MPPT Solar Controller 20A

MPPT Solar Controller 20A - with Overheat Protection Mechanism and Automatic Charging Voltage Regulation

MPPT Solar Controller 20A

Features

A solar charge controller, or a solar regulator, is a solar battery charger connected between the solar panels and the battery. Its job is to regulate the battery charging process and ensure it is charged correctly, or more importantly, not over-charged.

• The advanced multi-peak tracking technology: When the solar panel is shadowed or part of it breaks down, the I-V curve will have multiple peaks. However, the controller is still able to track the maximum power point accurately.
• The maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems. The charging efficiency is 15 per cent to 20 per cent higher than the conventional PWM method.
• Automatic charging voltage regulation function: When there is a battery open circuit or lithium battery BMS overcharge protection, the controller battery terminal will output at the rated charging voltage value.
• MPPT tracking efficiency is up to 99.9 per cent.
• Advanced digital power technology raises the circuit energy conversion efficiency to 98 percent.
• It supports charging lithium batteries, gel batteries, sealed batteries and abroach batteries.
• The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller automatically lowers the charging power and brings the charging current to the rated level.
• Support automatic identification of lead-acid battery voltage.
• The controller can be connected with LCD screen or Bluetooth module so that users can not only check operating data and status, but also modify the controller parameters.
• The controller is available for standard Modbus protocol and meets different communication needs.
• The controller has an overheat protection mechanism. When the temperature exceeds the set value, the charging current will decline in linear proportion and discharging will be shut off so as to curb the temperature rise of the controller and keep the controller from being damaged by overheat.
• Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters to extend the lifespan of the battery.
• Solar panel short circuit protection, battery open circuit protection and TVS lightning protection, etc.
