Key Features
Dual Connectivity — WiFi 2.4 GHz and Wired Ethernet in One Dongle
The Pocket WiFi+LAN provides both wireless and wired network connections from a single device. WiFi (2.4 GHz, up to 50 m radius) works for most straightforward installations where the inverter and router are in the same building. The wired Ethernet port (10/100 Mbps RJ45) provides a fundamentally more stable and interference-free connection for installations in garages, outbuildings, lofts or any location where thick walls, distance or competing 2.4 GHz signals compromise WiFi reliability. Having both options in one dongle means the installer can choose the method that suits each specific site without stocking two separate SKUs.

10-Second Live Data Refresh via SolaXCloud
The standard data upload interval is 5 minutes, but the SolaXCloud live monitoring view updates every 10 seconds when actively viewed in the app or web browser. This means real-time tracking of: current PV generation (W), battery state of charge (%), grid import/export (W), household consumption (W), and inverter operating mode. Daily, weekly, monthly and annual generation charts are automatically compiled. For systems with battery storage, the live view shows battery charge/discharge rate and usable capacity.

Offline Data Storage and Automatic Resume
When the internet connection is lost — whether due to a router reboot, ISP outage or temporary network disruption — the dongle buffers monitoring data locally and uploads the gap automatically when connectivity is restored. This prevents holes in the monitoring history that would otherwise appear as zero-generation periods in the cloud data. For homeowners claiming SEG export payments or tracking performance against a feed-in tariff estimate, a continuous monitoring record is important for year-end performance reviews and warranty claims.

Modbus TCP Support — Local API for Home Automation
The Pocket WiFi+LAN supports Modbus TCP, enabling direct local network communication between the inverter and home automation platforms that support Modbus: most notably Home Assistant via the SolaX Modbus integration. Modbus TCP allows local polling of inverter registers without relying on the SolaXCloud servers, giving lower latency, offline operation and greater control flexibility. This is an increasingly important feature for homeowners integrating solar, battery and EV charging into a unified home energy management system. IEEE 2030.5 smart inverter grid protocol support is also included for utility-compatible smart grid communication.

IP65 — Fully Dust-Tight and Water-Jet Proof
The dongle is rated IP65: fully dust-tight (6) and protected against water jets from any direction (5). This makes it suitable for inverters installed in garages, utility rooms and plant areas where dust and occasional water splash are a realistic risk. The dongle’s connection to the inverter’s DONGLE port is sealed once screwed home. IP65 is a higher protection rating than many competing monitoring dongles that carry only IP20 or IP40.

Plug & Play Installation — No Tools, No Wiring, No External Power
Installation takes under 5 minutes. Switch off the inverter, remove the DONGLE port cover, insert the Pocket WiFi+LAN and secure. For Ethernet: screw off the cable entry component, pass the Ethernet cable through, and crimp an RJ45 connector inside the housing before securing. The dongle is powered entirely from the inverter’s DONGLE port (5 V, 200 mA) — no mains connection or USB adapter required. Setup is completed via the SolaXCloud app on a smartphone by scanning the dongle’s registration QR code.
Plug & PlayPowered from inverterNo tools for WiFi setup
Once connected, the inverter is visible on SolaXCloud (solaxcloud.com and mobile app). The platform provides: real-time and historical performance data; energy flow diagrams (PV, battery, grid, load); remote inverter settings changes; remote firmware updates (OTA); email-based performance reports (daily/weekly/monthly); and fault/alarm notifications. Installers and distributors have their own SolaXCloud portal view for managing multiple customer sites, monitoring fleet performance and pushing firmware updates remotely. The monitoring service is free with no subscription fee.

Frequently Asked Questions
What is the difference between the Pocket WiFi+LAN and the Pocket WiFi V3.0-P?
The Pocket WiFi+LAN (this product) supports both wireless WiFi and wired Ethernet. The Pocket WiFi V3.0-P supports WiFi only, but comes with an external antenna for improved range. The WiFi+LAN is the better default choice because it covers both scenarios: use WiFi for a quick setup, or run an Ethernet cable later if the WiFi signal proves unreliable. The WiFi V3.0-P is better if you specifically need the external antenna for a long-range wireless connection and have no interest in wired fallback.
Why use Ethernet instead of WiFi?
WiFi is convenient but has real limitations for monitoring dongles. Inverters are often installed in locations that are poorly served by the home router: garages, loft spaces, utility rooms behind thick masonry walls. 2.4 GHz WiFi loses signal through walls and is susceptible to interference from neighbouring networks, microwave ovens and other 2.4 GHz devices. A wired Ethernet connection eliminates all of this: it is unaffected by walls, distance within the cable run, or RF interference. A 30 m CAT5e run from the router to the inverter costs under £5 in materials and gives a rock-solid connection. If the monitoring system frequently drops offline and re-connects, switching from WiFi to Ethernet almost always resolves it.
Can I use this dongle with Home Assistant?
Yes. The Pocket WiFi+LAN’s Modbus TCP support enables direct local network integration with Home Assistant via the SolaX Modbus custom integration (available from HACS — Home Assistant Community Store). Modbus TCP allows Home Assistant to poll inverter registers directly on the local network without routing through the SolaX cloud, giving lower latency (sub-second) and offline operation. This is useful for dynamic battery control, EV charger management based on solar output, and integration with other home energy devices. You still need the Pocket WiFi+LAN installed for local Modbus access even without using SolaXCloud.
Is there a subscription fee for SolaXCloud monitoring?
No. SolaXCloud monitoring is free of charge for both homeowners and installers. There is no monthly or annual subscription fee for the standard monitoring and reporting features. Remote monitoring, historical data, performance reports, remote settings and OTA firmware updates are all included at no cost. Create a SolaXCloud account at solaxcloud.com or download the SolaXCloud app for iOS or Android, then register the dongle using the QR code or Registration Number during setup.
What happens to my monitoring data when the internet goes down?
The Pocket WiFi+LAN stores monitoring data locally on the dongle when the internet connection is unavailable. When connectivity is restored, the buffered data is uploaded to SolaXCloud automatically. This means your historical generation data will show a continuous record with no gaps for the outage period, rather than the zero-generation periods that appear with dongles that only transmit live data without local storage.
My inverter is in a garage — do I need the LAN version or will WiFi work?
It depends on the signal strength. If your router is in the house and the garage is a separate outbuilding, WiFi over 2.4 GHz through masonry walls is often very unreliable — expect frequent disconnections that result in gaps in your monitoring data. In this case, running a CAT5e or CAT6 Ethernet cable from your router to the inverter is strongly recommended. The Pocket WiFi+LAN is the right choice because it supports both: you can start with WiFi, and if it proves unstable, add the Ethernet cable without replacing the dongle. If WiFi signal is strong and stable in the garage, WiFi alone will work fine.
How do I set it up after installation?
1. Switch off the inverter and remove the DONGLE port cover. For WiFi only: insert the dongle and secure. For Ethernet: unscrew the cable entry end of the dongle, thread the Ethernet cable through, crimp an RJ45 connector, plug in and secure. 2. Restart the inverter. 3. Download the SolaXCloud app (iOS or Android) and create an account. 4. In the app, go to Account → WiFi Connection and follow the on-screen steps to register the dongle: scan the QR code or enter the Registration Number printed on the dongle. 5. For WiFi: connect your phone to the dongle’s temporary WiFi hotspot (named Wifi_SW…) and enter your home WiFi password in the app. For Ethernet: after plugging in the cable, the dongle connects automatically — no WiFi hotspot step required.
