1 Technical documentation

The Pylontech Force H3X is a hybrid inverter with battery modules. The Reduxi Controller communicates with it over the local network via Modbus TCP. The IP address of the inverter is set in the Pylontech app, Modbus TCP is already enabled on the inverter.

2 Required equipment

  • Reduxi Controller (installed and online)
  • Pylontech Force H3X hybrid inverter, commissioned
  • Ethernet cable (CAT5e or CAT6) from the LAN (RJ45) port of the power control module to a router or switch
  • Smartphone with the Pylontech app and installer access
  • Laptop or tablet with internet access to configure the device in Reduxi

⚠️

Installer only The configuration of communication and system parameters must be carried out by an authorized installer. Use a wired LAN connection, wireless connections are not supported.

3 System overview & wiring

Connect the LAN (RJ45) port of the Force H3X power control module to your router or switch. The Reduxi Controller must be in the same network.

Connection From To Note
LAN (Modbus TCP) Reduxi Controller Router / switch Same network as the inverter
LAN (Modbus TCP) Force H3X, LAN (RJ45) port of the power control module Router / switch CAT5e or CAT6, up to 100 m recommended; port 502
LAN Router Internet Needed for the Reduxi Cloud and the app

✅

Use a fixed IP address Give the inverter a fixed IP address, see ⁠Point 4.1⁠. If the address changes, Reduxi loses the connection.

4 Configure the inverter

4.1 Set the IP address in the Pylontech app

The IP address cannot be configured on the inverter display. It is set only in the Pylontech app, which you can download from the Apple App Store or Google Play.

1
Open the app
Install or log in to the Pylontech app and open it.
2
Select the device
Select the corresponding Plant and Device.
3
Open the LAN settings
Go to Settings → Communication → LAN.
4
Enter a static IP address
Enter the network data that match your local network, for example IP address 192.168.1.50, subnet mask 255.255.255.0, gateway 192.168.1.1, DNS server 8.8.8.8. Your values depend on your network.
5
Save and restart
Save the configuration and restart the inverter so that the changes take effect.

4.2 Modbus TCP status

Modbus TCP is enabled by default on the Force H3X. No manual activation is needed. As soon as the LAN connection and the IP address are set up, Modbus TCP is available with these default parameters:

Parameter Value
Protocol Modbus TCP
Port 502
Transport Ethernet (LAN)

5 Log in to the Reduxi web interface

The device is added in the Configurator, the web interface of the Reduxi Controller. You do not add it in the Reduxi app itself or in the Reduxi Cloud. You can open it in two ways:

Recommended

📱
Reduxi app
Opens the Configurator through the tunnel connection, from anywhere.
💻
Web browser
In the same network as the controller, via its IP address or http://reduxi.local.
📱 5.1 Via the Reduxi app
1
Open the app and log in
Log in with your Reduxi account.
2
Open Reduxi devices
Tap the menu icon top left, then Reduxi devices, and select the location.
3
Switch on the tunnel connection
Switch on the tunnel and wait about 30 seconds.
4
Open the Configurator
Tap Open configurator. You are logged in automatically.

Reduxi app – Reduxi devices with tunnel connection

Reduxi devices with the tunnel switch

Reduxi app – Open configurator

Open configurator

✅

On a computer, away from the site In the Reduxi Cloud (reduxi.app) open the location, then Manage location → OEM devices → Activate tunnel connection, confirm with OK and wait about 30 seconds. Then click Go to controller. The Configurator opens in a new tab without a password.
💻 5.2 Via a web browser
1
Open the login page
In the same network, enter the controller's IP address or http://reduxi.local. The IP address is in the router's device list or in the app under Reduxi devices.
2
Log in
Username admin · Password admin (factory default). If it was changed during installation, use that one. This is not your Reduxi account password.
Reduxi Controller login screen
Login screen of the Reduxi Controller

This is what you should see:

Reduxi Configurator home screen with the device list on the left
Configurator home screen with the device list on the left

⚠️

Common stumbling blocks The tunnel needs about 30 seconds before the Configurator opens. The admin login is not your Reduxi account. reduxi.local only works in the same network as the controller.

