PWM 20a solar battery charging controller

Regulator, battery charging controller with current from photovoltaic panels PWM 20A 12V 24V

This device connects the solar panel to the battery and ensures its correct charging. Without a regulator, the solar panel would charge the battery with too high a voltage, destroying it. The regulator is also responsible for the proper charging characteristics and maintaining the battery in good condition.

With an LCD display and two USB ports.

Most often used in solar installations in mobile homes, campers and boats.

Automatically recognizes lead-acid and gel batteries.

It has a programmable twilight sensor function.

Programmable functions:

Turning power receivers on and off.

Twilight switch: turning on receivers for a specified time after dark.

Parameters:

Max charging current from panels: 20A

Discharge current: 10A, through the lighting output.

USB output: 5V, max 2A. e.g. for charging a phone.

Max voltage of connected photovoltaic panels: 50V.

DC operating voltages: 12V or 24V

Discharge protection: 11.1V or 22.2V

Overcharge protection: 14.4V or 28, 8V

Load restoration points: 12.5V or 25V

Operating mode: PWM with temperature compensation and periodic battery desulfation function.

12V battery use 18V-20V solar panels

24V battery use 36-40V solar panels

Power panels: 12V= 260W (MAX), 24V= 260W (MAX)

Security:

Anti-short circuit

Open circuit

Over current

Anti overcharge

Against over discharge

Reverse polarity

Additional comments:

This controller can only be used with photovoltaic panels used as a power source. Other power sources cannot be used.

If the LCD display has an error of 0.2V - 0.3V, please don't worry, it is normal.

Old batteries may lose capacity after many charging cycles. If the voltage drops below 8V - the controller will turn off.

The device can ONLY be used indoors (IP30 class). Keep the controller in a cool and ventilated place to maintain good heat dissipation.

PWM design is intended for modules operating in sunlight.

The price is for 1 pc.
