STS Troubleshooting
Error Condition Possible Cause Recommendation
No AC output and
all LED off.
Lack of input power 1. Check if input cables and bus bars are all
firmly connected to power source.
2. Check if inverter output or Mains AC are not
yet switched on, or is low in power
Priority is On line,
STS AC output is
normal but with
yellow LED on.
STS AC input source is from
inverter. The inverter is in
normal status, but the utility
line is in abnormal status.
Check AC Mains connection and status.
Priority is On line,
STS AC output is
normal but with
green LED flash at
1Hz.
STS AC input source is from
utility, the inverter is in
normal status; Maybe the
current load is out of the
capability of inverter, or the
inverter is just from abnormal
status back to normal.
Please refer to inverter trouble shooting guide
Priority is On line,
STS AC output is
normal but with
green LED flash at
1Hz, and yellow
LED on.
STS AC input source is from
utility, and inverter is in
abnormal status
Please refer to inverter trouble shooting guide
No AC output,
yellow LED is on.
Both inverter and utility AC
source are in abnormal status
Check AC mains and inverter output.

yellow LED flash
at 2Hz.
The relay of utility power side
is broken and can not form
close circuit
Turn MBS to mains or inverter bypass mode,
maintain the STS module
