Equipment:

• Diesel generator set with the same or higher output as the installation (KRAFTWELE KW9800 3F ATS)
• ATS control
• CT
• Smart meter (Chint DTSU666/CT)
• WARNING! ULTRA inverters require a right-hand phase sequence, Hybrid G4 does not require this

Control Methods:

1. Using ATS only - currently only for Hybrid G4!!

In this case the inverter does not communicate directly with the genset, but the ATS of the genset monitors the voltage on the GRID side. The moment there is a voltage failure on the selected phase of the AC grid, the ATS starts the aggregate.

• On the grid side, a smart meter (direct metering/direct metering) is required The communication address of this meter must be "2".
• CT coils are required to protect the generator against backflow. (CTs use an analog signal which is faster than the digital signal used in the smart meter.

ATS wiring only:

The wiring procedure in the manual must be followed. Here is an example for our tested KRAFTWELE KW9800 3F ATS.

The inverter is connected from the Grid terminals to the ATS to the OUTPUT terminals. The distribution grid is connected to the House Net terminals and the output of the diesel generator set is connected to the Generator terminals. The SMART METER is connected between the distribution network and the ATS.

Between the ATS and the GRID terminals of the inverter, the CT coils are connected towards the GENERATOR! These coils are typically placed just after the ATS so that the coils sense the consumption at the point of installation that is connected after these coils, it is very important that the arrows of the coils point towards the distribution network, failure to do so can lead to the destruction of the diesel-generator.

On the ATS box there is a button with the AUTO / MANUAL option

• When using the ATS function, the button is in the AUTO position
• When using the DRY CONTACT function, the button is in the MANUAL position

ATS setting only:

• MaxChargePower - Maximum battery charging power (0~30000, 5000W default)

• Char&Disc Period - Same function as in inverter charging time setting

• Charge from Gen → Charge battery to - How much SOC battery to be charged from generator (10~100, 10% default)
• Charge from Gen → Charge battery to

2. Using Dry Contact Hybrid G4/Ultra

The inverter is directly connected via DO contact (COM port pin: 7,8 for Hybrid G4 or DIO port pin 1+2 for Ultra) to the ATS and gives a signal when the ATS should start the generator.

• On the network side a smart meter (direct/indirect measurement) is required and the communication address must be "2".
• CT coils are required to protect the generator against backflow. (CTs use an analog signal that is faster than the digital signal used in the smart meter.
• From the COM port on the inverter (pin 7,8) or the DIO port (pin 1+2) for the Ultra, route the signal to the ATS switch (Auto/manual button) where a connection needs to be made so that the ATS can be controlled by the inverter.

DRY CONTACT wiring (Hybrid G4):

DRY CONTACT (Ultra) wiring:

Uses Pin 1+2 from the DIO terminal block.

Connecting DRY CONTACT to the logic of a diesel generator e.g. KRAFTWELE KW9800 3F ATS

DRY CONTACT setting (Hybrid G4/Ultra):

• MaxChargePower - Maximum battery charging power (0~30000, 5000W default)
• Char&Disc Period - Same function as in inverter charging time setting
• Charge from Gen → Charge battery to - How much SOC battery to be charged from generator (10~100, 10% default)
• Charge from Gen → Charge battery to
• External Gen = Immediately - Immediate start of generator when mains voltage changes
• Charge from Gen→Charge battery to - How much SOC battery to be charged from generator (10~100, 10% default)
• MinRestTime - Minimum time between generator starts
• HoldGenMinPower (hybrid G4 only) - Minimum generator power

CT/Meter setting (Hybrid G4/Ultra): (applies to both ATS and Dry Contact)

NAV_SOLAX_Remote_shutdown_solution (EN)

A new feature has been added to the SolaX Hybrid G4 inverter: the function for adjusting the emergency disconnection logic of the inverter from the grid, known as the SHUT DOWN function or 0/100% regulation. You can now choose from 3 modes:

1. Function for power disconnection of the battery and inverter

2. Function for power disconnection of the inverter from the grid while maintaining battery charging

3. Function for power disconnection of the inverter from the grid without using the battery

This function does not require any configuration in the inverter and is active by default on the SHUT port and pins 4+6 with a potential-free connection. When activated, the inverter is power-disconnected from the grid and does not charge the battery.

This operating mode optimizes the operation of your PV plant based on your predefined scenarios at defined time periods.

TOU allows users to set the behaviour of the PV plant according to different scenarios in defined time periods such as weekends, weekdays, holidays, thus making the operation of your inverter more efficient.

Currently, the following inverters are supported to set the TOU operating mode:

• X1-Hybrid G4
• X3-Hybrid G4
• X3-Ultra

The above inverters must contain the latest FW of both the inverter and the communication module.

After connecting your black 3.0 wifi dongle, does the message "Aging mode" appear on the inverter and the inverter does not work? We know the solution!
Please restart the whole system so that the inverter goes to normal mode. (disconnecting the inverter from the distribution network, switching the DC switch to the OFF position, turning off the main circuit breaker on the batteries)
After rebooting the entire system, upload the latest FW to your chosen black 3.0 wifi module.

You can find the procedure below:

1. Download latest firmware for black wifi dongle here >>
2. Unzip the downloaded file
3. Connect your laptop to the broadcast wifi signal with a dongle ("wifi_Sxxxxxxxxx")
4. Open the browser and enter the IP address 5.8.8.8 if the wifi dongle does not respond then 192.168.10.10
5. Enter login information: username: admin, Password: dongle registration number (Sxxxxxxxxx), for older models admin
6. In the System tab, press the "choose file" button and select the downloaded and unzipped file from step 2

7. Press the start button

After uploading the latest wifi dongle firmware, the inverter will go into normal working mode.

External ATS function

If you want to have the EPS output of the inverter always under voltage, please set the External ATS function to Disable in the Advanced menu.

Do you own a SolaX inverter and wonder which communication dongle is compatible with it? We have a solution for you!

Remove the protective cover from the dongle connector and check its shape.

1) If you see a recess with a USB port, then the suitable type for you is the WHITE dongle Pocket WiFi 2.0 – item code (B-210-1000)

2) If you see a black plastic extension with a USB port, then the suitable type for you is the BLACK dongle Pocket WiFi 3.0 – item code (B-210-1014)
