⚙️ Solar & Battery System – Quick Fixes & Troubleshooting

If your app has stopped updating, or your system seems to be offline, don’t worry — most issues are simple to fix.
Use the guide below before contacting Solar Voltaics.

🔹 App Not Showing Data or Appears Offline

Likely cause: Lost Wi-Fi connection.
Steps to fix:

1. Check your home Wi-Fi is working (test with your phone or another device).

2. Check your inverter or battery has power and the indicator lights are on.

3. If you’ve recently changed your router or internet provider, reconnect your system to the new network (see Wi-Fi Reconnect section below).

4. Wait 15–30 minutes for data to reappear in your monitoring app.

💡 Tip: Your solar system continues to work even if the app is offline — generation data will upload once reconnected.

🔹 Inverter or Battery Says “No Communication”

Likely cause: Temporary connection or firmware issue.
Steps to fix:

1. Turn off both PV and AC isolators next to the inverter.

2. Wait 60 seconds.

3. Turn the isolators back on in the same order.

4. Check that the Wi-Fi dongle/data stick lights are illuminated.

5. If the issue remains, contact the manufacturer’s support (see contact list below).

🔹 Battery Not Charging or Discharging

Likely cause: System mode or weather conditions.
Steps to fix:

1. Check inverter screen shows Normal / Charging / Discharging.

2. Confirm there is daylight and solar generation available.

3. Ensure your system isn’t in Backup Mode or Eco Mode (varies by brand).

4. After a power cut, give the system up to 30 minutes to resynchronise.

🔹 App Login or Password Not Working

1. Double-check your email and password.

2. Use the “Forgot Password” link in your app or manufacturer portal.

3. If your account was set up by Solar Voltaics, some manufacturers (e.g. GivEnergy, FoxESS) may require re-activation — contact their support line.

🔹 EV Charger Not Responding

1. Check the consumer-unit breaker or RCBO feeding the charger is switched on.

2. Verify the Wi-Fi or Ethernet connection.

3. Unplug the cable, wait 30 seconds, then reconnect.

4. If you’ve changed Wi-Fi, reconnect the charger to the new network.

🔹 No Power or Blank Inverter Display

1. Check your home has electricity (not a grid power cut).

2. Ensure AC and DC isolators next to the inverter are in the ON position.

3. If still blank, contact Solar Voltaics for assistance.
