I. PRODUCT INTRODUCTION

Solar controller is control device which can control solar panel and transform solar energy into electricity then store to the battery bank. Solar controller is the most important part in off-grid system, whose performance has much effect on life expectancy and operation of the whole system, especially the battery expectancy. Or battery service life will be shortened by over charge or over discharge.

II. PERFORMANCE FEATURES

Superior military-grade components to ensure the product stability.

Perfect protection function, thus the system has higher reliability.

Check and set all operation parameters as requirement from LCD display.

PWM stepless unload mode, which burn the excess power into Dump load, making the battery charging in best status.

III. APPLICATION AREAS

Standalone Photovoltaic power station

Standalone Domestic household photovoltaic power system

Mobil communication base stations, expressway and other non-residential regions.

Coastal islands, remote mountainous, border posts for regions shortage of or without electricity.

Government demonstration projects, landscape lighting project etc.

Q:Are there any energy-saving features in a solar controller?: Solar controllers typically have various energy-saving features. One notable feature is their ability to regulate and optimize battery charging in the solar system. This ensures efficient charging, preventing overcharging and extending battery lifespan. Additionally, solar controllers often include a low voltage disconnect (LVD) feature. When the battery voltage drops below a certain level, the load automatically disconnects to prevent excessive discharge, which can harm the batteries. Some advanced solar controllers even have maximum power point tracking (MPPT) technology. This technology continuously adjusts voltage and current to match ideal operating conditions, maximizing energy harvested from the solar panels. As a result, the overall energy efficiency of the solar system is significantly improved.

Q:Solar controller 10a, a represents what: A, represents the current. Indicates the current that is allowed to pass during operation of the controller.

Q:Can a solar controller be used in a solar-powered Mars colonization mission?: Yes, a solar controller can be used in a solar-powered Mars colonization mission. A solar controller is an essential component that regulates the voltage and current flowing from the solar panels to the batteries, ensuring proper charging and preventing overcharging. It plays a crucial role in maintaining the efficiency and longevity of the solar power system, which would be vital for sustaining power supply in a Mars colonization mission where solar energy is the primary source.

Q:What is the maximum discharge current for a solar controller?: The maximum discharge current for a solar controller typically depends on the specific model and capacity of the controller. It can range from a few amps to several hundred amps, depending on the design and intended use of the controller.

Q:What is the maximum cable size that can be used between the solar panels and the load?: The size of the cable that can be used between the solar panels and the load depends on several factors, including the distance between the panels and the load, the cable's current carrying capacity, and the permissible voltage drop. In instances where the distance is shorter and the current requirements are lower, smaller cable sizes may suffice. Conversely, for longer distances or higher current loads, larger cable sizes are essential to minimize voltage drop and ensure efficient power transmission. To determine the maximum cable size that can be used, it is crucial to refer to the manufacturer's specifications and guidelines for both the solar panels and the load. Additionally, local electrical codes and regulations may offer further guidance on cable sizing requirements.

Q:What is the maximum input power that a solar controller can handle?: The maximum input power that a solar controller can handle varies depending on the specific controller model and its specifications. It can range from a few hundred watts to several kilowatts, depending on factors such as the controller's design, size, and intended application.

Q:How does a solar controller handle the protection against high voltage transients?: A solar controller handles the protection against high voltage transients by employing various protective measures. These measures include surge protection devices, voltage clamping circuits, and overvoltage protection modules. These components work together to detect and limit the voltage spikes that may occur in the solar panel system. By diverting or suppressing the excess voltage, the solar controller ensures that the system and its connected devices are safeguarded from potential damage caused by high voltage transients.

Q:Can a solar controller be used with a solar-powered hydrogen production system?: Yes, a solar controller can be used with a solar-powered hydrogen production system. The solar controller is responsible for regulating and optimizing the flow of electricity from the solar panels to the hydrogen production system, ensuring efficient and reliable operation.

Q:What is the maximum charging efficiency for a solar controller?: The maximum charging efficiency for a solar controller is typically around 98%.

Q:How does a solar controller handle load control for powering other devices?: A solar controller manages load control by regulating the flow of electricity from the solar panels to power other devices. It ensures that the power generated by the panels is distributed efficiently and effectively to meet the energy demands of the connected devices, while also protecting the battery bank from overcharging or discharging. The controller monitors the battery voltage and adjusts the charge/discharge cycle accordingly, ensuring optimal utilization of the available solar energy while preventing any damage to the system.
