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. For example, your inverter operates at a
constant power of 4600 W for half an hour and then at a constant power of 2300 W for
another half an hour, it has fed 3450Wh 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 active power or watts to apparent power or volt amps. They
are identical only when current and voltage are in phase then 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 photovoltaic.
Wireless communication
The external wireless communication technology is a radio technology that allows the
inverter and other communication products to communicate with each other.The
wireless communication device is not standard. Require to order extral if you need it.

2.1 Product description and features
2.1.1 Product description
Growatt series photovoltaic inverters are used to convert the direct current generated by
photovoltaic panels into alternating current, and send it to the grid in a three-phase
manner. MID 17-33KTL3-X(1) series inverter can be connected to six strings(MID 36-
40KTL3-X can be connected to eight strings), has 3/4 maximum power tracking point
trackers, so suitable for connection 3/4 Set of arrays of different panels.
