Solar charge controller AZO Digital MPPT 12/24 - 20A with LCD display

Index: AZO-12981 EAN: 5905279203891

It allows charging of the batteries ensuring the proper current characteristics and protecting against overcharging or deep overcharging thus increasing the battery life in the solar panel/battery system. What distinguishes MPPT controllers from PWM is the study of the maximum power point of the panel, thereby accelerating the charging of batteries by 20-30%.

Product description: AZO Digital MPPT 12 / 24 - 20 A solar charge controller with LCD display

Improved version of the PWM controllers. Allows you to charge batteries, ensuring the proper current characteristics and protecting against overcharging or deep overcharging, thus increasing the battery life in the system Solar Panel / Battery. After exceeding a critical voltage, the regulator disconnects the source of energy consumption, the same is with a fully charged battery - the regulator then disconnects the power from the photovoltaic panels. The device works with gel, AGM batteries with voltage of 12 V and 24 V. What distinguishes MPPT controllers from PWM is the study of the maximum power point of the panel, thereby accelerating the charging of batteries by 20-30%. This function is ideal for the climatic conditions of our country. In addition, MPPT-20Dversion is equipped withan LCD display showing the operating parameters of the regulator.

  1. MENU button - responsible for changing the content of the display and after a long holding (5 seconds) to enter the editing mode of the selected parameter
  2. LOAD button - on/off switch of the DC load circuit. One short pressing - switching on the circuit, one short pressing - switching off the circuit
  3. Display - informs about the current operating parameters
  4. Up arrow button - changing a displayed parameter in the menu and changing a given value in the edit mode
  5. Down arrow key - changing the displayed parameter in the menu and changing the given value in the edit mode
  6. Panel connector - positive and negative poles used to connect the solar panel
  7. Battery connector - positive and negative terminals used to connect the battery (12V or 24)
  8. Load connector (output) - positive and negative terminals used to connect the load (12V or 24V depending on the connected battery)
