FOX Inverter - Knowledge Hub

Reconnection Guide

Open your FOX app and follow the steps below to reconnect your datalogger.

• Open the FOX app.
• Click Devices at the bottom of the screen.
• Select Accessories and copy your datalogger serial number.
• Return to the Devices screen, tap Me in the bottom right corner, and select WLAN Configuration.

The app will now run a Bluetooth scan. It’s normal if the datalogger isn’t detected — wait until the scan finishes, then tap Input Manually in the top right.

• Paste your copied datalogger serial number.
• Press Connecting Network.
• Tap the picture in the centre to open your Wi-Fi settings.
• Disconnect your phone from your usual Wi-Fi network so the datalogger connection takes priority.
• Connect to the datalogger’s network — it will appear as W-XXXXXXX.
• If prompted for a password, enter mtmt2020.

If you can’t see the datalogger’s network, move closer to the inverter and try again.

• When asked to connect to a network without internet, select Yes.
• Go back to the app and select your home Wi-Fi network.
• Enter your Wi-Fi password, tap Next, then OK.

You can now reconnect your phone to your Wi-Fi.

• Return to the FOX app.
• On the Device page, confirm the datalogger shows as reconnected.
• Scroll down to refresh the page.

Please note: It can take up to one hour for data to reappear after a reconnection.

If it’s been longer than an hour and the issue continues, call Greenscape Energy on 01473 727727 for further assistance.

Common Alert Guide

From time to time, your system may display an alert. This is usually a notification of an event rather than a fault. Below are some of the most common alerts and how to resolve them.

‘BMS Charge Require No Reply’

This alert means the battery’s charge is very low, causing a temporary loss of communication between the battery management system and the inverter.

What to do:

• Contact Greenscape, who will liaise with FOX.
• FOX will perform a remote update to restore communication.
• Once the update is complete, you’ll be asked to carry out a system shutdown.
• During winter, you may be instructed to set a time charge to wake the batteries. The Technical Support team can handle this remotely if needed.
• After these steps, the alert should clear automatically.

‘Battery Over Voltage’

This alert indicates the battery management system has detected a higher-than-normal voltage within the battery.

What to do:

• Contact Greenscape, who will contact FOX.
• FOX will perform a remote update to stabilise voltage readings.
• Once the update has completed, monitor the system for one hour.
• The alert will clear automatically once normal operation resumes.

‘Communication Fault Between Manager and Meter’

This alert appears when communication between the meter and inverter has been lost — commonly caused by a power cut.

What to do:

• Check the fuseboard installed by Greenscape.
• If any fuses have tripped, push them back to the up position.
• Wait at least 30 minutes for the system to recognise the change.
• The alert should clear automatically once communication is restored.

‘No Utility’

This alert indicates that the system has lost grid connection — typically due to a power cut or following a system shutdown.

What to do:

• If you’ve recently performed a system shutdown, allow at least 1 hour for the alert to clear — this is normal.
• If no shutdown has been performed, check whether there has been a recent power cut.
• Inspect the fuseboard — if any fuses are tripped, push them back to the up position.
• Wait a minimum of 30 minutes for the system to recognise the change.
• Once power and grid connection are restored, the alert will clear automatically.

If any alerts persist after following the steps above, call Greenscape Energy on 01473 727727 for further assistance.

Shut Down / Start Up Procedure

You may need to power your system off or on for several reasons, such as:

• When electrical work is being carried out that requires the system to be turned off.
• When expanding your battery capacity.
• When resolving a fault on the system.

It’s crucial to follow the shutdown steps below in the exact order:

• If your system includes batteries, locate the power button and hold it down until all lights turn off.
• Turn the battery circuit breaker to the OFF position by rotating it anti-clockwise to the horizontal position.
• Isolate the DC side (solar panels) by switching the black/grey isolator to the OFF position.
• Isolate the AC side (batteries) by either turning the yellow/red isolator to the OFF position or flipping the Solar fuse in your fuseboard to the OFF position.

To turn the system back on, follow these steps in reverse order:

• Switch the AC side back ON.
• Switch the DC side back ON.
• Turn the batteries back ON.
• Press and hold the power button on the right side of the battery until the lights turn on.

Setting Up Charging Schedules for Load Shifting

If you’d like to optimise your system’s performance and reduce your energy bills, you can use the FOX Cloud scheduling tools to control when your batteries charge from the grid. This allows you to load shift — charging during cheaper rate periods and discharging during peak times — to make the most of your variable electricity tariffs.

To learn how load shifting can reduce costs and boost efficiency, visit: How Load Shifting Can Transform Your Home Energy Use.

There are two methods available for setting up your cloud schedules, depending on how simple or advanced your tariff is:

• Single Time Charge Setup — use this method if your tariff has a single off-peak charging period each day. This simple guide explains how to set one defined time for your system to charge from the grid automatically.
• Mode Scheduler Setup — choose this option if your tariff includes multiple variable unit rates throughout the day. The Mode Scheduler allows you to create intricate charging and discharging schedules that align with your energy provider’s changing rates.

If you’re unsure which method is best suited to your system or tariff, please call Greenscape Energy on 01473 727727 and our Technical Support team will be happy to advise.
