Waterproof MPPT Solar Panel Charger Regulator 30A-60A for Off-Grid 12V/24V/36V/48V Battery Systems
Universal Compatibility for Future-Proof System Design
Engineered for complete system flexibility, our controller automatically detects and adapts to 12V/24V/36V/48V configurations without manual intervention. It supports the full spectrum of energy storage solutions, including all lead-acid variants (GEL, AGM, flooded) and modern lithium (LiFePO4) batteries with customizable charging profiles. The high 100V DC PV input capacity enables innovative panel configurations, allowing longer series strings that reduce wiring complexity and voltage drop. This future-ready design accommodates both current installations and planned system expansions, making it the most versatile solution on the market.
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
