HYBRID INVERTER | Installer Manual
63
Check each bond on the
solar panels
Check the VOC does not
exceed 480V
Ensure both MPPTs are
balanced
Measure the supply volt-
age check it matches the
settings of the inverter
If it falls out of the setting
range it will cause the in-
verse shut down and alarm
See Grid Setup page
Check the battery charge
and discharge is within
the C rating of the battery.
Too high will damage the
battery
Check the battery BMS is
communicating with the
inverter
This is the heart of the
system this controller
everything
Ensure you are familiar
with this, if you fully under
-
stand the controller you
will fully appreciate the ca
-
pabilities of there inverter
See section ‘Program
Charge / Discharge Times’
This is for paralleling sys
-
tems, and wind turbine
If paralleling inverters in
3 Phase check you phase
rotation before switching
on the AC Load, in 3 Phase
the output voltage will
increase across phase to
400V
If using a wind turbine
please ensure you have
the correct limiting resis-
tor, caps and rectifier
Familiarize yourself with
common fault codes
6.3. GDFI Fault
Before the inverter connects to the Grid, it will detect the impedance (effective resistance) of the solar PV
+ to Ground, and the impedance of the solar PV - to ground. If any of the impedance values are less than
33kΩ, the inverter will not connect to the Grid and will report an error F24 on its LCD.
7. MAINTENANCE
The inverter is low maintenance. However, it is important that at least twice a year (for dusty environments
this may need to be carried out weekly) all the cooling fans, air ducts are cleaned and dust free.
Check if there are no fault codes and Lithium battery communication is correct.
Weekly cleaning statement: Suggest micromesh filters as an available option, micro ants here are a real
problem.
