Durable MPPT Solar Charge Controller 30A 40A 50A 60A for Off-Grid Solar Energy System
Our MPPT solar charge controller is the ideal choice for anyone seeking high efficiency, long lifespan, and robust protection in their solar power system. Whether for residential, commercial, or industrial use, it ensures maximum energy harvest and battery performance.
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
