EPEVER® MPPT DuoRacer 30A Charge Controller Solar DR3210N for 2 Batteries, 12V/24V Auto Work, PV 100V (DR3210N)

Highlights: The DuoRacer MPPT charge controller is used to charge two batteries (BATT1 and BATT2) at the same time in a solar system. It uses maximum power point tracking technology with ultra-fast tracking speed and a guaranteed tracking efficiency of at least 99.5%. The energy use in the MPPT solar system is increased by 20-30% compared to the PWM charging method. Technical data: BATT1/BATT2 rated voltage 12/24VDC car; rated charging current: 30A; battery input voltage range: 8.5 ~ 32V; max. PV no-load voltage: 100V (at min. Operating environment temperature), 92 V (at 25 °C ambient temperature); rated charging power: 390 W/12 V, 780 W/24 V; MPP voltage range: (battery voltage + 2 V) ~ 72 V; self-consumption: 26 mA/12 V; 15 mA/24 V, 19 mA/12 V, 10 mA/24 V. Energy saving mode Dimensions: 247.2 x 165 x 65.8 mm; weight: 1.4 kg [Protection functions] The controller has protection class IP33, which is water and dustproof. Multiple protection functions, including battery overcharge protection, over-discharge protection and reverse polarity protection of PV and battery, ensure the safety, stability and service life of the solar system. [Support battery] BATT1 type: sealed, gel, flooded, LiFePO4 and Li-NiCoMn (lithium battery cannot be detected automatically, additional accessories from EPEVER such as eBox Wifi/Bluetooth, USB RS485 cable, MT11 display are required for parameter setting of lithium battery); BATT2 (starter battery): lead-acid battery [Optional] RS485 isolated communication interface with 5V 200mA output realizes easy remote monitoring, management and adjustment via PC software, mobile phone app or MT11 display.
