Dual-Function Design for Maximum Efficiency

One of the standout features of the SC2000-112 is its bi-directional functionality. It can work as:

• An inverter, converting 12V DC battery power into pure sine wave AC power for running household appliances and electronics.
• A charger, converting AC power from shore power or a generator into DC power to charge your battery bank safely and efficiently.

Advanced 5-Mode Operation

The SC2000-112 features an intelligent 5-mode system that optimizes power flow based on availability and demand:

1. Inverter Mode – Supplies AC power from the battery when external AC power is unavailable.
2. Charger Mode – Recharges the battery when AC power is present.
3. Power Sharing – Manages AC input and battery output to prevent overloading the AC source.
4. Power Generation Mode – Supplies backup power in case of an outage.
5. Power Support Mode – Uses both the battery and AC input to supply additional power when needed.

Smart 3-Stage Charging for Battery Longevity

The SC2000-112 includes a 3-stage smart charging system, designed to optimize battery performance:

• Bulk Charging – Rapidly charges the battery with maximum current.
• Absorption Charging – Slows charging as the battery nears full capacity.
• Float Charging – Maintains the battery at full charge without overcharging.

This intelligent charging process extends the life of your batteries and ensures they remain in peak condition.

Built for Durability & Safety

The Cotek SC2000-112 is designed to operate in extreme conditions, with a wide temperature range (-20°C to 40°C) and multiple safety protections, including:

• Overvoltage and Undervoltage Protection
