Description

Regulate your solar panel output with absolute clarity. This auto-detecting 12V/24V charge controller puts a live LCD readout in front of you, runs dual USB outputs, and protects your battery bank…

Intelligent 12/24V auto-detection solar charge controller with dual USB charging and multiple amperage options

Solves
  • Unregulated solar panel power damaging batteries
  • Lack of real-time monitoring of charge status
  • Need for multiple charging solutions in off-grid systems
  • Manual voltage/amperage configuration errors

Stop frying your batteries and watch every volt

Your panels feed raw, unregulated power straight into expensive batteries. This controller meters it perfectly — and shows you exactly what's happening on a glance-able LCD.

See Your Charge, Protect Your Bank

A Live LCD That Ends The Guessing

The recessed LCD shows real-time charge status, voltage and current, so you always know what your system is doing. No more decoding cryptic beeps or reaching for a multimeter.

Auto-Detects 12V or 24V Instantly

Automatic voltage detection eliminates the manual setup errors that fry batteries. Wire it, power it, and the controller figures out your system voltage before the first charge pulse.

Dual USB ports on solar charge controller, ready to charge a phone or USB device

Dual USB Keeps Devices Charged

Two 5VDC USB ports let you charge phones, headlamps or GPS units straight off the controller — no extra adapter needed. Perfect for when every outlet counts.

Six heavy-duty screw terminals on the controller's bottom edge, ready for solid wire connections

Heavy Screw Terminals Built To Hold

Six recessed screw terminals make secure, vibration-resistant connections for panel, battery and load. They grip tightly even when the road gets rough — no intermittent charging.

Installation In Minutes

  1. 1
    Mount the controller

    Choose a dry, well-ventilated spot inside your electrical bay or power closet. Use the included bracket and screws to fix it flat against the wall.

  2. 2
    Connect battery first

    Strip your battery cables, insert into the labeled screw terminals, and tighten firmly. The controller must read battery voltage before anything else.

  3. 3
    Connect solar panel

    With the battery already connected, wire your solar panel to the panel terminals. The auto-detection kicks in and the LCD lights up with system status.

  4. 4
    Connect DC load (optional)

    If you have a direct DC load, wire it to the load terminals. The controller can manage low-voltage disconnect if needed.

  5. 5
    Verify operation

    Once powered, check the LCD: it should display the correct voltage, battery level, and charging indicators. Your bank is now protected.

From Blind To Real-Time Monitoring

The Black Box Problem

You built your off-grid system carefully — panels, batteries, inverters. But the charge stage is a black box. No display, no feedback. You hope the batteries are charging correctly, but the first sign of trouble is a dead bank and a ruined trip.

What Overcharging Costs

Unregulated voltage spikes and chronic overcharge silently eat away at deep-cycle battery capacity. You won't see it until one morning the fridge is dead or the water pump won't start. The damage is permanent — and avoidable.

A Controller You Can Read

This controller brings the dark stage into the light. Auto-detection instantly matches 12V or 24V. The recessed LCD shows charging voltage, current, and system status. PWM regulation gently tops off your bank instead of punishing it. And while you're checking the readout, dual USB ports keep your phone charged.

Which Amperage Do You Need?

Always add 25% headroom above your panel's measured maximum current. Over-paneling can trip protection on peak days.

Questions and answers

Does it auto-detect 12V and 24V systems, or do I configure it manually?
w
Wanelo · seller

It auto-detects your system voltage on power-up. No dip switches, no meter — just wire the battery first, and the controller reads the voltage and sets itself.

Is this PWM or MPPT, and which do I need for my panels?
w
Wanelo · seller

This is a PWM controller. It's ideal when your panel array voltage closely matches your battery bank voltage (common in 12V and 24V off-grid setups). MPPT is only needed when you have a large voltage mismatch — for most small to mid-sized systems, PWM is more than enough and far more cost-effective.

How do I choose between the 20A, 30A, 40A, 50A and 60A versions?
w
Wanelo · seller

Match the controller's amp rating to your panel array's maximum current. A 100W panel typically outputs about 5.5A at 18V, so a 20A controller handles a 200W 12V system. For a 400W array, size up to 40A. Choose a tier with at least 25% headroom to stay safe on hot, high-irradiance days.

Can the dual USB ports charge a phone while the battery is charging?
w
Wanelo · seller

Yes, the USB output runs independently of the battery charge circuit. You can top off devices at any time as long as the controller is powered.

What gauge wire do the screw terminals accept?
w
Wanelo · seller

The terminals accept 12 to 14 AWG stranded or solid copper wire securely. Use a ferrule for fine-stranded wire for the best connection.

Will it work with lead-acid, AGM and gel batteries?
w
Wanelo · seller

Yes, it's compatible with sealed lead-acid, flooded, AGM and gel batteries. The PWM charging profile keeps all types safe from overcharge.
