adjustable voltage parameters Programmable temperature compensation Limit charging power and current overrated value Real-time energy statistics Overheating power reduction function Multiple load work modes Isolated RS485 with 5V/200mA protected output for no power devices, with Modbus protocol Supports monitoring and parameter setting via app or PC software
