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

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.

8 Work Modes
EM series inverters have the following main work modes based on different conditions:
Mode1：
Energy produced by the PV system priority for local load,
excess energy is used to charge the battery, finally
remaining is delivered to the grid.
Mode2：
If there is no PV, battery energy is used for local load
first, the grid also can supply when the battery capacity
is not enough.
Mode3：
If the grid is fault or there is no grid, the system can still
work, PV and batteries supply energy for local load.
Mode4：
The battery can be charged by the grid, time and power
of battery charging can be set up flexibly.

board). Example are electricity meters, primary overcurrent protection equipment and other equipment connected
directly to outdoor open lines.
Environment category definition
Outdoor : the ambient air temperature is -20~50°C, Relative humidity range is 4 % to 100 %, applied to PD3
Indoor unconditioned: the ambient air temperature is -20~50°C, Relative humidity range is 5 % to 95%,applied to PD3
Indoor conditioned: the ambient air temperature is 0~40°C, Relative humidity range is 5 % to 85%,applied to PD2
Pollution degree definition
Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by
condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or, dry, non-conductive pollution occurs which becomes conductive due to
condensation which is expected.
Pollution degree 4: Persistent conductive pollution occurs, for example, the pollution cause by conductive dust, rain and snow.
