1 Introduction

The EM series inverters (hybrid) are bidirectional which apply to PV system with battery to store energy.
Energy produced by the PV system is used to optimize self-consumption; excess energy is used to charge the batteries, and then feed
into the public grid when the PV energy is adequate,
When PV energy output is insufficient to support connected loads, the system automatically discharge energy from the batteries if
battery capacity is abundant. If the battery energy is insufficient to meet own consumption requirements, electricity will be drawn
from the public grid.

EM series inverter is design for both indoor and outdoor use.The

2 Important Safety Warning

Before using the inverter, please read all instructions and cautionary markings on the unit and this manual. Store the manual where

it can be accessed easily.

The EM series inverter of Jiangsu GoodWe Power Supply Technology Co. Ltd. (hereinafter referred to as GoodWe) strictly conforms to

related safety rules in design and test.

Safety regulations relevant to the location shall be followed during installation, operation and maintenance.

Improper operation may have a risk of electric shock or damage to equipment and property.

2.2 Safety

● Installation, maintenance and connection of inverters must be performed by qualified personnel, in compliance with local electrical

standards, wiring rules and the requirements of local power authorities and/or companies (for example : AS 4777 and AS/NZS

3000 in Australia).

● To avoid electric shock, DC input and AC output of the inverter must be terminated at least 5 minutes before performing any

installation or maintenance.

● The temperature of some parts of the inverter may exceed 60℃ during operation. To avoid being burnt, do not touch the inverter

during operation. Let it cool before touching it.

● Ensure children are kept away from inverters.

● Do not open the front cover of the inverter. Apart from performing work at the wiring terminal (as instructed in this manual),

touching or changing components without authorization may cause injury to people, damage to inverters and annulment of the

warranty.

● Static electricity may damage electronic components. Appropriate method must be adopted to prevent such damage to the

inverter; otherwise the inverter may be damaged and the warranty annulled.

● Ensure the output voltage of the proposed PV array is lower than the maximum rated input voltage of the inverter; otherwise the

inverter may be damaged and the warranty annulled.

● When exposed to sunlight, the PV array generates dangerous high DC voltage. Please operate according to our instructions, or it

will result in danger to life.

● PV modules should have an IEC61730 class A rating.

● If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be

impaired.

● Completely isolate the inverter before maintaining. Completely isolate the inverter should ：Switch off the DC switch, disconnect

the PV terminal, disconnect the battery terminal, and disconnect the AC terminal.

● Prohibit to insert or pull the AC and DC terminals when the inverter is running.

● In Australia, the inverter internal switching does not maintain the neutral integrity, neutral integrity must be addressed by external

connection arrangements like the example proposed in the diagram 4.10.

● In Australia, the output of backup side in switchbox should be labeled 'main switch UPS supply', the output of normal load side in

switchbox should be labeled 'main switch inverter supply'.

● Don’t connect EM series in the following ways:

①Back-up port should not be connected to grid;

②Back-up port should not be connected in parallel;

③The single PV panel string should not be connected to two or more inverters.

3.3 Selecting The Mounting Location

Mounting location should be selected based on the following aspects:

n

at

● The install
dimensions.

● Mount on a solid surface.

● Select a well ventilated place sheltered from direct sun radiation.

● Install vertically or tilted backward by max 15°. The device cannot be installed with a sideways tilt. The connection area must point

downwards. Refer to Figure 3.3-1.

In order to achieve optimal performance, the ambient temperature should be lower than 45 °C.

●

● For the convenience of checking the LED lights and possible maintenance activities, please install the inverter at eye level.

● Inverters should NOT be installed near inflammable and explosive items. Any strong electro-magnetic equipment should be kept

away from installation site.

● Product label and warning symbol shall be clear to read after installation.

● Please avoid direct sunlight, rain exposure, snow lay up when install.
