Configure all secondary battery cabinets before making further connections. | ||
Configure the primary battery cabinet before making further connections. | ( > Configuring the primary battery cabinet with multiple battery cabinets) | |
Connect the AC cables to the inverter. | ||
Connect the network cables to the inverter. | ||
Connect the battery communication cables for CAN to the inverter. | ||
Connect the DC lines to the inverter. Record the device type and serial number of the inverter in the commissioning report. | ||
