96V-614V High-Voltage PWM Photovoltaic Charge Controller

Core Technological Innovations

Intelligent Algorithms and Precision Control: Equipped with advanced PID algorithms and dual-loop (voltage loop + current loop) control, supporting current-limited charging mode with dynamically adjustable charging strategies to boost power generation by 5%-30%. Three-stage charging (constant current, constant voltage, float charge) maximises utilisation of photovoltaic modules and battery energy.
Fully Modular and High Reliability:
Fully IGBT modular design ensures electrical isolation and optimised thermal management. Combined with a fully enclosed air duct structure and intelligent fan cooling, it adapts to extreme environments from -40°C to 70°C. Patented secondary protection prevents battery damage caused by power switch failures.
Safety Protection and Long-Life Design:
Integrated multiple protection mechanisms including overvoltage, undervoltage, overtemperature, and short-circuit protection. Multi-stage charging strategy extends battery lifespan. Supports automatic temperature compensation and RTC real-time clock to guarantee precise and reliable system operation.
User-Friendly Interaction and Intelligent Monitoring
Features a colour LCD touchscreen with multilingual support (including Chinese and English), displaying real-time power generation, power curves, and ambient temperature. Supports standard Modbus protocol via RS485 interface for remote system monitoring, with optional dry contact control for charging/discharging.

Application Scenarios and Market Value
This controller is suitable for large-scale ground-mounted power stations, commercial and industrial energy storage, and microgrids in remote areas. Its ultra-wide voltage input accommodates multiple photovoltaic module types, while efficient energy management reduces the cost per kilowatt-hour. The product holds EMC certification and offers excellent interference resistance, ensuring stable operation in complex electromagnetic environments.
