10A PWM Solar Charge Controller with Auto Parameter LCD Display

- 【Smart 3-Stage PWM Charging】: This 10A PWM solar battery controller delivers safe, efficient trickle charging for 12V/24V lead-acid and lithium batteries.Adopts bulk, absorption, and float 3-stage charging mode to effectively prevent overcharging and extend battery service life.Supports up to 120W (12V) / 240W (24V) solar panels, perfect for tiny solar setups. Note: Lithium batteries require manual mode selection, Default setting is for lead-acid batteries. - 【Wide Tiny Scenario Adaptation】: Perfect for small off-grid power projects and battery maintenance.Ideal for small trailers, boat battery maintenance, gate openers, chicken coop lights, and garden lights.A beginner-friendly solar charge controller for mini DIY projects. - 【Built-In Power-Off Memory】: Never reprogram after a power outage. The built-in industrial microcontroller saves all your parameters (voltage thresholds, timer settings, etc.). When power is restored, this solar charge controller is ready ? no reset required, no lost configurations. - 【Easy-Read LCD & Timer Control】: Check battery status and set automatic on/off schedules without any fuss. The backlit LCD screen shows real-time voltage, charging current, and mode. Use the adjustable timer to automate small pumps, exhaust fans, bird feeders, or bird bath heaters. No manual switching needed. - 【Full Protection, Auto Recovery】: Built to forgive first-time DIY mistakes. This solar battery controller guards against overcurrent, short circuits, reverse polarity, open circuits, overvoltage, overheating, and anti-backflow. All protections are self-recovering ? when faults clear, it resumes normal operation. No fuses to replace. - 【Dual USB for Convenient Charging】: Keep your phone topped off directly from the controller. Two 5V/2A USB ports eliminate extra adapters, perfect for tight spaces like truck cabs, hunting blinds, or small boat consoles. - 【Wide Battery Compatibility & Simple Installation】: Auto-detects 12V or 24V systems. Works with OPEN, AGM, GEL lead-acid batteries and lithium (Li-ion, LiFePO4). For lithium batteries, manually select B2 (Li-ion) or B3 (LiFePO4) via the button before connecting solar panels. Follow wiring: battery FIRST, then solar panel, then load (reverse to disassemble). IMPORTANT: Always connect battery FIRST during installation to avoid controller damage. A budget-friendly 10A solar charge controller for tiny off-grid needs.
