To make sure the battery communicates to inverter unit successfully, users have to use PV
Master to choose the right battery option on PV Master:
APP Installation And Connection:
Connect phone & Inverter
Wi-Fi SSID: Solar-WiFi***
Password: 12345678
Download
and install
PV Master
Note: If Battery Under Voltage happens during working status, by pressing battery switch for 5
times in 10 seconds, BMS will compulsively close MOS, so that inverter will detect battery open
circuit voltage to charge battery.
Select “SECU-A5.4L” on battery page in PV
Master Application
Notes:
1. Select wrong battery will lead to BMS
communication failure
2. Select wrong number of batteries the
input and output current will be limited
and the parameter indicated by the
converter is inconsistent with the actual
value of the battery.
3. For the complete commissioning of the
whole ESA system, please go to ESA
instruction.
