Temp. too high
Excessive temperature. If the fault persists:
•
Make sure the spaces are sufficient around
the inverter.
•
Make sure no dirt or obstruction is present in the
fins of the heat sink.
•
Reinstall the UPS in a cooler location

N / A
Failure Temp Sensor. Temperature sensor
broken or not
connected.
If the fault persists, contact SolarEdge
support.

Fault Isolation
PV defective insulation. The inverter
has detected the PV solar panel is
not properly isolated from ground
currents. The insulation will be
checked each time the inverter
starts.
If the fault persists
•
Check the PV system for insulation and earth

equi error. phases
The monitoring hardware that
checks the balance of each phase
(L1-N and L2-N) has exceeded the
allowable limits
•
Check the network connection.
•
Check the GND wire connection.
•
Check the connections of L1, L2 and neutral.
•
Checking symmetrical load between L1 and L2.
•
Check with the operator of the local network.
