Professional MPPT Solar Charge Controller - 30A/40A/50A/60A Smart PV Regulator for Off-Grid Systems
Product Overview
1. Advanced MPPT Technology with 99% Tracking Efficiency
- Intelligent Maximum Power Point Tracking (MPPT) extracts 30% more solar energy than PWM controllers
Auto-adjusts to weather conditions (cloudy/sunny) for optimal charging performance
2. Wide Compatibility for Multiple Battery Types & Voltage Systems
- Works with 12V/24V/36V/48V lead-acid (sealed/GEL/flooded) & lithium batteries (LiFePO4 optional)
High PV input voltage (100V DC Max) supports series-connected solar panels
3. Smart Battery Management to Extend Battery Life by 200%
- 4-stage charging (bulk/absorption/float/equalization) prevents overcharge/discharge
-20°C~60°C temperature compensation ensures safe operation in extreme environments
4. Military-Grade Protection System
- Triple reverse polarity protection (PV/battery/load)
4000V lightning surge protection for outdoor installations
Over-current/short-circuit/overheat protection with auto-recovery
5. User-Friendly Operation
- 3.2-inch LCD display shows real-time data: PV voltage/charging current/battery temp
Dual USB outputs (5V/3A) for fast-charging phones/tablets
Optional Bluetooth/WiFi module for remote monitoring via app
