Renogy 12V 30A PWM Solar Charge Controller – Wanderer Li with Temp Sensor, 4-Stage Charging for Lithium/Gel/Flooded Batteries, Overload/Short Circuit/Reverse Polarity Protection

Features

• 12V Solar Controller for Lithium/AGM/Gel/Flooded Batteries：Compatible with 12V lithium, AGM, gel, and flooded lead-acid batteries, this PWM controller auto-adjusts charging curves for RVs, boats, and off-grid systems. LED indicators let you switch battery types and monitor real-time charging stages (Bulk/Boost/Float/Equalization) to extend battery lifespan
• 4-Stage PWM Charging with Full Protection：Maximize performance with 30A Bulk Charge (80% fast charging), Boost Charge (120-minute voltage stabilization), Float Charge (micro-current maintenance), and auto Equalization (every 25 days). Built-in safeguards prevent reverse polarity, overcharging, overload, and short circuits—ideal for harsh climates
• Ultra-Compact & Waterproof Design：Fits tight spaces (5.5”x3.9”x1.8”) in RV panels or marine compartments. IP32-rated waterproof casing and corrosion-resistant materials ensure durability. Tool-free DIN rail or wall mounting for quick outdoor installation
• Multi-Battery Support & Temp Sensor Ready：Preconfigured for lithium (LiFePO4), AGM, gel, and flooded batteries. Add the BT-1 Bluetooth module for temperature compensation (-4°F to 140°F), preventing winter undercharge and summer overvoltage damage
• Real-Time Monitoring via Bluetooth : Pair with the BT-1 module (sold separately) to track solar input, battery SOC, and fault alerts (overload/reverse current) on the DC Home App—perfect for remote off-grid systems
