Troubleshooting 
If the Matrix 2000 fails to operate properly after installation and setup, use the following tables 
to determine the probable cause(s) and solution(s) to resolve the error conditions. 
For unlisted error conditions, please contact your local dealer for technical assistance. See

No AC output and 
all LEDs are off. 
 
1. Check if input cables are all firmly connected 
to power source. 
2. Check if power source is switched on, or is 
low in power. 
No AC output. 
Both green and 
yellow LEDs flash. 
Inverter self-diagnosis takes a few seconds. LED 
then turns to a solid green. 
No AC output. 
Both yellow and 
red LEDs are on. 
Reduce the load to below 105% of the total 
power rating. 
No AC output, 
Red LED is on. 
1. Input wiring is reverse 
polarity. 
Check input cable polarity (positive to positive, 
negative to negative). 
Reboot the inverter by switching the input 
power source on and off. 
If the inverter fails to operate, return the inverter 
for service. 
3. Inverter output is shorted 
Turn off the input power source to remove all 
short circuits. 
1. Inverter fails to soft start 
Reboot the inverter by switching the input 
power source on and off. 
2. Inverter temperature is 
above the temperature limit. 
Leave inverter idle to cool down for few 
minutes. 
AC output exists 
with yellow LED 
flashing. 
Input voltage is out of 
operating range. 
Ensure input voltage is between 45V and 58V. 
Check if the dc source is connected. 
AC output exists 
with yellow LED 
on 
Load is over 100% but below 
125%. 
Reduce the load to below 105% of the total 
power rating. 
Inverter 
continuously 
delivers power, 
with red LED 
flashing slowly. 
 
Reboot the inverter system by switching the 
input power source on and off. 
If the fan is blocked, remove the cause. 
If the fan fails to operate, return the inverter for 
service.
