Power inverter is
now of course a need based device to avoid unwanted power cuts. Grid tie power inverter
is one of the easiest options to get power supply round the clock without any
interruption. The term ‘grid-tied’ means that the
house is still connected to the local utility power grid. Grid-tied inverters
change the direct current (DC) from the power source and turn it into the same
kind of alternating current (AC) that is supplied by the electric company. This is the reason why this is
popularly known as DC to AC power
inverter. The mechanism
behind the grid tie power inverter is that it doesn’t require any special boxes
to connect to the mains rather only requires to be plugged into wall socket.
These are quite safe for the users and when the power fails the grid tie
automatically disconnects.
Basing on the
diversified technology these inverters are of various types. So before selection
of a grid tie inverters, following points should be kept in mind.
·
Whether rated output power provided in
watts or kilowatts
·
Peak efficiency: It indicates the highest
level of efficiency that the device can achieve.
·
Maximum input current: i.e the maximum
amount of direct current that the device can utilise.
·
Start voltage: that indicates the
minimum DC voltage required for the device to turn on and begin working.
·
The protection that the device has against
water.
