4.2 Wiring Sequence

Follow this sequence for safe and proper connection:

1. Connect the Battery: First, connect the battery to the controller's battery terminals (BATT+/-). Ensure correct polarity. The controller will power on.
2. Connect the Solar Panel: Next, connect the solar panel array to the controller's PV terminals (PV+/-). Ensure correct polarity.
3. Connect the Load: Finally, connect the DC load to the controller's load terminals (LOAD+/-).
4. Optional Connections: If using, connect the Remote Temperature Sensor (RTS) to the RTS port and any communication cables (e.g., RS485) to the COM port.

Important Safety Note: Always disconnect the solar panel first, then the battery, when performing maintenance or disconnecting the system. Reconnect in reverse order: battery first, then solar panel.

5. Operating Instructions

The EPEVER XTRA1210N controller features an intuitive display and buttons for easy operation and monitoring. The display provides real-time system status, including battery voltage, charging current, load status, and more.
