1. Connect the Battery: First, connect the battery terminals to the controller. This allows the unit to auto-detect the system voltage (12/24/36/48V).
2. Connect the Load: Connect any DC loads to the load terminals (optional).
3. Connect the Solar Panel: Finally, connect the PV array to the solar terminals.
4. Note: Disconnect in reverse order (Solar first, then Battery). Always install a fuse within 150mm of the battery terminal.

Is this a genuine original part?

Yes, this is an authentic EPEVER ViewStar AU series controller, supplied by Solarika, ensuring high performance and safety compliance.

How do I know if it is compatible?

If your system requires a 30A charge current and operates on 12V, 24V, 36V, or 48V, this controller is compatible. Please ensure your PV open circuit voltage (Voc) does not exceed 96V.

What protections are built into this unit?

The VS3048AU includes comprehensive protection against PV reverse polarity, battery overcharge, battery over-discharge, battery reverse polarity, load overload, and load short circuiting.
