EXPLANATION REASON SOLUTIONS
DC Bus High BUS voltage is
over-high
/ Try to restart the inverter. Check
if the fault still occurs. If not, it
means it is caused by an occasional
situation,or contact after-sales.
Back-Up Over
Load
Back-up side is
over loaded
Total back-up load
power is higher
than the back-up
nominal output
power
Decrease back-up loads to make
sure the total load power is lower
than back-up nominal output power
(please refer to page 24).

3.2 Troubleshooting
Checking As Start A-ES Up And Turn On AC Power
Battery settings, BMS communication and safety country:
After connecting Solar-WiFi* (*The Wi-Fi signal is named
the last 8 characters of the inverter's serial No.), check on PV
Master App "Param" to make sure battery type is the same as
what you have installed, and "Safety Country " Setting is right.
Please set it right in "Set" if the setting is not right.
Note: For compatible lithium batteries, BMS status will display
"Normal" after selecting the right battery company.
Functional Safety: The software version is displayed on PV
Master App "Param"→"Firmware Version".

Problems During Operation
A-ES does not start up with battery only
Solution:
Make sure the voltage of battery is higher than 100V, otherwise battery cannot start A-ES up.
A-ES not started up with PV only
Solution:
1. Make sure the voltage of PV is highter than 100V (need 200V to enter on-grid mode).
2. Make sure the connection between A-ES and PV panels: polarities are (+/-) not reversed.
