Troubleshooting Guide

If you have an issue with your Solar PV, please carry out the following checks. 9 out of 10 customer issues can be resolved quickly online to get your system back up and running in the shortest time possible.

Solar Not Generating

Check the Generation Meter

Fuse Gen Meters

Is the light flashing red?

The system is generating electricity but may not be working to its full potential. This could be due to degraded panels, the optimiser (if fitted), the wiring, or a fault on the inverter.

Is the light solid red?

A solid red light indicates the system has power but it’s not generating and this could be a fault with the inverter.

No light on at all? (display blank)

Check the fuses in the consumer unit

If the system has no power and the light is not on then please check your consumer unit (fuse box) to ensure that all fuses are in the up (on) position. It could be that one of the fuses have tripped and its a simple matter of resetting the fuse. (Note: it can take up to 5 minutes for the system to reset)

Please take note of the generation meter reading

lights

Is the light flashing red?

If you have a consistently flashing red light, then your system is working correctly and this flashing light is showing that your system is generating as it should be.

Is the light solid red?

If you have a solid red light this usually means that you have a fault and your system is not generating as it should be. The good news is that this can usually be fixed without requiring a engineer visit.

Do you have a separate fuse box for the solar? Check to make sure that all the fuses are in the ‘on’ position.

Is your inverter showing any error messages? Please take note of the error message and restart your inverter.

Restart Your Inverter

Most faults can be reset by simply restarting your inverter. To do this…

Turn off the Black DC Isolator Switches (there will be one for each string)

Wait a few seconds then turn the Red AC Isolator off.

Wait 30 seconds, then turn them back on in reverse order. (Red AC Isolator, then Black DC Isolator)

Wait a few minutes and see if this rectifies the issue (If you have a voltage optimiser, restarting the inverter will take up to 15 minutes).

If this resolves the error code, please keep a log of your generation meter readings for the next 7 days, so we’re able to keep track of your generation.

App Issues

The main cause of an app not working or showing a fault is down to WIFI or internet connectivity. If you’ve recently had a power cut or changed your internet/broadband password, you’ll need to reinstate the app for WIFI access.

WiFi Setup

Please note you can only setup the app on one device

Ensure the wifi dongle (a rectangular USB dongle with green lights) is plugged into the underside of your LuxPower unit.

Open your mobile phone or other smart device and search for wifi connections. You will find a wifi connection whose name matches the serial number on the dongle. Connect to this. Your phone may read ‘no internet connection’ – this is fine, and you should proceed with the connection anyway.

Open your internet browser e.g. Chrome, safari etc.

Ensuring that you are connected to the dongle as a wifi connection, as in the previous steps: In the browser bar (NOT the google search bar) enter the address ’10.10.10.1’ minus the quotations.

The address will ask you for your sign in id. This is as follows: Username ‘admin’, password ‘admin’.

The site it takes you to may be in Cantonese or Mandarin. Just go to the top, there should be button that reads ‘English’. Press this.

On the list on the left, select ‘station mode setting

At the top you will see ‘SSID’, hit scan to the right of this. This will bring up a list of nearby wifi connections. Select your new router from the list, and press okay.

The screen will go back to the previous page, where you need to enter your new router’s password and hit ‘save’.

The system will ask if you want to reboot the module. Press yes.

Then it is just a case of waiting for the module to restart. If all instructions have been followed correctly, after a few minutes all three lights on the dongle will go green, and within ten minutes the battery will reappear on the app.

Import/Export Explanation

Battery Storage systems work on ‘cause and effect’, meaning that the battery system needs to determine changes to the installation environment – load, PV generation, grid frequencies etc. – to then respond to those changes. Therefore, although extremely fast, the Lux system cannot be 100% accurate.

The monitoring is a tool to look back at the performance of your system. You can see current data, but it is NOT REAL TIME DATA. It is just a snapshot of information which refreshes every 3 minutes. So, you must allow your system to refresh and use the data and graphs to analyse performance.

Do not think that because the data looks unusual there is any problem, you need to allow it to refresh, here is why:

As loads in the property increase or decrease the electrical supply from the grid is instant. The Lux system will continually monitor and adjust to any load requirements within 3 seconds.

The monitoring data shown on the monitoring platform is a snapshot (split second of data) taken every 3 minutes. The accumulation of this data is shown on the internal Data section of the system. The snapshot data remains on the monitoring display until the next snapshot is taken and the monitoring refreshes.

Therefore, if that snapshot is taken as loads are changing the split-second data will show for 3 minutes while the system continues to adjust and react within seconds.

