FEATURE
This solar controller is used for off-grid photovoltaic (PV) system, such as solar
home system, small power station, etc.
The charging management has been optimized to prolong battery life, and improved
system performance.
The solar controller provides a wide range of Battery type setting: Gel, AGM,
Conventional lead-acid (WET), Calcium, Li Fe PO4, LTO (Lithium Titanium Oxide)
Battery types selection.
Industrial grade MCU control, Pulse width modulated (PWM) technology, high
efficiency operation.
Built in regulator to prevent the battery from being overcharged. Overcharging
occurs when the charge voltage is unregulated. This can result in premature battery
failure.
Come with regulator to prevent the battery from being under charged, in the solar
energy field, battery undercharge always occurs, especially on some Conventional
lead -acid or Calcium batteries; The unit provides an automatic Equalization feature
for deeply drained Conventional lead acid battery or Calcium battery, as well as
provides a cycling automatic Equalizing feature every 28 days.
Protects the battery from discharge at night. Under low light or no light conditions
the solar panel voltage could be less than the battery voltage. The unit contains a
special circuit which prevents current flowing back from the each battery and into
the solar panel.
Colored LED's to easily indicate the operational status and each battery conditions.
Digital LCD to directly display the battery voltage, charging current, charging
capacity, battery type, ambient temperature and faulty codes.
Provides plug-in remote digital display meter (Optional).
Provides external battery temperature sensor (Optional).
Multi charging protections against reverse polarity, short circuit, over temperature,
over voltage, etc.
Surface Mount and weather proof.
Conformal-coated circuit boards and heavy duty terminals apply to hostile
environments.
