• Multiple AC Output Options: Available in 120V and 230V versions to suit different power system requirements.
• Five Operational Modes: Inverter, Charger, Power Sharing, Power Generation, and Power Support modes for optimal energy management.
• High Surge Capacity: Provides up to 4000W peak power to handle high startup loads from appliances such as refrigerators, pumps, and compressors.
• Built-in Safety Protections: Overload, short-circuit, over-temperature, battery reverse polarity, and under-voltage protections ensure safe and reliable operation.
• Compact and Lightweight Design: High power density in a space-saving form factor makes installation easy.
• Wide Input Voltage Range: Handles fluctuations in battery voltage to provide consistent power output.
• Temperature-Compensated Charging: Available with an optional battery temperature sensor to adjust charging based on battery temperature.
• Remote Monitoring Option: Compatible with the CR-20C remote control for convenient monitoring and operation from a distance.

Reliable and Efficient Power Solution

The COTEK SC-2000 is engineered for high efficiency, ensuring minimal energy loss during operation. Thanks to its pure sine wave technology, it produces power identical to that of utility-supplied electricity, making it ideal for delicate electronics, computers, audio systems, and motor-driven appliances.

This inverter charger is perfect for off-grid homes, cabins, marine applications, RVs, and emergency backup systems, where reliable power conversion is essential. Its high surge power capability enables it to handle the startup currents of power-hungry appliances, making it a robust choice for demanding applications.

Intelligent Battery Charging and Management

One of the standout features of the SC-2000 is its intelligent 3-stage battery charging system, which helps maintain battery health over time. By adjusting the charging process based on battery condition and temperature, the SC-2000 maximizes battery life and efficiency. The temperature-compensated charging feature (with an optional sensor) further protects your batteries from overcharging or undercharging in extreme temperatures.

Additionally, the power-sharing feature allows the inverter to work in tandem with an external AC power source (such as a generator or grid connection), preventing power overload and optimizing load distribution.

Versatile and User-Friendly Design

With multiple AC output options available, the SC-2000 comes in 120V and 230V versions to cater to different international standards. The unit’s lightweight yet durable aluminum casing provides excellent heat dissipation, and the built-in cooling fans ensure the inverter remains within safe temperature limits.

For users looking for remote control capabilities, the CR-20C remote control (sold separately) enables convenient monitoring and operation of the inverter charger from a distance, making it ideal for mounting in hard-to-reach locations.

This inverter charger is also built with strict safety certifications, including:

• UL458 with marine supplement (for use in marine applications)
• UL1741 (for renewable energy applications)
• FCC compliance (ensuring low electromagnetic interference)

With these certifications, the SC-2000 meets industry safety standards, making it a trusted choice for off-grid and backup power solutions.