Lux Handheld
Lux Macbook

Import/Export Explanation Power to Grid

For Example, the load is 300w, and the battery is discharging 300w to supply the load, then the load requirement changes to 170w, then the excess energy of 130w will momentarily feed to the grid. If the snapshot happens at that moment, it will show 130w export on the monitoring for 3 minutes, although the system will have then adjusted within seconds.

The inverter detects the load change through the external CT clamps (with a 500-millisecond reaction time) which continues to feed information to the Lux unit, which will therefore react accordingly.

The opposite is therefore also true, so if the load is 170w and increases to 300w, there will be a moment where there is 130w coming from the grid until the 2 second reaction allows the battery side to discharge.

The speed and reaction time of the Lux units is tested and certified. The Monitoring platform is provided free of charge as a portal to the systems overall performance, but is not live, and therefore must be used and interpreted accordingly.

Lux App Settings

Your Lux App can alert you to any faults with your system. Your settings for charging and discharging your batteries can also be changed.

Charge Settings

To change your settings go to ‘Charge Setting’ and set AC charge enable to ‘enabled’, then set two times to start and finish, this will set the battery to charge from the grid. 

Before changing any settings please make sure you press ‘read all’ and allow the data to fill.

Notifications & Alerts

To change your settings go to ‘Charge Setting’ and set AC charge enable to ‘enabled’, then set two times to start and finish, this will set the battery to charge from the grid. 

Before changing any settings please make sure you press ‘read all’ and allow the data to fill.

Notice Error Message Faults

Communication failure with battery – Try restarting battery, if this doesn’t work, consult battery manual and ensure cable connections and DIP switches are correct


AC Voltage out of range – voltage coming into the property is too high. We cannot correct this. Will need to speak to their energy provider


Battery voltage low – The battery is low on charge and is just alerting you. It should recharge when it next is able to from excess sun or set AC charge times


No AC Connection – The battery has lost connection to the fuse board. Check all fuses, especially the PV and battery fuses, are in the on position.


Battery Open – this means that the battery is stuck ‘on’ when the inverter has restarted. Restarting the whole setup, including the inverter, should remedy this.

Low Feed-In-Tariff

If you’ve noticed that your FIT Readings or FIT Payments are lower than normal, this could be due to a number of reasons.

In a nut shell, if your Solar PV hasn’t been working or you’ve had a fault then you will not be producing your usual amount of energy. This will result in low feed-in-payments from your energy supplier.

Power cuts at your property will affect your energy generation and in return affect your FIT payments. Your Solar PV system will have been generating less energy due to these power cuts.

No electricity, means no power to your inverter. No power to your inverter means no energy generated from your Solar PV system.

Dirty Solar Panels can massively reduce your generation. If you have a build up of moss, leaves, dirt or bird droppings, try giving your panels a quick hose down. Alternatively seek a professional to help clean your Solar PV array.

Have you checked with your energy provider that they haven’t changed or amended your Feed-In-Tariff terms or payments?

If your iBoost+ was installed by ourselves then we’re able to provide full support for this product. Don’t worry if we didn’t, as we can still provide help and advice.

If you’re seeing a ‘Lost Connection to Sender‘ error message, this usually means that the batteries in the iBoost+ Buddy need replacing. Replace the batteries and see if this resolves your issue.

Pest Issues

Pigeons love to make nests under solar panels and can cause real damage to the cabling and MC4 connectors. As they fly in and out of their nest their droppings can also cover the panels reducing the efficiency and affect your total energy generation.

We do not offer a pest removal service, so please seek professional help in order remove the nest.

What can go wrong?

Inverter

Inverters typically last for between 5 to 7 years, and can be subject to voltage spikes that may cause them to overheat, shortening their lifespan. The cost of a replacing inverter can be between £800 and £1500

Generation Meter

The generation meter measures the total amount of energy that your system produces. There are a few reasons why your generation meter may fail but the end result is that your payments will be affected until it is repaired or replaced.

MC4 Connectors

The MC4 connectors used to connect the panels on your roof can harden over time and lose their conductivity, which can reduce voltage and affect the performance of your system. A reduction in generation could be a result of faulty MC4 connectors which may need replacing.

Panels

Your solar panels are the heart of your system. Because they’re exposed to extreme temperatures, they may deteriorate over time, producing less electricity and ultimately failing. The cost of replacing a panel can be high especially if scaffolding is required to carry out the repair.

A fault on your Solar PV System, whatever the cause, may not be noticeable to you right away, but will have a huge impact on your electricity bill and your feed-in-tariff payments. Regular checks and preventative maintenance can help ensure that you’re getting the very best from your solar panels, safe in the knowledge that, should a problem arise, we’re on hand to take care of the issues for you.
