Frequently Asked Questions
Q: What battery types are compatible with this PWM solar charge controller?
A: This solar charge controller is compatible with a wide range of battery chemistries including Sealed lead-acid, Gel, Flooded (wet) lead-acid, as well as Lithium Iron Phosphate (LiFePO4) and Lithium (LiCoMnNiO2). The controller automatically detects your battery voltage (12V or 24V) and adjusts charging parameters accordingly.
Q: What is the difference between the 10A, 20A, and 30A models?
A: The amperage rating determines the maximum current the controller can handle and, consequently, the maximum solar panel wattage you can connect. The 10A model supports up to 120W (12V) or 240W (24V), the 20A up to 240W (12V) or 480W (24V), and the 30A up to 360W (12V) or 720W (24V). Choose based on the total wattage of your solar panel array.
Q: Does this controller work with off-grid home lighting systems?
A: Yes! This PWM solar charge controller is designed for home photovoltaic and off-grid lighting systems. Its multiple load control modes — including 24-Hour, Light Control, and Light + Dual Timer — make it ideal for automating solar-powered lighting installations.
Q: Can I charge USB devices directly from this solar controller?
A: Absolutely. The controller features dual USB output ports (5V / 2A each), allowing you to charge smartphones, tablets, or other USB-powered devices directly from your solar battery system without an additional inverter or adapter.
