Back-up Output
AC Undervoltage
1. Excessive power
of connected load
2. Insufficient
energy on the DC
side or Bus leads
to low inverter
voltage
1. Confirm whether the connected load power is
within the rated range of the equipment.
2. Confirm if there is insufficient light or battery
power.
3. If it occurs frequently, please contact your
dealer or after-sales service center.
10
Cavity
Overtemperature
1. The inverter is
installed in a
place with poor
ventilation.
2. The ambient
temperature
exceeds 60
℃ .
3. A fault occurs in
the internal fan of
the inverter.
1. Check the ventilation and the ambient
temperature at the installation point.
2. If the ventilation is poor or the ambient
temperature is too high, improve the
ventilation and heat dissipation.
3. Contact the dealer or after-sales service
if both the ventilation and the ambient
temperature are normal.
11
Low Insulation
Res.
1. The PV string is
short-circuited
to PE.
2. The PV system
is in a moist
environment and
the cable is not
well insulated to
the ground.
1. Check whether the resistance of the PV
string to PE exceeds 50kΩ. If no, check the
short circuit point.
2. Check whether the PE cable is connected
correctly.
3. If the resistance is lower than default on rainy
days, please reset the ISO via SolarGo app.
Inverters for the Australian and New Zealand markets can
also be alerted in the following ways in the event of insulation
impedance failure:
1. The inverter is equipped with the buzzer: the buzzer sounds
continuously for 1 minute in case of failure; If the fault is not
resolved, the buzzer sounds every 30 minutes.
2. Add the inverter to the monitoring platform, and set the alarm
reminder, the alarm information can be sent to the customer
by emails.
12 DC Arc Fault
1. The DC terminal
is not firmly
connected.
2. The DC cable is
broken.
Read the Quick Installation Guide and check
whether the cables are connected properly.
13 CPLD Protection
CPLD protection
triggering fault
1. If it happens by chance, no manual
intervention is required.
2. If it occurs frequently, please contact your
dealer or after-sales service center.
