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.

The inverter must be connected to the AC grounding conductor of the power

distribution grid via the ground terminal (PE) .

Because of the transformerless design, the DC positive pole and DC
negative pole of PV arrays are not permitted to be grounded.

WAR NI NG

According to the relevant provisions of IEC 61643-32 "Connecting to photovoltaic
devices surge protectors - selection and use of guidelines", whether for household or
commercial photovoltaic power plants, it is necessary to ensure the implementation of
lightning protection measures for photovoltaic systems.

The lightning protection measures for photovoltaic systems shall be
carried out in accordance with the corresponding national
standards and IEC standards. Otherwise, photovoltaic devices
such as components, inverters and power distribution facilities may

WAR NI NG

be damaged by lightning.
In this case, the company does not carry out warranty and assumes
any responsibility.

A. When the safety distance S is satisfied:
The position ①③ of the figure should be equipped with a lightning protection module.
In general, it is recommended to install Type II in position ① and Type I i n po si ti on ③.
B. When the safety and safety distance S is not met:

In addition to position 3, Type I lightning protection module should be installed in
Figure ①②④.
3）The lightning down conductor and the equipment ground wire eventually sink at a
total ground point, but the two cannot share the wire. That is, the equipment grounding

wire should be pulled separately, and the wire diameter requirement >6mm² when the
safety interval distance S is satisfied.

4）About the above lightning protection lightning receptor system related design
reference GB/T 21714.3-2015.

6.6 Active p ower contr ol with smar t meter , CT or ripp le control s ignal

The position of export limitation CT or Meter must between the
Inverter & Load and gird.

Information

This series inverter has integrated export limitation functionality. To us e th is f un ct io n,
you can connect smart meter or CT. The primary aperture is 10mm,output cable length
is 5m . The arrow on the CT mus t po in ti ng t ow ar ds t he i nv er te r.

Multiple inverter combination is not suitable in Australia.

1）It is generally recommended to install lightning protection devices (such as
lightning rods / lightning protection belts and down conductors) to prevent lightning

Fig 6.14

from hitting the PV array.
2）Lightning protection devices and down-conductors and related equipment in
photovoltaic systems (including photovoltaic panels, inverters, cables, power

distribution equipment) should maintain a safe separation distance S.
Suggested value of S: According to the general 5 storey height (about 15m) building
roof, S takes 2.5m enough, this distance can be simplified according to the inverse
relationship of the floor height.
