1. Solar off-grid power generation system solutions

Application:

The solar off-grid power generation system uses photovoltaic modules to collect and process electrical energy and store it in the battery pack, and then draw electricity from the battery pack when it is used. It is mainly used in remote and remote rural areas, pastoral areas, islands, deserts, and border guard posts that are difficult to cover by the public power grid to provide basic living electricity for lighting, TV, radio, etc., as well as communication base stations, highway monitoring, meteorological stations and other fields.

Features of solar controller:

◆ Advanced dual-wave or multi-peak tracking technology, when the solar panels are shaded or some of the solar panels are damaged, multiple peaks will appear on the I-V curve, and the controller can still accurately track the power point.
◆ The built-in power tracking algorithm can significantly improve the energy utilization efficiency of the photovoltaic system, which is about 15%~20% higher than the traditional PWM charging efficiency.
◆ The combination of various tracking algorithms can accurately track the appropriate working point of the I-V curve in a very short time.
◆ MPPT tracking efficiency can be as high as 99.9%.
◆ Using advanced digital power technology, the circuit energy conversion efficiency is as high as 98%.
◆ Support charging procedures for different types of batteries such as gel batteries, sealed batteries, open batteries, and lithium batteries①
◆ With current-limiting charging mode, when the power of the battery board is too large and the charging current is greater than the rated current, the controller will automatically reduce the charging power to make it work at the rated charging current.
◆ It can support instantaneous high-current startup of capacitive load.
◆ Support automatic identification of battery voltage.
◆ With fault LED indication, buzzer alarm, and LCD display abnormal information, it is convenient for users to determine system faults.
◆ Support historical data storage, the storage time is up to 5 years.
◆ Equipped with LCD screen display function, you can check the operation data and status of the equipment, and support the change of controller parameters.
◆ Support standard Modbus protocol to meet the communication needs of different occasions.
◆ Built-in over-temperature protection mechanism, when the temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of the controller and preventing the controller from being damaged by high temperature.
◆ With the function of external battery voltage sampling, the external battery voltage sampling can make the battery sampling not affected by the line loss and make the control parameters more accurate.
◆ With temperature compensation function, it can automatically adjust the charging and discharging parameters to improve the service life of the battery.
◆ TVS lightning protection
