Unmatched Performance & Intelligent Power Management

The Cotek SC-3000 inverter charger is designed for users who need a powerful, reliable, and intelligent power solution. It features a bi-directional design, meaning it converts DC battery power into AC power while also functioning as an efficient battery charger when AC input is available. This makes it an ideal choice for off-grid systems, RVs, boats, and emergency backup power applications.

With five distinct operating modes, the SC-3000 optimizes power usage based on real-time demand:

1. Inverter Mode – Converts DC battery power into stable, pure sine wave AC output.
2. Charger Mode – Uses available AC power to charge the battery bank with up to 150A current.
3. Power Sharing Mode – Balances power load between inverter and AC source to prevent system overload.
4. Power Generation Mode – Utilizes both AC input and battery power to supply continuous load.
5. Power Support Mode – Supplements AC input with additional battery power when energy demand is high.

These advanced features ensure efficient energy usage, extended battery life, and continuous power availability.

Reliable and Efficient Battery Charging Technology

The SC-3000’s 3-stage battery charging system ensures that your batteries are charged efficiently while preventing overcharging. It follows a smart charging cycle:

• Bulk Charging – Rapidly charges depleted batteries to restore power.
• Absorption Charging – Gradually reduces current as the battery approaches full capacity.
• Float Charging – Maintains charge levels without overcharging, extending battery lifespan.

This intelligent charging system supports multiple battery types, including:

• Lead-Acid (AGM, Gel, Flooded)
• Lithium-Ion (LiFePO4, NMC, etc.)

Additionally, the optional battery temperature sensor allows for temperature-compensated charging, which improves performance and prevents overcharging in extreme conditions.

Rugged, Durable, and Built for Harsh Environments

The SC-3000 inverter charger is engineered for durability, making it an ideal solution for mobile and stationary power applications. It operates efficiently in ambient temperatures ranging from -20°C to 40°C without power derating, ensuring consistent performance even in demanding conditions.

Additionally, the SC-3000 features multiple layers of protection, including:

• Overload Protection – Prevents damage due to excessive power loads.
• Reverse Polarity Protection – Shields against incorrect battery wiring.
• Over-Temperature Shutdown – Prevents overheating under high loads.
• Short-Circuit Protection – Ensures safety in case of wiring faults.

With industry certifications such as UL458, FCC Class A, CE EN62368-1, and e-Mark, this unit is designed to meet global safety and reliability standards.
