After the inverter is switched on, it takes a finite time for it to become ready to deliver
full power. hence, always switch on the load(s) after a few seconds of switching on the
inverter. Avoid switching on the inverter with the load already switched on. This may
prematurely trigger the overload protection.
when a load is switched on, it may require initial higher power surge to start. hence,
if multiple loads are being powered, they should be switched on one by one so that
the inverter is not overloaded by the higher starting surge if all the loads are switched
on at once.

before switching on the inverter, check that all the Ac loads have been switched off.
The on/off switch (a, fig. 7.1 or 7.2) on the front panel of the inverter is used to switch
on and switch off the Ac power output of the inverter. This switch operates a low
power control circuitry which in turn controls all the high power circuitry.

Please note that this switch is not switching the high power battery input circuit. Parts of
the Dc side circuit will still be alive even when the switch is in the oFF position. Hence,
disconnect the Dc and Ac sides before working on any circuits connected to the inverter.
when the inverter is switched on, the colored, 10 level lEd bar graph for dc input
voltage (d, fig. 7.1 or 7.2) will be lighted and the voltage at the input terminals will be
indicated. It should read between 12 to 13 volts if the batteries are fully charged.
Switch on the Ac load(s). The colored, 10 level lEd bar graph for dc input current /
output power (e, fig. 7.1 or 7.2) will show the current drawn by the inverter from the
batteries and the corresponding Ac output power in watts. The value of the current
drawn will be proportional to the Ac power drawn by the load. The voltage shown will
decrease slightly and this decrease will be proportional to the power drawn by the load

The colored, 10 level lEd bar graph (d, fig. 7.1 or 7.2) indicates the voltage at the dc
input terminals of the inverter. The voltage at the dc input terminals will always be
less than the voltage at the battery terminals due to drop in voltage in the battery side
cables and connectors. when there is no load connected to the inverter, the dc input
voltage at the inverter terminals will be almost same as the voltage at the battery ter-
minals. If the batteries are fully charged, the voltage display should read between 12 to
13 Volts. As the Ac power delivered by the inverter increases, the value of the dc input
