Key Product Advantages

1. Low-Resistance Transmission, Stable Performance

Utilizing a precision-milled zinc alloy conductive body, the terminal effectively reduces transmission resistance. It supports stable, long-term operation under heavy loads, preventing power loss and overheating caused by poor contact, thereby significantly enhancing the transmission efficiency of energy storage and inverter systems.

2. Centralized Multi-Port Wiring, Efficient Installation

The multi-port structure allows for the simultaneous connection of multiple large-gauge cables (0/4GA), enabling centralized line management. This eliminates the clutter associated with traditional distributed wiring, standardizes the layout, and drastically reduces the time required for equipment installation and wiring.

3. Robust Durability and High Safety

Featuring a high-strength PC insulating housing paired with a solid metal body, the unit offers excellent compressive strength, corrosion resistance, and insulation properties. It is designed to withstand challenging conditions—such as vehicle vibrations and the humid environments found on boats—effectively eliminating risks of short circuits or electrical leakage and ensuring the long-term safe operation of DC systems.

4. Flexible Customization and Diverse Services

Leveraging a standardized manufacturing system, Yiqi offers one-stop services including structural adjustments, parameter customization, private labeling, and OEM mass production. We support everything from small-batch trial orders to large-scale production runs, meeting the diverse procurement needs of our customers.

Real-World Application Cases

1. RV Off-Grid PV Energy Storage System Project

A European RV conversion company utilized Yiqi’s High Current Energy Storage Inverter Power Terminal for a 4.8kW off-grid PV energy storage project. Paired with a 10kWh battery pack and an inverter, the terminal provides power to the RV’s electrical appliances. The client’s previous terminals suffered from issues such as overheating during prolonged power delivery and loose wiring caused by vehicle vibrations.

After switching to Yiqi products, the multi-port centralized wiring structure streamlined the connections between the PV panels, battery pack, and inverter. Following a 72-hour continuous full-load test and extensive road testing, the terminals showed no significant heat buildup, maintained stable contact resistance, and exhibited no loose wiring. The overall stability of the energy storage system improved by 30%, completely resolving connection faults and earning high praise from the client.

2. Yacht Backup Power Inverter System Application

A domestic marine equipment manufacturer utilized Yiqi’s high-current terminals in a 12V marine backup power inverter system. Marine environments—characterized by high humidity and corrosive salt air—demand exceptional corrosion resistance and stability from components. Yiqi’s terminals, featuring a zinc-alloy anti-corrosion finish and PC insulation structure, are perfectly suited for these harsh conditions.

On-board testing confirmed that the product reliably handles high-current switching between the yacht’s backup battery and inverter, ensuring continuous power for navigation and onboard appliances. It resolved issues common to traditional marine terminals—such as premature aging and failure—thereby effectively extending the maintenance intervals for the vessel's electrical system.
