12 Volt RV Solar Charge Controller

12 Volt RV Solar Charge Controller

Adopting advanced technology mppt solar inverter charge controller

Features of SR-ML2420

• A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.

• The product boasts an optimum MPPT tracking efficiency of up to 99.9%.

• Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.

• Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.

• Instantaneous large current startup of capacitive loads is supported.

• Automatic recognition of battery voltage is supported.

• LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.

• Historical data storage function is available, and data can be stored for up to a year.

• The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.

• The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.

• Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life.
