This all-in-one unit combines a powerful pure sine wave inverter, multi-stage battery charger, and automatic AC transfer switch, ensuring uninterrupted power and reliable performance in demanding environments.
Key Features:
- High Surge Power Capacity – Provides up to 5100VA surge power for starting high-draw appliances.
- Smart 4-Stage Battery Charging – Supports Lead-Acid and Lithium batteries with adjustable charging parameters for maximum battery life and efficiency.
- Power Sharing & Generator Support – Automatically reduces battery charging current to prevent AC input overload, allowing the use of smaller generators without tripping breakers.
- Advanced Protection Systems – Includes over/under voltage, short circuit, overload, and temperature protection to ensure long-term safety and reliability.
- Remote Monitoring & System Integration – Supports Cotek CR-20 remote control panel (sold separately) and features RS-232 communication for advanced system integration.
Product Overview
The Cotek SL-3000-112 is engineered to provide a stable and efficient 120V AC power output, making it ideal for powering sensitive electronics, appliances, and off-grid energy solutions. The pure sine wave output ensures compatibility with a wide range of devices, from home appliances to medical equipment.
Smart Battery Charging
This inverter charger features a 4-stage battery charging system (Bulk, Absorption, Final, Equalize) that optimizes battery performance and extends lifespan. The built-in Power Factor Correction (PFC) improves energy efficiency by maximizing real power utilization from the AC input.
Integrated Power Sharing & Generator Compatibility
The Power Sharing function automatically adjusts the charging current to prevent overloading the AC source, allowing users to operate smaller generators or limited shore power sources without tripping circuit breakers. This feature makes it especially useful in RV and marine applications.
Comprehensive Safety and Protection
The SL-3000-112 is equipped with advanced safety features, including:
- Input over/under voltage protection
- Output short circuit and overload protection
- Over-temperature shutdown with auto-restart
These built-in protections ensure the longevity of the inverter charger and safeguard connected devices from electrical faults.
Remote Monitoring & Communication
The SL-3000-112 is compatible with Cotek's CR-20 remote control panel (sold separately), allowing users to monitor and control the inverter charger from a convenient location. Additionally, RS-232 communication enables integration with advanced power management systems for remote diagnostics and system automation.
