Installation Guide

Battery Parallel Connection

If using multiple batteries, connect them in parallel using the supplied M8 red-and-black battery cables while the battery power switch and circuit breakers are OFF. Set the six-position DIP switch on each battery unit according to the ID table provided in the manual (e.g., ID 1 is Master, ID 2 is Pack 2) and connect the inter-battery communication cables.

AIO & Battery Connection

1. Prepare the M6-to-M8 battery cables with copper lugs.
2. Verify all switches on the AIO and battery are OFF.
3. Remove the terminal cover on the AIO.
4. Insert the M6 copper lugs into the BAT- terminals of the AIO and tighten firmly.
5. Connect the M8 copper lugs to the corresponding positive and negative terminals on the server rack battery (red to positive, black to negative).

AIO & Solar Panel Connection

1. Prepare the single-ended MC4 cables.
2. Connect the bare-wire ends to the AIO's PV terminals (red to PV+, black to PV-).
3. Mate the MC4 connectors: insert the male MC4 plug into the female MC4 plug of the PV array, and the female MC4 plug into the male MC4 plug of the PV array.

Troubleshooting

If the AIO screen displays fault codes, refer to the following:

• Battery Unable to start: Switch on battery and press RESET for 6s, or charge with 54-57.6V.
• Communication fail: Check communication cable type, DIP switch settings, and AIO protocol settings.
• AIO Error [06] (Battery Over-Voltage): Discharge battery until voltage falls below the recovery point.
• AIO Error [13][14] (Bypass Overload): Reduce connected load and restart the AIO.
• AIO Error [17] (Short-Circuit): Examine load connections and power-cycle the unit.
