INTRODUCTION INTRODUCTION
01
GoodWe EH series, also called hybrid or bidirecational solar inverters, apply to solar system with participa-
tion of PV, battery, loads and grid system for energy management. The energy produced by PV system
shall be used to optimize self-consumption, excess power charge battery and the rest power could be
exported to the grids. Battery shall discharge to support loads when PV power is insufficient to meet
self-consumption. If both PV power and battery power is insufficient, the system will take power form grid
to support loads.
Note: The introduction describes a general behavior of EH system.
The operation mode can be adjusted on GoodWe PV Master APP
based on the system layout. Below are the general operation based on
the system layout. Below are the general operation modes for EH
system.
The energy produced by the PV system is used to
optimize self-consumption. The excess energy is used to
charge the batteries, then exported to gird.
When grid fails , the system automatically switches to
Back-Up mode, the Back-Up load could be supported by
PV and battery.
Battery could be charged by grid, and charge time/power
could be set flexibly on PV Master APP.
When there is no PV, and the battery is sufficient , It can
supply the load with the grid together.
EH system normally has the following operation modes based on your configuration and layout conditions.
The EH series hybrid inverter of Jiangsu GoodWe Power Supply Technology Co., Ltd. (hereinafter called
as GoodWe) strictly comply with related safety rules for product design and testing. Please read and follow
all the instructions and cautions on the hybrid inverter or user manual during installation, operation or
maintenance, as any improper operation might cause personal or damage.

Prohibit to insert or pull the AC and DC terminals when the inverter is running.
Before any wiring connection or electrical operation on inverter, all battery and AC power must be
disconnected from inverter for at least 5 minutes to make sure inverter is totally isolated to avoid
electric shock.
The temperature of inverter surface might exceed 60℃during working, so please make sure it is
cooled down before touching it, and make sure the inverter is untouchable for children
Do not open inverter cover or change any components without GoodWe’s authorization, otherwise
the warranty commitment for the inverter will be invalid.
Usage and operation of the inverter must follow instructions in this user manual, otherwise the
protection design might be useless and warranty for the inverter will be invalid.
Appropriate methods must be adopted to protect inverter from static damage. Any damage caused
by static is not warranted by GoodWe.
PV negative (PV-) and battery negative (BAT-) on inverter side is not grounded as default design.
Connecting PV- or BAT- to EARTH are strictly forbidden.
PV modules used on the inverter must have an IEC61730 class A rating, and the total open-circuit
voltage of PV string/array is lower than the maximum rated DC input voltage of the inverter. Any
damage caused by PV over-voltage is beyond warranty.
The inverter, with built-in RCMU, will exclude possibility of DC residual current to 6mA, thus in the
system an external RCD (type A) can be used(≥30mA).
In Australia, the inverter internal switching does not maintain neutral integrity, which must be
addressed by external connection arrangements like in the system connection diagram for Australia
on page 16.
In Australia, output of Back-Up side in switchbox should be labeled ‘Main switch UPS supply’, the
output of normal load side in switch box should be labeled ‘main switch inverter supply’.
Any installation and operation on hybrid inverter must be performed by qualified electricians, in compliance
with standards, wiring rules or requirements of local grid authorities or companies (like AS 4777 and
AS/NZS 3000 in Australia).

Conduct Core Section Declaration For Back-Up Function
The below statement lays out GoodWe general policies governing the energy storage inverters of the
series ES, EM, SBP, ET, EH and BH.
1. For Hybrid inverters (Series ES, EM, EH and ET), the standard PV installation typically consists of the
connection of the inverter with both panels and batteries. In case of systems not connected to the
batteries, the Back-Up function is strongly not advised to use. GoodWe shall not cover the standard
warranty and be liable for any consequences arising from users not following this instruction.
2. Under normal circumstances, the Back-Up switching time is less than 10 ms (the minimal condition
to be considered as the UPS level). However, some external factors may cause the system to fail on
Back-Up mode. As such, we recommend the users to be aware of conditions and follow the instructions
as below:
1) Do not connect loads if they are dependent on a stable energy supply for a reliable operation
2) Do not connect the loads which may in total exceed the maximum Back-Up capacity
3) Try to avoid those loads which may create very high start-up current surges such as Inverter Air-condi-
tioner, high-power pump etc.
4) Due to the condition of battery itself, battery current might be limited by some factors including but
not limited to the temperature, weather etc.
Special Adjustable Setting
The inverter has filed adjustable setting like tripping point, tripping time, reconnect time, active and
invalid of QU/PU curves etc. by special firmware. Please contact GoodWe after sales for the special
firmware and adjust methods.
Connection For SPLIT Grid System
In SPLIT grid system, there is a solution allowing
inverter to work under On-Grid condition (Pic
25). But the export power and load power might
be detected inaccurately as the nominal output
power of inverter is 230V and there could be
loads of 110V or 220V.
Note：The absence of AC breaker on Back-Up side will lead to inverter damage if only electrical
short-circuit happened on Back-Up side. And Back-Up function cannot turn off under On-Grid
condition.
An external AC breaker (≥32A) is needed for Back-Up connection to be isolate when necessary.
Back-Up wiring connection process is as below

Smart Meter
2. One Smart Meter can only be used for one EH inverter.
3. CT must be connected on the same direction as the CT indicated.

2.5 DRED & REMOTE SHUTDOWN CONNECTION
DRED is used for Australia and New Zealand installation (also used as remote shutdown function in
European countries), in compliance with Australia and New Zealand safety requirements( or European
countries). And DRED device is not provided by GoodWe.
13
INSTALLATION INSTRUCTIONS MAMUAL OPERATION
The Smart Meter with CT in GoodWe product box is compulsory for EH system installation, used to
detect grid voltage and current direction and magnitude, further to instruct the operation condition of
EH inverter via RS485 communication.
Accepted loads as below:
• Inductive Load: 1.5P non-frequency conversion air-conditioner can be connect to back-up side.
Two or more non-frequency conversion air-conditioner connect to back-up side may cause UPS
mode unstable.
• Capacitive Load: Total power <= 0.6 x nominal power of model. (Any load with high inrush
current at start-up is not accepted.)
• For complicated application, please contact GoodWe's after service.
Declaration For Back-Up Loads
EH series hybrid inverters are able to supply over load output at its’ Back-Up. For details please refer
to the technical parameters of EH series inverter (4.3 section). And the inverter has self-protection
derating at high ambient temperature.
26
Note:
For a convenient maintenance, an DP3T
support could be installed on Back-Up and
On-Grid side. Then it is adjustable to support
load by Back-Up or by grid or just leave it
there (Pic 26).
Declaration For Back-Up Overload Protection
Inverer will restart itself as overload protection happens. The preparation time for restarting will be
longer and longer (max one hour) if overload protection repeats. Take following steps to restart
inverter immediately.
• Decrease Back-Up load power within max limitation.
• On PV Master →Adcanced Setting →Click “Reset Back-Up Overload History”
Make sure AC cable is totally isolated from AC power before connecting Smart Meter & CT.[6]
