Caution:
 Before connection, the positive and negative pole of the inverter input interface and the battery
output interface should be confirmed.
 The red power line is connected to the positive pole and the black power line is connected to the
negative pole.
 Before connection, it is necessary to confirm the charge and discharge parameters of the
inverter interface.
 Voltage and current should meet the requirements of Table 2-2 battery performance
parameters.
 When you use battery in parallel, it doesn’t need to change the DIP switch of the master module
in the master Powerbox which communicates with the inverter directly.
 Note: For more information of matching inverter brands, please subject to the latest document
<The list of compatibility between Dyness ESS and Inverters >.
 The following operations can only be performed after being authorized by DYNESS:
 How to judge that the communication between the product is normal:
 If there is communication between the inverter and battery system, it can be judged by the
maximum charge and discharge current value on the inverter sent by the battery.
1. If there is communication between the inverter and battery system, it can be judged by
the maximum charge and discharge current value on the inverter sent by the battery.

number of modules
If the equation holds after calculation, it means communication between the powerbox
Pro is normal.
2. If the Powerbox Pro light board shows three different colors flash alternately, it means
the communication between Powerbox Pro is fault.
