Q: What does the LCD screen show?

A: It displays battery voltage, charging current, charging status (day/night/float), load status, and accumulated amp-hours. Cycle through modes with the button.

Q: Can I use the USB ports while charging the battery?

A: Yes, both the battery charging and USB outputs operate simultaneously as long as solar input is available.

Q: What size solar panel can I use with the 30A model?

A: Up to 360W (12V) or 720W (24V). You can connect multiple panels in parallel up to the maximum current rating.

Q: Does it have a timer function for load control?

A: Yes, the LCD models support programmable timer settings for automatic load ON/OFF scheduling, useful for street lighting and timed applications.
