· Robust Aluminum Housing

· Epoxy Encapsulated PCB to Prevent Corrosion (IP68)

· Compact Size

· Infrared Remote Control Programming Accessory (CIS-CU)

· Intelligent Timer Functions

· Widely Programmable

· External Temperature Sensor

· 4 Stage Battery Charging (Main, Float, Boost, Equalization)

· Dual load or Dimmable Load Output

· Automatic System Voltage Recognition (12/24 V)

· PV-Systems exposed to extreme weather/environmental conditions (street lights, navigation buoys, etc.) have increased risk for damage in the power electronics. In order to assure reliable battery charge control under such conditions, Phocos developed an encapsulated charge controller (IP68) to prevent corrosion: CIS.

· CIS is an industrial-grade charge controller that is suitable for all practical PV applications. High-quality, 4-stage PWM-charging is combined with amazing features such as: low-voltage disconnect, flexible load timer functions, and a multi-LED system status display. CIS is available in two versions:
• Dual load to independently control two loads.

• Output Dimming to save energy in lighting applications.

· The CIS has no moving parts, switches or buttons. Settings such as battery type, deep discharge thresholds, timers, etc. are made quickly and easily via infrared remote control accessory.

· All devices are connected to the controller by supplied lead wires rather than wire terminals. This feature eliminates the risk of damage from external influences (corrosion, dust, water, bugs, chemicals, physical shock) where components make electrical contact to the controller.

· The extremely compact aluminum housing even allows for mounting CIS inside street light poles. CIS was developed in accordance with well-established Phocos standards incorporating the latest technology, highest-quality and best possible cost/performance ratio.

· The CIS family welcomes new members: the CIS-N and CIS-LED. The CIS-N and CIS-LED series have all the great features of the original CIS series, with the added benefit of negative grounding.

· The CIS-N is designed especially for applications in the gas and oil industry, such as remote monitoring, weather stations, valve controlling, SCADA, and many more.

· The CIS-LED combines three functions in one: Charge controller + flexible timer + LED drivers, making it perfect for users of solar LED lamps and solar LED street lights.

Q:
Yes, a solar controller can be used with a solar air conditioning system. The solar controller will help regulate and optimize the power output from the solar panels, ensuring efficient operation of the air conditioning system.
Q:
Yes, a solar controller can handle different battery types such as lead-acid, lithium-ion, and others. However, it is important to choose a solar controller that is specifically designed to support the specific battery technology being used. Different battery types have varying voltage and charging requirements, so using a compatible solar controller ensures efficient and safe charging for the specific battery type in use.
Q:
Solar panels connected to a solar street light can indeed utilize a solar controller. A solar controller, also referred to as a charge controller, plays a vital role in a solar power system by regulating the flow of electricity from the solar panels to the battery. This regulation prevents both overcharging and over-discharging. In the case of a solar street light, the solar panels generate electricity during the daytime and charge the battery through the assistance of the solar controller. The solar controller guarantees that the battery reaches its optimal capacity and shields it from potential damage due to overcharging. During nighttime, the solar controller efficiently utilizes the battery's power to illuminate the street light. Hence, a solar controller is a crucial component of a solar street light system, ensuring proper charging and effective utilization of solar energy.
Q:
A solar controller handles battery float charging by continuously monitoring the battery voltage and adjusting the charging current accordingly. When the battery reaches its maximum voltage, the solar controller reduces the charging current to a level that maintains the battery at a fully charged state without overcharging it. This float charging mode ensures that the battery remains in optimal condition while preventing any potential damage caused by overcharging.
Q:
A solar controller prevents reverse current flow by utilizing diodes that only allow current to flow in one direction, effectively blocking any reverse current from flowing back into the solar panels or batteries.
Q:
The maximum load power consumption of a solar controller varies depending on the specific model and its specifications. It is important to refer to the product's technical documentation or consult the manufacturer to determine the exact maximum load power consumption.
Q:
A solar controller manages protection against electromagnetic interference through various measures such as the use of shielding materials, grounding techniques, and circuit design. Additionally, it may incorporate filters and surge protection devices to suppress and divert any unwanted electromagnetic signals or disturbances. These measures help ensure the proper functioning and longevity of the solar controller and its connected components in the presence of electromagnetic interference.
Q:
Yes, solar controllers do require regular maintenance. While they are designed to be durable and reliable, regular maintenance is necessary to ensure their optimal performance and longevity. Some common maintenance tasks include cleaning the solar panels to remove any dirt or debris that could reduce their efficiency, inspecting the wiring and connections for any signs of damage or corrosion, and checking the controller's display and settings to ensure they are functioning properly. Additionally, it is recommended to periodically test the system's battery voltage and charge controller settings to ensure they are operating within the desired parameters. Regular maintenance not only helps to identify any potential issues early on but also helps to maximize the efficiency and lifespan of the solar controller.
Q:
A solar controller protects the battery from overcharging by regulating the amount of current flowing from the solar panels to the battery. It constantly monitors the battery voltage and adjusts the charging process accordingly. Once the battery reaches its optimal voltage level, the solar controller limits the charging current to prevent overcharging and potential damage to the battery.
Q:
The specific model and manufacturer determine the maximum power capacity that a solar controller can handle. Solar controllers have the task of regulating the power flow from solar panels to batteries or other loads. They are typically rated in terms of their maximum current handling capacity, which is measured in amps. To calculate the maximum power capacity of a solar controller, multiply the maximum current rating (in amps) by the system voltage (in volts). For instance, if a solar controller has a maximum current rating of 30 amps and the system voltage is 12 volts, the maximum power capacity would be 360 watts (30 amps x 12 volts = 360 watts). It is crucial to select a solar controller that can handle the maximum power capacity of your solar system. Going beyond the maximum power capacity of a solar controller can result in overheating, reduced efficiency, or even damage to the controller. For this reason, it is advisable to refer to the manufacturer's specifications or seek professional advice to ensure that the solar controller is suitable for the power capacity of your specific solar system.
