Description
【20A PWM Controller — Precision 12V Charging】As the "brain" of your 12V solar system, this controller is purpose-built for 12V batteries (not compatible with 24V/36V systems) and works seamlessly with solar panels up to 300W. Equipped with upgraded 20A PWM technology, it delivers twice the output current of standard 10A controllers — enabling faster, more stable charging. Smart charging algorithms regulate current flow, reducing energy loss and improving overall system efficiency. Please note: a polarity converter is not included. Be sure to connect positive and negative terminals correctly — proper wiring ensures safe, reliable operation.
【Intuitive Monitoring + Plug-and-Play — User-Friendly by Design】The high-definition LCD screen and clear LED indicators give you instant visibility into battery level, charging mode, current, voltage, and key system statuses — no guesswork required. Compatible with lead-acid, lithium, and other battery types, with customizable charging modes for each type. A single button press displays real-time current for 5 seconds, then the screen automatically returns to battery voltage to conserve power. Equipped with SAE connectors (SAE adapter cable sold separately) and plug-and-play MC4 connectors — simply connect your own cables to start using immediately.
【Zero Idle Drain + Reverse Current Protection — 24/7 Battery Guardian】Upgraded circuit design delivers near-zero standby power consumption, preventing unnecessary battery drain. Built-in anti-reverse diodes effectively block reverse current — so even after sunset, your battery won't be drained. This dual protection extends battery lifespan and lowers replacement costs, delivering reliable, long-term performance for off-grid systems.
【Type-C & USB-A — Power On the Go】Equipped with a TYPE-C and a USB-A port, this controller powers smartphones, tablets, cameras, power banks, and other devices — directly from solar energy or stored battery power. Compatible with a wide range of TYPE-C/USB devices. Perfect for outdoor camping, RV trips, off-grid living, and emergency backup — portable power, ready when you need it.
【6-in-1 Protection — Beyond Standards】Built with six key safeguards: overcharge, overvoltage, reverse current, reverse polarity, short-circuit, and over-temperature protection. These layers prevent equipment damage, fire hazards, and battery failures — keeping your solar system and batteries secure in any environment.
【Quality You Can Rely On — Backed by Expert Support】This 12V PWM controller and other models in our lineup are built for consistent, reliable performance. Our team is knowledgeable about a wide range of solar controller issues — whether you need help with installation, compatibility, or troubleshooting, we're here to assist.
