Product Features

  With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.
A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.   
A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
The product boasts an optimum MPPT tracking efficiency of up to 99.9%.
Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.
Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.
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 will automatically lower the charging power and bring the charging current to the rated level.
Instantaneous large current startup of capacitive loads is supported.
Automatic recognition of battery voltage is supported.
LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.
Historical data storage function is available, and data can be stored for up to a year.
The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.  
The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.
The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.
Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life.

Protection Functions

  • Waterproof 
Waterproof level: IP32 
  • Input power limiting protection 
When the solar panel power exceeds the rated power, the controller will limit the solar panel power under the rated power so as to prevent excessively large currents from damaging the controller and enter into current-limited charging. 
  • Battery reverse connection protection 
If the battery is reversely connected, the system will simply not operate so as to protect the controller from being burned. 
  • Photovoltaic input side too high voltage protection 
If the voltage on the photovoltaic array input side is too high, the controller will automatically cut off photovoltaic input. 
  • Photovoltaic input side short-circuit protection 
If the photovoltaic input side gets short-circuited, the controller will halt charging, and when the short circuit issue gets cleared, charging will automatically resume. 
  • Photovoltaic input reverse-connection protection
When the photovoltaic array is reversely connected, the controller will not break down, and when the connection problem gets solved, normal operation will resume. 
  • Load overpower protection
When the load power exceeds the rated value, the load will enter into delay protection. 
  • Load short-circuit protection
When the load is short-circuited, the controller can implement protection in a quick and timely manner, and will try to switch on the load again after a time delay. This protection can be carried out up to 5 times a day. Users can also manually address the short circuit problem when finding the load is short-circuited via the abnormality codes on the system data analysis page. 
  • Reverse charging protection at night
This protection function can effectively prevent the battery from discharging through the solar panel at night.
  • TVS lighting protection.
  • Over-temperature protection

What is MPPT solar controller?

MPPT solar controller is designed for solar power system design; Equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provides a powerful control functions.

Features: The controller is characterized by intelligent adjustment of the operating voltage solar panels, solar panel always working at the VA characteristic curve of the maximum power point. More common, solar controller, solar panels for power generation increased utilization of 10-30%!

The controller uses solar panels for intelligent charging of the battery. In the solar panel power than the battery storage capacity, the control system automatically cut off the charge, thus ensuring optimum battery charging features, making full use of electricity.

As the battery can only withstand a certain degree of charge current and float voltage, over current and over-voltage charging the battery will cause serious damage. The controller battery charge grams of real-time detection voltage and charging current, and by controlling the charge current to limit the photovoltaic battery charging voltage and charging current to ensure that both the battery is full, it will not be damaged. To increase of the battery service life.
