Dear users: Contents 1. Product introduction 1.1 Product overview Thank you for choosing our products! 1.2 Product features 1.3 Description on appearance and interface 2. Introduction to maximum power tracking technology 3. Technical parameters 4. Charging 4.1 Charging of lead-acid battery Safety Instructions 4.2 Charging of lithium battery 5.
Adopt high-quality aluminum radiator and high-temperature derating treatment to ensure reliable and cannot obtain the maximum energy of the solar panel. Instead, the solar controller with MPPT can efficient operation in various operating conditions.
The MPPT controller can overcome the problem and adjust the input voltage and current of the 3. Technical parameters solar panel in real time to reach the maximum input power. Moreover, compared with the traditional PWM controller, it can exert the maximum power of the solar battery to provide a larger charging...
Select such battery types as SLD/FLD/GEL/USE, and select the appropriate system voltage. not connected, the default temperature is 25°C; As shown in Fig. 4-1, the charging stages of lead-acid battery are: MPPT charging, constant voltage charging (equalizing/ boost/floating charging), and current-limiting charging.The constant voltage charging is divided into three stages: 2).
7. Menu 1) Alternative display between (voltage/power) and (current/power) on the main menu every 10s. 2) Short press the key to browse the menu. If there is no key operation for 5s, it will [SELECT] automatically return to the main menu. 3) Long press [ENTER] for 3s on any interface to enter the parameter setting page.

System alarms 13.Common problems and solutions System alarms Meaning Phenomenon Troubleshooting Description No action Check whether the battery and solar panel are properly Normal system LCD screen does not light up connected and whether the LCD connection cable has a poor connection Turn off...
15. Protection Functions When connecting the system, the output voltage of the components may exceed the human body safety voltage, therefore, use insulated tools and keep your hands dry. The battery terminals on the controller can be connected either to a single battery or a battery pack. Over-temperature protection of device The subsequent instructions are for a single battery, but they are also applicable to systems with a When the internal temperature of the controller exceeds the set value, the charging power will be...
