When pairing the AES battery cabinet with a Solis inverter, discharge performance is governed by the inverter's battery input rating, which ranges by model from 32.1 kW to 55 kW. The AES CAB-106 / CAB-160 / CAB-210 supports continuous output of 52 / 78 / 104 kW (C/2 rate) or approximately 157 Adc.

Inverter Model	Max Power Battery
S6-EH3P29.9K03-H-AU	32.1 kW
S6-EH3P30K03-H-AU	33 kW
S6-EH3P40K03-H-AU	44 kW
S6-EH3P50K03-H-AU	55 kW

Properly Rated Cables. Cables for high-voltage DC connections should be rated at least 1 kV to provide a safety margin for the system’s maximum battery voltage of 375 Vdc (CAB-106), 575 Vdc (CAB-160), or 750 Vdc (CAB-210). This enables compliance with AS/NZS 5000 or AS/NZS 3008 for derating calculations.

Inverter Ports	Max. Terminal Rating	Terminal Wire Size Range
Battery Port 1	70 Adc	25 mm² (4 AWG)
Battery Port 2	70 Adc	25 mm² (4 AWG)

NOTICE

EQUIPMENT DAMAGE

Confirm the polarity of all DC connections before powering on the system. Incorrect polarity can damage the equipment and void the warranty.
The AES battery cabinet supports a maximum charge/discharge current of 157 A, or about 78 A per port. Use appropriately sized fuses to maximize charging and discharging energy without compromise.

Failure to follow these instructions may result in equipment damage.
