Relay Check
Failure
Self checking of
relay failure
Neutral & ground
cables are not
connected well on
AC side or just an
occasional failure
Check (use multi-meter) if there is
high voltage (normally should be
lower than 10V) between N & PE
cable on the AC side. If the voltage
is higher than 10V, it means the
Neutral & ground cable are not
connected well on AC side or restart
inverter.
DC Injection
High
/
The inverter
detects a higher
DC component in
AC output
Try to restart the inverter,check
if it still occurs.If not,it is just an
occasional situation.Otherwise,
contact after-sales immediately.
EEPROM R/W
Failure
/
Caused by a
strong external
magnetic eld etc.
Try to restart the inverter,check
if it still occurs.If not,it is just an
occasional situation.Otherwise,
contact after-sales immediately.
SPI Failure
Internal
communication
failure
Caused by a
strong external
magnetic eld etc.
Try to restart the inverter,check
if it still occurs.If not,it is just an
occasional situation.Otherwise,
contact after-sales immediately.
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 2.4.2 On-Grid &
Back-Up Connection).
NOTE: All the errors about battery happen only on Lithium battery with BMS communication.
4.2 Troubleshooting
Checking Before Starting S-BP Up
Battery connection:
Conrm the conncetion between S-BP and battery : polarity (+/-) are not reversed, refer to 4.2-1.
On-Grid & Back-Up conntecion:
Conrm On-Grid connected to power gird and Back-Up to loads: polarity (L/N) are not reversed,
refer to 4.2.2.
Smart Meter & CT Connection:
1. If connection between Smart Meter and CT (port 1 and 4 on Smart Meter) is OK.
Note: After turn on AC power, the COM led on Smart Meter should be blinking.
2. Make sure CT is connected between house loads and grid. And it follows the House Grid
direction on CT, refer to 4.2.3.
Note: For three-pahse Smart Meter, please refer to 2.4.3 Smart Meter & CT Connection to check if the
connection and communication of Smart Meter is OK.
