How to Install the Inverterzone Solar WiFi Dongle
Setting up your Inverterzone Solar WiFi Dongle takes about 10 minutes. Follow the steps below to get real-time solar, battery, and grid monitoring on your phone.
Step 1: Locate the RS232 / RJ45 Port
Find the RS232 communication port on your inverter — usually labeled COM, RS232, or PC. This is separate from any Ethernet/LAN port your inverter may have. Check our Compatibility List if you're unsure which port your model uses.
Step 2: Plug In the Dongle
Insert the WiFi Dongle directly into the RS232 port. No external power source is needed — it draws power from the inverter itself. If your inverter uses a DB9-style RS232 port, use the correct RS232-to-RJ45 adapter cable (available separately in our store).
Step 3: Power Cycle Your Inverter
Turn the inverter off and back on after connecting the dongle. This lets the inverter recognize the new serial device.
Step 4: Download the App & Connect to WiFi
- Download the Inverterzone app for Android or iOS
- Create an account or log in
- Tap Add Device and scan the QR code on the dongle, or enter its serial number manually
- Select your home WiFi network (2.4GHz only — most dongles don't support 5GHz) and enter your password
Step 5: Confirm the Connection
Once connected, check the app for live Solar, Battery, and Grid data. If you see "device not registered," give it a few hours to sync, or reach out to us on WhatsApp and we'll verify it from our side.
Troubleshooting
- No data showing: Double-check you're plugged into the RS232/COM port, not a different port.
- Won't connect to WiFi: Confirm your network is 2.4GHz, not 5GHz-only.
- "Device not registered": This usually resolves within a day. Message us on WhatsApp if it persists.
- Inverter not listed in the app: Contact us on WhatsApp with your inverter brand and model — we support 239+ models across 38+ brands and can confirm compatibility.
