One of the most common faults relates to the Solar PV Inverter, as this is the hardest working part of any solar system. GOS can repair or replace your inverter with minimum fuss, ensuring that your system is optimally performing.


Inverters are much more technically sophisticated than solar panels and are not something the average person should touch, for inverter maintenance you should always choose a qualified engineer such as the team at GOS Heating. The electrical components and high voltage elements make this too dangerous for people without certifications.Inverters work in a similar way to a fan in a computer, inviting dust into electrical components, you might ask what can dirt do to an inverter? If it’s got the right particles, it can create new conduction pathways on the circuit boards, which in extreme cases can lead to circuit failure. Humidity is also another problem for your inverter as it can invite more corrosion risk for electrical terminals and connections

We're very satisfied with the boiler service today. Barney arrived on time and was friendly and polite — discussing the condition of the boiler and our options. The job was completed in good time with everything left clean and tidy. Thank you.

Absolutely fantastic service. Thanks Sam.
Called GOS after the previous plumber couldn't fix a problem with the heating. The lady on the phone was really helpful and found an engineer just finishing up and sent him straight over. Chris was excellent, quickly diagnosing and explaining the problem. He was spot on and had it fixed within minutes. Really nice guy, and refreshing to meet someone with a solid understanding of heating systems and excellent customer service. Will definitely be calling GOS first next time.

Chris and the team at GOS have looked after our boiler since fitting it 12 years ago. Very friendly and professional service. Have recommended this company to many of our friends.
GOS Heating replaced a very old back boiler with a modern Vaillant combi system. The customer is my mother who is almost 91 years old. A couple of issues arose, one relating to the shower with the change from gravity system to pressurised. The other was a non installation related but coincidental electrical promlem. The GOS engineers were patient and tolerant with my elderly mother and saw the job through to a satisfactory conclusion. I have no hesitation in recommending GOS as a reputable and trustworthy company.
Our landlord started using gos a few years ago and they have been great from the start. Today we had a new boiler installed by Sam and Richard it was a big job. The guys were absolutely great friendly and worked really hard to get the job done. Can't recommend this company enough brilliant from start to finish. Thank you
Rang on Friday to request a service and repair, had someone out by Wednesday. Chris came to do our service and within an hour he had completed that and priced up the parts for our repair which should be done in a couple of days. Really happy with the service and Chris was lovely too.
Completed boiler service very efficiently, friendly and helpful
The workmen were polite and helpful. They arrived on time and finished on schedule leaving the place spotless. The follow up was useful too.

Very good efficient service. Explained issues and fixed both boiler issues within an hour
In Autumn 2023 I moved into a property with a quirky heating system that needed urgent replacement as the temperatures were falling. I contacted GOS and they ripped out the old heaters and replaced everything with a top-of-the-range Gas Combi and rads. This has worked efficiently. I have just had the first twelve monthly service; all good. As well as high quality products I liked the fact that the personnel are pleasant and punctual. Recommended.
Nat was very helpful, pleasant and nothing was too much trouble. Thanks!
Friendly Engineer who did an efficient job. Will use again.
Excellent service received. Engineer arrived before time and fixed the problem with my boiler straight away
Excellent & dependable in EVERY WAY!!
Great service, always use as professional and totally reliable

Microinverters are also becoming a popular choice for residential and commercial installations. Like power optimisers, microinverters are module-level electronics so one is installed on each panel. Microinverters convert DC power to AC right at the panel and so don’t require a string inverter.
Because of the panel-level conversion, if one or more panels are shaded or are performing on a lower level than the others, the performance of the remaining panels won’t be in any jeopardy. Microinverters also monitor the performance of each individual panel, while string inverters show the performance of each string. This makes microinverters good for installations with shading issues or with panels on multiple planes facing various directions. Systems with microinverters can be more efficient, but these often cost more than string inverters.
Battery Based Inverters are bidirectional in nature and include both a battery charger and inverter. Battery-based inverter/chargers may be grid-interactive, standalone grid-tied or off-grid, depending on their UL rating and design. The primary benefit of inverter/chargers is that they provide for continuous operation of critical loads irrespective of the presence or condition of the grid.
Battery based inverter/charger manages energy between the array and the grid while keeping the batteries charged. They monitor battery status and regulate how the batteries are charged.
