How to Connect a MPPT Solar Charge Controller? | inverter.com

Solar power generation system consists of solar cell, solar charge controller and storage battery (pack). If you want the solar power system to output 220V or 110V AC power, you need to set up a solar inverter. The solar charge controller regulates the charging and discharging of the battery, and controls the solar cell and battery power output to the load according to the power demand of the load, which is the core part of the whole system of photovoltaic energy.

Popular solar charge controllers in the market are mainly pwm charge controller and mppt charge controller. pwm solar charge controller adopts pulse width modulation control mode, which solves the problem of battery dissatisfaction, and the charge conversion efficiency is 75~80%, but the solar panel is not used completely. mppt solar charge controller is an upgraded version of solar power pwm controller. The MPPT charge controller can detect the voltage and current of the solar panels in real time and continuously track the maximum power, so the system always charges the battery with the maximum power. the mppt tracking efficiency is up to 99%, and the power generation efficiency of the whole photovoltaic system reaches 97%.

mppt solar charge controller installation

Besides the wiring, there is something that needs to be considered when installing the mppt solar charge controller.

1. environmental condition

  • the charge controller must be installed on a solid surface.
  • the installation site can be accessible at any time.
  • the charge controller must be installed on a solid surface. location where it can be disassembled at any time.
  • Ambient temperature should be -20℃ ~ 50℃, to ensure optimal working environment.

2. safety distance

respect the safety distance to ensure that other equipment or objects are not within this range, in order to ensure adequate cooling space.
