How We Can Help
Here at spectra solar not only do we supply and install new solar pv and battery storage systems we also cater for existing installs.
Whether it’s a faulty inverter, faulty panels or something else we can help.
Many older style inverters came with a 5 year warranty, most of which have well surpassed that time now and the chance of the original installer still being in business is slim as most have closed their doors after the Feed-in-Tariff came to an end.
Repairing an old style inverter usually isn’t cost effective as it will only have 12 months warranty on the repair. Although this is the cheaper option it makes more sense to replace with a newer, more efficient design that will come with a 10 years warranty.
Before we dive into common faults and issues with different inverter manufacturers we have created below a simple flowchart help guide of common faults that can be rectified easily.
Still not working? Don’t worry, below we have listed of some of the most commonly fitted inverters that have been installed during the last ten years and the most common faults that come with them.
If you would like to discuss your fault please get in touch with by us either

Really happy with the post installation backup Jonathan and everybody at Spectra have given me. Jonathan also patiently explained all the pros and cons before installation and helped with the form filling with my energy provider.

Had my solar installed on the 18th of June. The lad Jonny I think his name was and the other lad did an excellent job of installing my panels and giving me information on the install process. The electrician Liam was great. Talked through the best way he was going to do the work and if I was happy with the way to install and connect the battery. Customer service aftercare have been great also. Very correspondent to emails and phone calls and always happy to help and give you information. Would strongly recommend spectra solar if you want a solar company.

So helpful and friendly! We have a system fitted by a different installer who are not trading anymore. When we had an issue with our Dongle we were at our wits end but a member of the team ( John I think) talked us through what to do- and it worked!! Saved us a call out fee and also saved our sanity. Top notch service from a company is to be praised! Won’t hesitate to use them if we need anymore solar related products!!

from first contact with Jonathan to discuss my options of upgrading my current solar system with complementary batteries to the install today from Liam, I can't fault them!!
Jonathan is always available to discuss and help with any questions or queries ad Liam and his buddy did a great job installing them today, left the area clean and tidy and explained the work he'd done.
Wouldn't hesitate in recommending Spectra Solar to anyone looking to help reduce your energy costs. 👏

We read reviews of quite a few companies before settling on Spectra. Many of them were 5 star and I've no reason to think they wouldn't have also been excellent so choosing was hard, but in the end we went with the one our neighbour had used. Have to say we can't fault them - the end to end process was handled really well. Communication has been excellent and the installation and follow up support has been everything we could have asked for. So I'd have no hesitation in recommending them to anyone struggling to choose. The price was also very competitive btw. Thanks guys

Shopped around for solar panel and battery installation. Decided on Spectra due to being a Which approved trader and using there own installation team. The price was not far off the cheapest as well. Also no pressure selling.
Roofing lads Brett and Brook arrived just after 8am and the electrician Liam about 9 who went through everything with me.
The whole team were a credit to the company. Everything was left clean and tidy after installation and a full explanation of how the system app worked.
Post and pre install comms from Kurt was and is still excellent. No issues to report. All documents sent through straight after payment.
Really pleased with whole process.
14 panels
Hanchu battery and invertor. All neat and tidy.

To save you reading the rest - I'll sum it up in one word - Impressive!
From inital contact there's no hard sell, no pressure, but plenty of advice. Having contemplated solar for a few months, I'd done plenty of research. Being local to their offices, the wife and I arranged to pop in to their showroom.
Again no pressure, no hard sell, but very knowledgeable, backing up I'd gleaned from my research.
Mike turned up to conduct the survey as arranged, I wanted to be clear on what to expect and if there were any issues, and Mike made suggestions on how to install the equipment in the garage without damaging the pre-fab concrete.
We agreed on the trench location between the house and garage to prevent damage to the new driveway - Important as the scaffolders errected their scaffold right over the area, luckily I was at home when they came to errect it and they managed to position the two legs so not to be in the way.
Installation day, the lads rocked up just after 8am on a frosty January morning, Tea, Coffee & biscuits were welcomed by them, they simply just got on with it. I was sceptical they'd get it done in the day, but the roofing team were done by mid afternoon, leaving the electricians to connect and commission the system. That was all done around 5pm.
The installation in the garage with Uni-Strut is tidy, they routed the DC cables through the soffit, from the loft space - I was expecting a hole through the wall. The internal consumer unit is tidy, and there's been no issues since the install.
I can't wait for the sunnier weather, as despite the rain & fog recently the system's already impressed me with it's generation quite offten the base load is solely from PV.

I would highly recommend Spectra Solar Ltd for the installation of Solar PV system on your residence.
Right from the start i noticed how excellent Mike was at communication. It is clear that he is an experts in this field, but they took the time on numerous occasions to talk me through the various options and tweak to match my needs or requests. All of this was done in language and terminology that I could understand. Once I was happy for the order to go ahead, Spectra Solar Ltd team delivered on the promised date for the setup of my installation of system.
On the day the team consisted of Jordan, Brett and Wayne. I was very much impressed on how they performed their task in a professional, neat yet thorough manner and were very much approachable and considerate of my needs. I can’t fault their workmanship (top notch). My system consists of 11 solar panels, 7.2kwh battery and 3.6 inverter. To my surprise the job only lasted a day.
Another important factor for me was that Spectra Solar Ltd ask for no upfront payments and the final payment could be paid on card, which was a positive for me.
Overall a super experience 😁
Thank you Mike, Emma, Jordan, Brett and Wayne.

I highly recommend this company. Too often we are let down by merchants making appointments and not appearing. Spectra fulfilled all of their commitments leading to our installation recently. The weather was awful on the due day but fitters arrived on time followed by electricians. All were courteous, respectful and helpful. As promised the installation was completed in one day - not easy on a dark wet day in December - and full instructions were given to download the ubiquitous 'App'. The fitters finally departed in the dark having cleaned up behind themselves. I am delighted with the work which is generating already.
