10. User Tips
- Solar Panel Configuration: When connecting multiple solar panels, ensure their series and parallel configurations respect the controller's maximum PV input voltage (150VDC) and current (60A). For example, if using 610W panels, connecting two in series and then multiple such strings in parallel is a common approach, but always verify the total voltage and current remain within the controller's limits.
- Voltage Auto-Recognition: The controller automatically detects 12V, 24V, 36V, or 48V battery systems. Ensure your battery bank matches one of these standard voltages for proper operation.
- Battery Type Selection: Accurately setting the battery type (Gel, Sealed, Flooded, Lithium) in the controller's settings is crucial for optimal charging and battery longevity. For lithium batteries, remember to also set the correct capacity.
