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 does a solar controller prevent damage to the solar panels during low voltage conditions?
- A solar controller, also known as a charge controller, is an essential component in a solar power system that helps prevent damage to the solar panels during low voltage conditions. During low voltage conditions, such as when the solar panels are not receiving sufficient sunlight or when the battery is fully charged, the voltage output from the solar panels can drop significantly. This low voltage condition can potentially damage the solar panels and reduce their overall lifespan. To prevent such damage, a solar controller regulates the voltage and current flowing into the battery or the connected load. When the voltage from the solar panels drops below a certain threshold, the solar controller intervenes and adjusts the charging parameters accordingly. One of the primary functions of a solar controller is to ensure that the battery is not overcharged, as this can lead to damage or reduced performance. It monitors the battery's state of charge and adjusts the charging current to maintain a safe voltage level. During low voltage conditions, the solar controller may reduce or interrupt the charging current to prevent overcharging and potential damage to the solar panels. Additionally, a solar controller also protects the solar panels from reverse current flow. At night or during periods of low sunlight, the power generated by the solar panels can flow back into the panels, causing damage. The solar controller prevents this reverse current flow by blocking the current from flowing in the wrong direction, thus protecting the panels from damage. Overall, a solar controller plays a crucial role in safeguarding the solar panels during low voltage conditions. By regulating the voltage and current, monitoring the battery's state of charge, and preventing reverse current flow, the solar controller ensures optimal performance and longevity of the solar panels in varying environmental conditions.
- Q: Can a solar controller be used in a commercial solar system?
- Yes, a solar controller can be used in a commercial solar system. Solar controllers are essential components that regulate the flow of electricity between solar panels and batteries or the grid. They help optimize power production, protect batteries from overcharging, and ensure efficient operation of the solar system. Whether it is a residential or commercial solar system, a solar controller plays a crucial role in maintaining the system's performance and longevity.
- Q: Can a solar controller be connected to multiple solar panels?
- Yes, a solar controller can be connected to multiple solar panels. By connecting multiple solar panels in parallel or series, the solar controller can effectively manage and regulate the charging of the combined solar energy generated by all the panels.
- Q: Can a solar controller handle power fluctuations from the charge controller?
- Yes, a solar controller is designed to handle power fluctuations from the charge controller. It acts as a regulator to stabilize and control the flow of power coming from the charge controller, ensuring a consistent and reliable energy supply to the connected devices or battery.
- Q: How long do solar controllers typically last?
- Solar controllers typically last for around 10 to 15 years, depending on the quality of the controller and how well it is maintained.
- Q: What is the maximum input current for a solar controller with an LCD display?
- The maximum input current for a solar controller with an LCD display depends on the specific model and manufacturer. It is important to consult the product specifications or user manual to determine the maximum input current rating for a specific solar controller with an LCD display.
- Q: What is the maximum number of communication protocols supported by a solar controller?
- The maximum number of communication protocols supported by a solar controller can vary depending on the specific model and manufacturer. Some solar controllers may support only one or a few communication protocols, while others may be compatible with multiple protocols such as RS485, Modbus, CAN, or Ethernet. It is important to check the specifications of a particular solar controller to determine the maximum number of supported communication protocols.
- Q: How does a solar controller handle battery overvoltage disconnect recovery?
- A solar controller typically handles battery overvoltage disconnect recovery by automatically reducing or stopping the charging process when the battery voltage exceeds a predetermined threshold. This helps prevent any further overcharging or damage to the battery. Once the battery voltage drops back to a safe level, the solar controller resumes the charging process to maintain the battery's optimal charge.
- Q: Are solar controllers necessary for all solar panel installations?
- Solar controllers, also known as charge controllers, are not necessary for all solar panel installations. The need for a solar controller depends on the specific characteristics of the solar panels being used and the overall system design. Solar controllers are primarily used in off-grid solar panel installations, where the panels are not connected to the electrical grid. In these setups, a solar controller is crucial as it regulates the flow of electricity from the panels to the battery storage system. It prevents overcharging by monitoring the battery's state of charge and temperature, ensuring the batteries are maintained at optimal levels and protected from damage. On the other hand, grid-tied solar panel installations, where the panels are connected to the electrical grid, typically do not require solar controllers. In these setups, the electricity generated by the panels is immediately fed into the grid, and there is no need for battery storage. The grid acts as a storage system, eliminating the need for a charge controller to regulate the flow of electricity. However, it is important to note that some grid-tied systems may still incorporate a solar controller if they have additional components like batteries or if they are designed to operate in areas with unreliable grid connection. In such cases, the solar controller would be responsible for managing the battery charging and discharging process, ensuring the system's efficiency and longevity. Ultimately, the necessity of a solar controller depends on the specific requirements and design of the solar panel installation. It is always recommended to consult with a professional solar installer or engineer to determine whether a solar controller is necessary for a particular system.
- Q: Is it necessary to have a solar controller for every solar panel?
- No, it is not necessary to have a solar controller for every solar panel. A solar controller is typically used to regulate the charging and discharging of batteries in a solar power system. If the solar panels are directly connected to the grid or are not being used to charge batteries, a solar controller may not be needed. However, if batteries are being used to store the solar energy, a solar controller is recommended to ensure proper charging and to protect the batteries from overcharging or damage.