6 Add the device to Reduxi

Open the Configurator first, see ⁠Point 5⁠. The device is added with the wizard in two steps.

6.1 Basic settings

1
Click + Add device
In the left menu the section Devices lists all devices (click it if it is collapsed). + Add device sits directly below the list. Do not use + Add EEBUS device.
2
Device type
Select Hybrid inverter.
3
Type
Select PylonTech Force H3X Hybrid.
4
Name and strategies
Enter a clear name, for example Pylontech Force H3X. Tick the strategies the inverter should take part in, then click Next.
Add device in the Configurator
+ Add device below the device list (marked in red)
Basic settings in the Configurator wizard
Basic settings: Hybrid inverter, PylonTech Force H3X Hybrid, name

6.2 Communication settings

The second step sets up the communication channel for Modbus TCP.

Parameter Value
Connection TCP/IP
IP The static IP address of the inverter from ⁠Point 4.1⁠. Scan for IP can search for it in the network.
Port 502 (default)
Extended IP recovery Leave switched on (default)
Inverter Modbus unit ID 2 (default)
ESS Modbus unit ID 1 (default)
Control mode Leave the default unless you need a different control mode
Is electricity meter installed? / Is internal PV installed? / Is external PV installed (other inverter)? Set according to your system. If external PV is installed, also enter its rated power.

Communication settings: IP, port, unit IDs and control mode

6.3 Test communication

Click Test communication at the bottom of the wizard. It checks the connection once and saves nothing. If you get a response, click Done. Only Done creates the device.

Test communication button

Failed test communication
Unsuccessful response: Unable to communicate with device

7 Check the readings

7.1 Check the readings

Open Devices → Pylontech … → Last measurements. The values of the inverter and the battery should update. If all values stay at 0, check the points in the Common issues table below.

Example of the last measurements
Example: Last measurements of a device (shown here for an energy meter)

7.2 Control behaviour

After the device has been added, it can take part in the Reduxi strategies you ticked in the wizard. How to define a strategy for dynamic prices and tariffs is described in Strategies for Reduxi controller. You can monitor the system in the Reduxi application.

✓ Summary

Preparation (Points 1–3): Check the manufacturer information, connect the power control module to the router or switch with a LAN cable and note the IP address plan.

Pylontech Force H3X (Point 4): Set a static IP address in the Pylontech app (Settings → Communication → LAN) and restart the inverter. Modbus TCP is already enabled.

Add to Reduxi (Points 5–6): Open the Configurator, add a Hybrid inverter of type PylonTech Force H3X Hybrid, enter IP, port 502, inverter unit ID 2 and ESS unit ID 1, run Test communication and click Done.

Go live (Point 7): Check the last measurements and select the strategies the inverter should take part in.

→ Common issues

Issue Solution
Test communication fails Check that the LAN cable is connected to the LAN (RJ45) port of the power control module and that the inverter and the controller are in the same network. Check the IP address (⁠Point 4.1⁠), port 502 and the unit IDs (inverter 2, ESS 1). Wireless connections are not supported.
The IP address cannot be changed on the inverter display The IP address can only be set in the Pylontech app: Settings → Communication → LAN (⁠Point 4.1⁠).
The new IP address does not take effect Restart the inverter after saving the LAN settings in the app.
The device goes offline after a router restart The IP address has probably changed. Use a static IP address on the inverter and enter it in Reduxi.
Open configurator does not open or stays empty The tunnel is not active yet. Wait about 30 seconds and check that the controller is online.
Login with admin is rejected The password was changed during installation. Ask the installer. The Reduxi account password does not work there.
reduxi.local does not load You are not in the same network. Use the IP address or the tunnel.
Communication test fails, device offline Check reachability, IP, port 1502 and unit ID 71, and that Modbus is enabled on the inverter.
