1.0 General Information
1.1 Overview
Thank you for selecting the MPPT solar charge controller.The MPPT is essentially a smart DC to DC converter which has been optimized to harvest maximum energy from the PV array in battery based solar electric systems by using a variety of maximum power point tracking (MPPT) strategies. The controller’s secondary objective is to ensure that the batteries receive a full charge without becoming overcharged. This is accomplished through a four stage charging process. Please take the time to read this operator’s manual and be familiar with the controller.This will help you make full use of the many advantages the MPPT can provide for your PV system.

2.0 General Information
The mounting location is important to the performance and operating life of the controller. The environment must be dry and protected from water ingress. If required, the controller may be installed in a ventilated enclosure with sufficient air flow. Never install the MPPT unit in a sealed enclosure. The controller may be mounted in an enclosure with sealed batteries, but never with vented/ flooded batteries. Battery fumes from vented batteries will corrode and destroy the MPPT circuits. Multiple MPPT can be installed in parallel on the same battery bank to achieve higher charging current. Additional parallel controllers can also be added in the future. Each MPPT must have its own solar array.
CAUTION: Equipment Damage or Risk of Explosion
Never install the MPPT in an enclosure with vented/Flooded batteries. Battery fumes are fl ammable and will corrode and destroy the MPPT circuits.
CAUTION: Equipment Damage
When installing the MPPT in an enclosure, ensure suffi cient ventilation. Installation in a sealed enclosure will lead to over-heating and a decreased product lifetime.
NOTE : Mounting
When mounting the MPPT ,ensure free air through the controller heat sink fins. There should be at least 150mm of clearance above and below the controller to allow for cooling. If mounted in an enclosure, ventilation is highly recommended.

- Q:How do I determine the maximum load output voltage for a solar controller?
- To determine the maximum load output voltage for a solar controller, you need to consider a few factors. 1. Consult the controller's specifications: Check the user manual or product specifications provided by the manufacturer. The maximum load output voltage is usually mentioned in these documents. Look for the "maximum load voltage" or a similar term. 2. Consider the solar panel voltage: The solar controller regulates the voltage from the solar panel to the load. Therefore, the maximum load output voltage should be lower than the maximum voltage that the solar panel can produce. Ensure that the controller's maximum load output voltage is compatible with the solar panel's specifications. 3. Consider the load voltage requirements: Determine the voltage requirements of the devices or appliances you plan to connect to the solar controller. Ensure that the maximum load output voltage of the controller is suitable for powering these devices. If the load voltage requirements are lower than the controller's maximum load output voltage, it should work fine. 4. Safety precautions: It is important to note that exceeding the maximum load output voltage can potentially damage the connected devices or appliances. Therefore, it is crucial to ensure that the load voltage requirements are within the specified range of the solar controller. By considering the controller's specifications, the solar panel voltage, load voltage requirements, and taking necessary safety precautions, you can determine the maximum load output voltage for a solar controller effectively.
- Q:What is the maximum load current for a solar controller?
- The maximum load current for a solar controller is the maximum amount of current that can be safely drawn from the controller to power the connected load. The specific value varies depending on the model and specifications of the solar controller, so it's important to refer to the manufacturer's documentation for the accurate maximum load current rating.
- Q:What is the typical efficiency rating of a solar controller?
- The typical efficiency rating of a solar controller is 95% to 98%.
- Q:The principle of solar controller
- The controller is divided into square matrix (series, parallel) and DC-DC conversion (with MPPT and no MPPT). The principle of withdrawal is the controller to detect the voltage of the battery, when the set value to withdraw from the square: parallel type of Chiang out of the square in parallel to the controller on the dummy load; series directly to the square open circuit. DC-DC conversion type: some parameters will be cured to the controller (usually the charging voltage is set to 55.2V), the square output voltage through the converter fixed to the set value to the battery charge; with MPPT with the above function , But also through the internal MPPT module to track the maximum power point of the matrix so that the matrix has been working in the solar cell's maximum operating point.
- Q:Can a solar controller be used with a solar-powered desalination plant?
- Yes, a solar controller can be used with a solar-powered desalination plant. A solar controller is responsible for regulating the charging and discharging of batteries in a solar power system, ensuring optimal performance and preventing overcharging or damage. In a solar-powered desalination plant, the solar controller would be crucial in managing the power generated by the solar panels to operate the desalination process efficiently.
- Q:How often should a solar controller be replaced?
- A solar controller typically does not need to be replaced very often, as it is a durable component designed to last for many years. However, it is recommended to replace the solar controller every 10-15 years to ensure optimal performance and efficiency of the solar system.
- Q:Can a solar controller be connected to a computer or smartphone for monitoring?
- Yes, a solar controller can be connected to a computer or smartphone for monitoring. Many solar controllers come with built-in communication ports, such as USB or RS-485, that allow them to be connected to a computer or smartphone. This enables users to monitor and control the solar system remotely, check real-time data, adjust settings, and receive notifications or alerts regarding the performance of the solar panels and batteries. Additionally, there are also dedicated mobile apps and software available that provide a user-friendly interface for monitoring and managing solar controllers and other system components.
- Q:What are the safety features of a solar controller?
- The safety features of a solar controller typically include overcharge protection, short-circuit protection, reverse current protection, and over-discharge protection. These features ensure that the solar controller can effectively regulate the charging and discharging of batteries in a solar system, preventing any potential damage or hazards.
- Q:What is the maximum number of battery types supported by a solar controller?
- The maximum number of battery types supported by a solar controller can vary depending on the specific model and its capabilities. Some solar controllers may support only one or a few specific battery types, while others may be able to accommodate a wider range of battery types. It is important to check the specifications and documentation of a particular solar controller to determine the maximum number of battery types it can support.
- Q:What is the maximum charging current a solar controller can provide?
- The maximum charging current a solar controller can provide depends on the specific model and its capabilities. It can range from a few amperes to several tens of amperes, depending on the installation size and requirements.
