G.2 The Transfer system (P-06)
When an AC voltage is present at the AC IN of the Invertek, the “AC IN” LED is lit.
When this voltage matches the Parameter P-06 value set, and the frequency is
between 44Hz and 65Hz, then this power is transferred directly to the AC load and
the battery charger section of the Invertek. The “TRANSFER” LED is lit to indicate
this has happened. The inverter is then switched off and the battery charger
switched on. This process is automatic and should not be noticed by the load, at
worst a slight flicker may be seen in lights.
The maximum current of the Bypass switch is (60A/DAI-3000C-xxxx) or
(30A/DAI-1500C-xxxx). That means through this system. AC loads of up to a
maximum 7000 W (DAI-3000C-xxxx) or 3500W (DAI-1500C-xxxx) can be operated.
When the Battery Charger is working, part of this power is used for the charging
according to the power sharing settings.
The Transfer system is protected against overload with an automatic breaker
on the AC Input side of the Invertek. If the system has been overloaded
the Input breaker will pop-out. To put the automatic safety system back in
to operating you must push this breaker for reset.
Note: In Inverter operation, The Invertek generates a True Sinewave and quartz
stabilized output voltage. However, when the Invertek is transferring power from
the grid or a generator the voltage and quality of the power running the AC load
will be the same as that coming from the grid or generator. The Invertek cannot
modify the incoming AC supply.
Setting the transfer voltage threshold (P-06)
The voltage threshold of the transfer can be adjusted between 150 to 230V with
the Parameter P-06. This value is set at 150V AC in the factory. The
majority of appliances can work on this voltage. When the Input voltage reaches
the selected value on the P-06, the inverter switches off and the AC
INPUT goes directly to the AC OUTPUT. When the voltage INPUT is 20V less
than the value set, the transfer of power is stopped and the OUTPUT is switched
back to the inverter.
G.3 The Solar charge regulator (option)
The Invertek has an optional built in Solar Charge Regulator. To charge the
batteries, Solar modules can be connected to the terminal SOLAR IN +/-. The
in-built regulator is a Shunt regulator with a maximum input current of 30A for all
series products. The operating voltage of Solar modules to be connected must
match the actual operating voltage of the Invertek and never exceed the max. rated
value.
