WARINING

Make sure that the device is powered off before any operations.
Ensure the cables are connected tightly, securely, and correctly. Inappropriate wiring may cause poor contact or damage the device.
Additional circuit breakers are recommended on the voltage input side to avoid personal injury or device damage.
Specification of the protective fuse should be 0.5A.
In areas at risk of lightning, if the device cable exceeds 10m and wired without grounded metal conduits, you are recommended to use an external lightning protection device.

Check before Power-on

No.	Check Item
1	The product is firmly installed at a clean place that is well-ventilated

and easy- to-operate.
2| The input power cables, CT Cables, and communication cables are connected correctly and securely.

Installing the Meter and Cable Connection

NOTICE

The meter is installed on a rail, and should not be installed outdoors.
When operating the meter, use insulation tools and wear personal protective equipment to ensure personal safety.

Installing the Meter and Cable Connection

Connect CT cables

NOTICE

Requirements for the external CT specifications:
1. Choose nA/5A for the current transformation ratio of the external CT. (n: CT primary input current value between 200 – 5000, which is chosen by the user according to the actual conditions.
5A: CT secondary output current.)
2. Sampling error for the CT current ≤ 1% (0.5, 0.5s, 0.2, 0.2s is recommended).
3. CT bore size must be greater than the outer diameter of AC power line to make sure the AC power line can be inserted through CT.
4. It is recommended to choose the CT with 16AWG cable.
5. See the instructions provided by the respective manufacturer for specific CT wirings to ensure that the direction of the connections is correct and that they are functioning properly.
An incorrect inlet or direction from the external CT to the meter cable can cause damage to the device or incorrect acquisition of data.
Do not tamper with the cables that are pre-installed with the meter.
The direction of the external CT is from P1 end to P2 end, and the corresponding AC power line direction is from inverter side to grid side.
It is recommended to add an overcurrent protection device (rated current 0.5A) to the voltage input terminal (L1/L2/L3) of the meter.

Wiring System

System comprised of a single three-phase unit

System comprised of multiple three-phase units

Commissioning

Power ON

Step 1 Connect the meter cables.
Step 2 Power on the inverter and make sure that the inverter is working normally. Then the meter is powered on.

Commissioning the Meter

Set the CT parameters using the SolarGo APP (system comprised of a single threephase unit,with the Export function enabled)

When the GM3000C is used with the Inverter such as BTC series or ETC series etc., please refer to the corresponding user manual for CT-related parameter settings.

SolarGo App

NOTICE

Before setting the parameters, make sure that:

The DC side of the inverter is powered on, but no output on the AC side.
The SolarGo APP has been downloaded from Google Play or App Store.
Communication is functioning properly between SolarGo APP and inverter.
Please use the initial password when logging in for the first time, and change it as soon as possible to one that is memorable for you. To keep your account secure, it is recommended to change your password regularly.

Commissioning the Meter

Set the CT parameters using ProMate (system comprised of multiple

inverters)

NOTICE

Before setting the parameters, make sure that:

Both EzloggerPro and GM3000C is powered on.
GM3000C is correctly connected to COM4 of EzloggerPro via RS485.
The Ezlogger Pro Promate software has been downloaded from GOODWE’s official website and installed on the computer.
ProMate is connected to EzLogger Pro successfully. For detailed procedures, refer to the EzLogger Pro Series User Manual.

Descriptions of the Export Function.

$Set the CT parameters using ProMate $system comprised of multiple inverters$$

Total Capacity: Set according to the total capacity of the PV station.
Power Limit: Set according to the target power that needs to be fed into the grid.
Ratio of CT: Set according to the CT transformation ratio.
