Description
BIPV320K6 – 320kW MPPT Controller
Category: DC/DC MPPT Controller
Application: Solar-Storage Systems · Microgrids
Manufacturer: Imax Power Technology Co., Ltd.
🔋 What this product does: The BIPV320K6 MPPT Controller maximizes PV energy harvest and efficiently charges battery banks in DC-coupled systems, reducing energy conversion losses and improving system reliability for commercial and industrial storage projects.
⚙️ Technical Architecture
The BIPV320K6 integrates six independent MPPT channels, each capable of tracking the maximum power point of individual PV sub‑arrays with different orientations. The DC output is directly connected to the battery bus (1330 V DC nominal), eliminating the need for separate PV inverters and AC distribution. This DC‑coupled architecture minimizes conversion steps, increasing overall system efficiency by 5–8% compared to AC‑coupled designs.
🎯 Application Positioning
- Commercial & industrial PV + storage
- Island and coastal high‑salt environments
- Off‑grid renewable systems
- EV charging stations with solar integration
- Microgrid backup and peak shaving
Product Advantages
Safety & Reliability
Built‑in short‑circuit, reverse polarity, over‑temperature, and surge protection. IP66 + C5 corrosion resistance for harsh outdoor conditions.
High Efficiency
Maximum efficiency of 99.4% minimizes energy loss during DC/DC conversion, maximizing PV yield and reducing system operating costs.
Intelligent Control
RS485 communication enables seamless integration with EMS and BMS. Real‑time monitoring, anti‑reverse current, and fast response to load changes.
Flexible Integration
Wall‑mounted compact design, supports multiple installation methods. Six MPPT channels adapt to various PV array orientations without extra optimizers.
