FEATURES AND BENEFITS
The inverter can transfer the spare capacity of AC power from one phase to the more loaded second phase. In practice, this means that the asymmetry on one phase can reach up to 200% of the rated power, i.e. for example 5 kW to one phase, instead of the usual 3.3 kW. This will significantly improve the user's self-consumption from stored or directly harnessed solar energy. Super Spillover Asymmetry (SPA) is not available for the SolaX Hybrid G4 12.0 and 15.0 models.
Often, hybrid inverters setup for overflow operation have trouble zeroing, especially at low draws or demands. The SOLAX G4 handles this excellently and tightens the unloaded phases to 8-14W.
Custom internal contactors that allow switching between AC OUT and EPS OUT without using an external EPS Box. Thus, the EPS output remains energized at all times and power source switching occurs in less than 10ms, which is sufficient for continuous operation of almost all applications.
SOLAX G4 will especially please technology installers. In addition to quick installation within 30 minutes, the inverter does not require mains or sunlight for start-up and initial setup. The internal voltage from the battery can be used to completely revitalise the system and thus flexibly schedule the work.
SOLAX G4 in power ranges from 5 to 15 kW (AC) and is loadable up to 18 kWp on the PV-module side. It is also suitable for smaller industrial applications. For even greater demands, the function of parallel operation of up to 10 inverters has been retained (tests are still currently underway here).
The SOLAX G4 has a potential-free output relay to signal an excess. This helps the inverter to use the maximum available energy and can switch any appliance in the house. An easy start in combining the photovoltaic sector with home heating or water heating or electromobility. This allows you to set adjustable parameters for the function in the inverter in time or in connection with SOC batteries.

FAQ
We have two options to connect the wifi Dongle to SolaX cloud.
1. Using a laptop and the web interface
- The dongle connected to the inverter broadcasts a wi-fi network named "wifi_Sxxxxxxxxx" (Sxxxxxxxxx is the registration number of the dongle)
- Connect to this network using the notebook in the wi-fi network connection section of the notebook model
- Open a web browser and enter the following address in the URL bar of the search engine: 5.8.8.8, if the dongle does not respond use the address 192.168.10.10
- Username: admin
- Password: module registration number having the format "Sxxxxxxxxxxx"
- Select the SSID of the network you want to connect the dongle to + enter the password of the wifi network. Then press the Save button.
- After the reboot, the wifi dongle is connected to the given network, we can check by logging into the dongle again according to the previous instructions, and check if the dongle has been assigned an IP address in the IP address entry.
2. Using the app on your mobile phone
- Download the SolaX cloud app from the App store or Google play
- Create/have created an end customer account

- Press Next button
- Done ?
Note: Wi-fi dongles only support 2.4GHz networks with WPA2 encryption, the network name should not contain Czech accents, you must have location + data enabled on your mobile device.
By default, the DataHUB 1000 does not treat the state when communication breaks down and export control is set.
If I want the inverters to stop working when either the communication with DataHUB 1000 fails or the meter communication fails I have to make the following settings:
- Modbus opcode: Write single register
- Register start adress: 6152
- Number of registres: 1
- Value of write operation: 1
- Modbus opcode: Write single register
- Register start adress: 6153

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)

Newly added to the SolaX hybrid G4 inverter is a function for modifying the logic of emergency disconnection of the inverter from the grid known as the SHUT DOWN function or 0/100% regulation. There are now 3 modes to choose from:
1. Battery and inverter power disconnect function
When the potential free connection of pin 1+2 on the COM port is made, the battery / BMS master contactor will be disconnected, thus disconnecting the battery system from the inverter and also forcefully disconnecting the inverter from the distribution network.
Setup as follows: advanced menu - shut down - function control - use COM
Wiring:
2. The function of forcefully disconnecting the inverter from the grid, keeping the battery charged
This function is located on the SHUT port of the inverter and pin 4+6, when these pins are connected potential-free, the inverter is forcefully disconnected from the distribution network, but the battery charging function is maintained.
Settings: advanced menu - shut down - wait charge mode - Enable
Wiring:
3. Inverter power disconnect function from the mains, no battery usage
This function does not need to be set in any way in the inverter, and is active by default on the SHUT port and pin 4+6 in a potential-free connection. When this function is activated, the inverter is forcefully disconnected from the distribution network and also does not charge the battery.
Wiring:
We have two ways to find out the currently installed version in a SolaX 4th generation hybrid inverter:
- Directly from the display in the inverter menu and the About section , then select Internal code:
The first double digit (27) shows us the DSP version in our case 1.27 and the last double digit (26) the ARM version in this case 1.26.
- By locally connecting the SolaX cloud application on the mobile device:
Procedure:
1. On the mobile device, connect to the inverter's broadcast wifi network, which has the form "wifi_Sxxxxxxx".
2. Open the SolaX Cloud app and connect locally.
3. Scan/fill in the registration code of your wi-fi dongle:
4. Select the "Data" icon on the bottom right and then about, then you will see the DSP and ARM versions:
Newly implemented in the Solax Hybrid G4 inverter is the Pgrid Bias function, which was specially developed for the Czech market depending on the type of PP contract and the preferences of the PV owner.
- Pgrid Bias = DISABLE – the inverter regulates to the precisely set value.
Example: Export Control = 0 W and Pgrid Bias = DISABLE. In this combination of settings, the inverter will regulate to 0 W, but it may happen that in the event of a sudden request to cover a large amount of energy - for example, switching on the heating spiral, the inverter will take energy from the grid for a few moments before fully covering this load. Analogously, it also applies in the opposite case, when switching on this high load, the inverter can send a small amount of energy to DS before it downregulates to 0 W.
Conclusion: This setting is suitable for customers who are allowed to flow into the grid and are willing to accept occasional consumption from the grid due to fast switching of heavy loads if they have set Export Control = 0 W. In other cases where Export Control = any positive value should Pgrid Bias also be set to DISABLE.
- Pgrid Bias = INV – the inverter still draws approx. 40 W from the grid
Example: Export Control = 0 W and Pgrid Bias = INV. In this combination of settings, the inverter will still draw (consume) energy from the network of approx. 40 W so that in the event of a sudden disconnection of a high load, it eliminates the sending of energy to the DS, as the inverter creates a so-called reserve for this possible overflow with this drawing.
Conclusion: This setting is suitable for customers who do not have any network overflow allowed. This setting works more efficiently using original measuring current transformers.
- Pgrid Bias = GRID – the inverter still sends approx. 40 W to the grid
Example: Export Control = 0 W and Pgrid Bias = GRID. In this combination of settings, the inverter will still send approx. 40 W to the network, so that in the event of a sudden switch-on of a high load, e.g. a heating spiral, there will be no short energy withdrawal from the DS before the inverter fully covers this load.
Conclusion: This setting is suitable for customers who, although supply to the grid is allowed, but want to set Export Control = 0 W and at the same time do not want the inverter to take energy from the DS for a short time in the event of a sudden switching on of a high load.
