Offered product is charge controller for solar installations, solar cells. Supports 12V and 24V, the maximum load is 20A. The solar panel, battery and powered device (e.g. lighting) can be connected to the regulator. The product has battery protection against over discharge. If the minimum battery voltage (11.2 V) is exceeded, the regulator will disconnect the power supply to the device. The battery is also protected against overcharging (the solar battery is disconnected when the voltage reaches 14-14.5V) and discharging through the solar panel at night (if the panel has no blocking diode).

The device has a battery level indicator. It is served by the middle LED, which indicates the following states: blinking red - complete discharge (below 11.2 V), lighting red - discharge (11 - 12.2 V), lighting orange - voltage 12.2 - 13, 2 V, lightning green - charging (above 13.2 V). The right LED is for the output device power indicator and the left LED for the solar battery charge indicator.

The regulator also has a working mode switch:

• mode "0" - load off, maximum battery charging speed;
• mode "1" - "3" - the load will be turn on after charging failure after 1 / 2 / 3 hours;
• mode "H" - the load is switched off manually before subsequent mode changes;
• mode "C" - load on, maximum battery charging speed - recommended mode;
• mode "L" - depending on the degree of sunlight of the solar panel;
• mode "D" - debug mode.

Use 12 V batteries for 18 V solar panels. And 24 V batteries for 36 V solar panels!
