MPPT Solar Charge Controller Input 50V for Gel Lithium Battery Household

● Built-in maximum power point tracking algorithm can significantly improve the power utilization efficiency of photovoltaic systems, and the charging efficiency is 15%~20% higher than that of traditional for PWM methods.

● The product's optimal MPPT tracking efficiency is as high as 99.9%.

◆ Advanced digital power technology makes the circuit's power conversion efficiency as high as 98%.

● The controller has a current limit. Charging mode. When the power of the solar panel exceeds a certain level and the charging current is greater than the rated current, the controller automatically reduces the charging power to make the charging current reach the rated level.

● Supports instantaneous start of capacitive loads with large currents.

◆ Supports automatic identification of battery voltage.

◆ With fault LCD display, users can easily identify system faults.

◆ The controller has a built-in over-temperature protection mechanism. When the temperature exceeds the set value, the charging current decreases linearly in proportion to the temperature, and stops discharging, suppressing the temperature rise of the controller, and effectively the controller from overheating and damage.

◆ With temperature compensation function, the controller can automatically adjust the charging and discharging parameters to extend battery life.

◆ 0V lithium-ion battery charging function.

◆ Adopts metal shell for better heat dissipation performance.

◆ The solar panel charging input voltage is high, which reduces the specifications of the solar connection cable and reduces the system cost.

◆ It can support the optional RS485 protocol model to meet the communication needs of different occasions.

Protection function introduction

◆ Waterproof

Waterproof level: IP21

◆ Input power limit protection

When the power of the solar panel exceeds the rated power, the controller will limit the power of the solar panel to below the rated power to prevent excessive current from damaging the controller and entering the current limiting load.

◆ Photovoltaic input side voltage over-high protection

If the voltage on the photovoltaic array input side is too high, the controller will automatically cut off the photovoltaic input.

◆ Photovoltaic input lateral short circuit protection

If the photovoltaic input side is short-circuited, the controller will stop charging, and charging will automatically resume when the short-circuit problem is cleared.

◆ Photovoltaic input reverse connection protection

When the photovoltaic array is reversed, the controller will not be damaged, and normal operation will be restored when the connection problem is solved

◆ Charging short circuit protection

Protect the charging short circuit in a timely and fast manner, and automatically open and try to charge after a certain time delay. When a charging short circuit occurs, the charging short circuit can be manually cleared.

◆ Nighttime reverse charging protection

This protection function can effectively prevent the battery from discharging through the solar panel at night.

◆TVS protection.

◆Over-temperature protection.

When the controller temperature exceeds the set value, the charging power will be reduced or charging will be stopped.
