{"product_id":"solarni-regulator-mppt-carspa-mh-r2420-12-24v-20a","title":"Solar controller MPPT Carspa MH-R2420, 12\/24V, 20A","description":"Professional MPPT controller designed for charging 12 \/ 24 V lead-acid and LiFePO4 batteries with solar energy. Compared to cheaper PWM type loss regulators, these regulators achieve much higher efficiency (up to 98%) and ensure maximum energy yield from solar panels. AGM, GEL and LiFePO4 sealed batteries are supported, the voltage is detected automatically. A comprehensive LCD display shows  voltage of the solar panels and the battery, charging current, state of charge, load current, temperature or error code in case of a fault. At the same time, a thermocouple for charging temperature compensation is included. The connected DC load can be switched manually by the controller or simply programmed (e.g. twilight switching with a timer). A sophisticated protection system prevents the controller, solar panels and battery from damage or incorrect connection.\u003cbr\/\u003e\u003cbr\/\u003e- MPPT technology for monitoring the maximum performance of the panels\u003cbr\/\u003e- adaptive multi-stage battery charging\u003cbr\/\u003e- automatic detection of 12 \/ 24 V\u003cbr\/\u003e- support for lead AGM \/ GEL and LiFePO4 batteries\u003cbr\/\u003e- advanced battery and panel protection system for higher safety\u003cbr\/\u003e- TVS lightning protection\u003cbr\/\u003e- clear LCD display, LED indicators of operating status\u003cbr\/\u003e- programmable DC load switching\u003cbr\/\u003e- absolutely silent passive cooling\u003cbr\/\u003e- sensor for charging temperature compensation\u003cbr\/\u003e- communication port for monitoring\u003cbr\/\u003e\u003cbr\/\u003e\u003cbr\/\u003eTechnical parameters\u003cbr\/\u003e\u003cbr\/\u003eBattery voltage: 12 \/ 24 V (auto detection \/ manual setting)\u003cbr\/\u003eMax. panel power: 260 W \/ 12 V, 520 W \/ 24 V\u003cbr\/\u003eMax. panel voltage (Voc): 100 V (25°C), 90 V (-25°C)\u003cbr\/\u003eMax. regulator current: 20 A\u003cbr\/\u003eBattery voltage range: 9 to 35 V\u003cbr\/\u003eBattery type: AGM, GEL, Sealed, LiFePO4, user defined\u003cbr\/\u003eMPPT voltage range: battery voltage +2 V to 75 V\u003cbr\/\u003eVoltage conversion efficiency: 98 %\u003cbr\/\u003eMPPT tracking efficiency: \u003e 99 %\u003cbr\/\u003eProtection against: PV and battery overvoltage, PV overpower, overcurrent, total battery discharge, battery overcharge, short circuit, reverse polarity, DC load output overload, lightning strike (TVS)\u003cbr\/\u003eMax. capacitive load: 10,000 uF\u003cbr\/\u003eMax.
