Note: Lithium batteries require manual mode selection, Default setting is for lead-acid batteries.\u003c\/li\u003e\n\u003cli\u003eWide Off-Grid Scenario Adaptation: Perfect for weekend trips and medium off-grid systems.Works great on small RVs, campervans, off-grid tiny houses, cargo trailer conversions, overland vehicles, and boat battery banks.A reliable solar charge controller for various off-grid power needs.\u003c\/li\u003e\n\u003cli\u003eBuilt-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.\u003c\/li\u003e\n\u003cli\u003eEasy-Read LCD \u0026amp; Timer Control: Check battery status and set automatic on\/off schedules without any fuss. The backlit LCD shows real-time voltage, charging current, and mode. Use the adjustable timer to automate RV lights, cabin fans, overland vehicle fridges, or water pumps. No manual switching — set it and forget it.\u003c\/li\u003e\n\u003cli\u003eFull Protection, Auto Recovery: Built to forgive first-time DIY mistakes. This solar panel regulator 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 change, no damaged components.\u003c\/li\u003e\n\u003cli\u003eDual USB for Convenient Charging: Keep your phone or tablet topped off directly from the controller. Two 5V\/2A USB ports eliminate extra adapters, perfect for tight spaces like RV cabinets, camper van consoles, or small boat dashboards.\u003c\/li\u003e\n\u003cli\u003eWide Battery Compatibility \u0026amp; Simple Installation: Auto-detects 12V or 24V systems and works with OPEN, AGM, GEL lead-acid and lithium batteries (Li-ion, LiFePO4). For lithium batteries, manually select B2 (Li-ion) or B3 (LiFePO4) via the button before connecting solar panels. Wiring sequence: battery FIRST, then solar panel, then load (reverse to disassemble). IMPORTANT:Always connect battery FIRST during installation to avoid controller damage. A cost-effective 30A solar charge controller for real-life off-grid systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43251080200401,"sku":"BW-B0H45FJXH5","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/61ZZS7zPS0L._AC_SL1500.jpg?v=1786993928","url":"https:\/\/belmontwarehouse.com\/products\/30a-12v-24v-pwm-solar-charge-controller-lcd-display-dual-usb-timer-function-lead-acid-lithium-batteries-solar","provider":"Belmont Warehouse","version":"1.0","type":"link"}
