Common Q&A:

Q: How do I install it? A: The installation process involves the following steps: 1. Connect the battery. 2. Connect the solar panels. 3. Connect the DC load.

Q: Why is the LCD screen blank? A: When the battery voltage is too low (≤ 8V), the controller will shut off to protect the system. This results in the LCD screen becoming blank. After the solar panels have recharged the battery, and it reaches 12.6V, the controller will re-start and the LCD will display again.

Q: What battery types are compatible with this controller? A: The controller supports three types of lead-acid batteries: B01 (Open), B02 (AGM), and B03 (GEL). It is not compatible with nickel-hydride, lithium-ion, or other battery types. Keep children away from the battery and controller.

Additional Notes: 1. Wire Range: 26-12 AWG 2. Ensure the battery voltage is at least 11V for initial use to allow the controller to properly detect the battery type. 3. Old batteries may degrade in capacity after many charge cycles, potentially dropping below 8V, causing the controller to shut off (LCD becomes "dead"). 4. This controller is for indoor use only, with an operating temperature range of -35°C to +60°C. During hot, sunny days, the outdoor temperature may exceed 60-75°C, so keep the controller in a cool, well-ventilated location for optimal heat dissipation.
