Product Description
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.
