Installation Tips
- Ensure the battery has sufficient voltage before first connection so the controller correctly auto-detects 12V or 24V.
- Mount the controller as close to the battery as possible to minimize voltage drop from wiring.
- Install on a flat, well-ventilated surface — the unit generates some heat during normal operation.
- For lead-acid batteries only (open/sealed/gel). Do not use with lithium, NiMH, or other battery chemistries.
- Use PV solar panels as the sole charging source — do not connect DC power supplies or other sources.

Frequently Asked Questions
Q: What battery types are compatible with this solar charge controller?
A: This PWM solar charge controller is designed exclusively for lead-acid batteries, including open (flooded), sealed (AGM), and gel/colloidal types. It is not compatible with lithium-ion, lithium iron phosphate (LiFePO4), nickel-metal hydride (NiMH), or any other battery chemistry.
Q: Does this controller automatically detect whether my system is 12V or 24V?
A: Yes — the controller features automatic 12V/24V voltage detection. When you first connect it, ensure your battery has adequate charge so the controller can correctly identify your system voltage. No manual switching is required.
Q: Can I adjust the charging and discharging voltage thresholds?
A: Absolutely. All key parameters — including full charge cut-off voltage, discharge cut-off voltage, discharge recovery voltage, and more — are fully adjustable via the LCD menu. Hold the Menu button for 5 seconds to enter parameter-setting mode and use the Up/Down buttons to customize your settings.
Q: What does the Dual USB output on this solar charge controller do?
A: The two built-in USB ports provide a regulated 5V output (up to 2.5A combined) so you can charge smartphones, tablets, GPS devices, and other USB-powered accessories directly from your solar battery bank — no separate inverter or USB adapter needed.
