Solax Power Solar Inverter Faults and Repairs

Founded in 2010, Solax launched it's first solar inverters for the UK market in 2015. Most Solax Power inverters were provided with a 10 year manufacturer's warranty, so even if the initial installer is no longer trading, if there is found to be a fault with the inverter then Solax will cover the cost of a repair/replacement.

Solax Power Solar Inverter LED Indicators:

  • Green Light - The green LED indicates that the inverter is operating correctly.

  • Red Light - The red LED indicates that the inverter has detected a fault condition. A fault description will appear on the display.

  • Yellow Light - The yellow LED indicates that the inverter is in communication when blinking.

Solax Power Solar Inverter Faults and Warnings:

Some of the advice we give related to identifying, confirming and or resolving some of the faults detailed below, starts with safely shutting down and restarting the inverter and the solar PV system. This is something that nearly all solar PV systems installed in the UK would have been designed to be carried out safely by the solar PV system owner. However, paperwork, schematics and manuals are not always clear or available, so if you have any concerns about how to do this, we will always be pleased to talk you through the process over the telephone at no charge.

How to Restart a Solax Power Solar Inverter:

Leave everything near the supply meters turned on. At the inverter there will be an AC isolator, this is used to isolate the mains/grid supply from the inverter and to prevent the inverter from feeding solar power into the electrical system. Switch the AC isolator 'off', if the inverter is running correctly you will hear a clunk inside the machine and after a while a 'no-grid', 'missing grid' warning or similar on the LCD display.

Solar PV System Restart

Near to and or built into the solar inverter will be a method of isolating the solar (DC) supply from the inverter. Often these are black and grey and will be labelled 'DC isolator' or similar. There might be two or more of these if the system is fed by multiple strings. If there isn't a seperate DC isolation device, there will be a way to isolate the DC supply built-in to the inverter itself (often a rotary style switch underneath), turn this 'off'.

When all of the lights on the solar inverter have gone out, reintroduce the AC/mains supply by turning the AC isolator 'on'. Introduce the DC supply by turning all DC isolators 'on'.

This will restart the solar inverter, on the display it might show you progress during it's startup procedure. During startup is when the solar inverter carries out all of the tests needed before being able to connect the solar supply to the electrical system. If errors are found during testing they will be displayed on the screen or an indication light might come on. Make a note of any warning messages, warning lights and fault codes.

If the restart is succesful a green light will come on, sometimes flashing at first but once connected to the mains/AC supply remaining permenantly on. The LCD display will show how much power the solar PV system is generating. The solar PV system can be verified as working at the solar generation / Feed in Tariff (FIT) meter which will count on the display, the red light will pulse as it counts.

Solax Power Solar Inverter: No lights, No Display

Solax Power solar inverters are powered by the solar panels (the DC supply) and will startup at sunrise each day and shutdown at night. If you find the inverter with no lights or display working during the day, there is either a problem with the solar panels or with the inverter. Follow the shutdown and restart procedure outlined above and if the problem persists Contact us to discuss the next steps.

Solar Inverter Recycling: - Recycling Solax Power Inverters

Solax Power inverters contain valuable materials such as copper and aluminium, these materials are in high demand and recycling them is significantly less energy intensive than extracting them from ore.

If you find yourself with a damaged or faulty Solax Power inverter, we will be pleased to help you recycle it.

Solar PV Inverter Replacement

If you have a faulty inverter, we offer an efficient, value for money, hassle free inverter replacement service. We offer good advice and install quality equipment with comprehensive warranty and support options. We will test the rest of the system as part of the service, take care of all hardware deliveries, record your new unit's serial number and confirm the warranty details with the manufacturer.

Our engineers work cleanly and will dispose of any unwanted boxes, faulty equipment and packaging.

Many modern inverters can now use wireless home networks to transmit solar generation data to PCs, tablets and smartphones, so if you would like something like this, let us know and we will be happy to set it up as part of the installation.

Mains/Grid Isolation and Surge Protection

Mains/AC Surge Protection Solar PV Systems

A whole house surge protector is installed to provide protection from transient overvoltages originating from the mains/grid. A whole house surge protector is installed directly inline and as close as possible to the incoming mains/grid supply meter, this allows for surge protection for all circuits and equipment including solar inverters, routers, stereos and other sensitive electrical equipment within the network. The addition of a 100Amp lockable isolator also allows for safe and convenient isolation of all electrical equipment within the network including consumer units, solar inverters, battery storage units and EV chargers from the mains/grid in one place.

Surge protectors are in compliance with the recently updated 18th edition amendment 2 of BS7671.

What Our Customers Say:

"Our inverter failed and as our installer had gone out of business did not know what to do. Contacted Glen who was brilliant. Came out checked the failure dealt with the manufacturer and all aspects of the warranty claim.New inverter received under warranty and Glen came out and fitted the new one straightaway. Superb service from a very professional and helpful person. Highly recommend this company." Martin Brailey, Wokingham
