Glossary
AC
Abbreviation for "Alternating Current".
DC
Abbreviation for "Direct Current".
Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or
MWh (megawatt hours). The energy is the power calculated over
time. If, for example, your inverter operates at a constant power
of 20,000 W for half an hour and then at a constant power of
10,000 W for another half an hour, it has fed 15 000Wh of
energy into the power distribution grid within that hour.
,
Power
Power is measured in W (watts), kW (kilowatts) or MW
(megawatts). Power is an instantaneous value. It displays the
power your inverter is currently feeding into the power
distribution grid.
Power
rate
Power rate is the radio of current power feeding into the power
distribution grid and the maximum power of the inverter that can
feed into the power distribution grid.
Power
Factor
Power factor is the ratio of true power or watts to apparent power
or volt amps. They are identical only when current and voltage are
in phase than the power factor is 1.0. The power in an ac circuit is
very seldom equal to the direct product of the volts and amperes.
In order to find the power of a single phase ac circuit the product
of volts and amperes must be multiplied by the power factor.
PV
Abbreviation for photovoltaics.
6.1 Display and messages

6.1.2 LCD control
The LCD display's backlight automatically turns off after 30 seconds to save the
power. The display on the inverter can be control by Knock on the front of it.
