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
- 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 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.

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
- 1Mount 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.
- 2Connect battery first
Strip your battery cables, insert into the labeled screw terminals, and tighten firmly. The controller must read battery voltage before anything else.
- 3Connect 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.
- 4Connect 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.
- 5Verify 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?
| 20A | 30A | 40A | 50A | 60A | |
|---|---|---|---|---|---|
| Max Panel Power (12V) (W) | 240W | 360W | 480W | 600W | 720W |
| Max Panel Power (24V) (W) | 480W | 720W | 960W | 1200W | 1440W |
| Typical Battery Bank | 100-200Ah | 150-300Ah | 200-400Ah | 250-500Ah | 300-600Ah |
Always add 25% headroom above your panel's measured maximum current. Over-paneling can trip protection on peak days.

Questions and answers
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.
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.
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.
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.
The terminals accept 12 to 14 AWG stranded or solid copper wire securely. Use a ferrule for fine-stranded wire for the best connection.
Yes, it's compatible with sealed lead-acid, flooded, AGM and gel batteries. The PWM charging profile keeps all types safe from overcharge.
