Product Overview

The Cotek SC3000-112 is a powerful 3000W pure sine wave inverter/charger designed for off-grid, mobile, and backup power applications. Its advanced bi-directional design allows it to function both as an inverter and a battery charger, ensuring a stable and reliable power supply at all times. When AC power is available, it acts as a charger, efficiently replenishing battery banks. When AC power is lost, it automatically switches to inverter mode, converting DC battery power to clean AC power for connected devices.

This unit is ideal for RVs, boats, off-grid homes, solar power systems, and emergency backup power solutions. With multiple safety certifications and robust construction, it delivers consistent performance in demanding environments.

The SC3000-112 features an intelligent three-stage charging process—Bulk, Absorption, and Float—to optimize battery health and longevity. It also supports a variety of battery chemistries, including GEL, AGM, Flooded, and customizable user-defined settings.

Intelligent Power Management

One of the key advantages of the SC3000-112 is its ability to manage power efficiently. It includes five operating modes that optimize energy usage:

1. Inverter Mode – Converts DC battery power into AC power when no external AC source is available.
2. Charger Mode – Charges connected batteries when an AC power source is present.
3. Power Sharing Mode – Prevents overloading the AC input by automatically adjusting charging current.
4. Power Generation Mode – Supplements AC power by drawing additional power from the battery if needed.
5. Power Support Mode – Works in parallel with an external AC source to provide additional power when demand is high.

These features make the SC3000-112 a smart and efficient solution for both mobile and stationary applications.

Rugged and Reliable

Designed for continuous operation in harsh environments, the SC3000-112 is built to withstand temperature extremes, power surges, and electrical fluctuations. It operates at full load in temperatures ranging from -20°C to 40°C without derating, ensuring consistent performance. Integrated protection features guard against over-voltage, under-voltage, over-temperature, and short circuits.
