Solar Inverter Repairs Service

When your solar panels are generating power but your electricity bills remain high, the problem usually lies with the inverter. At HV Electrical Services, we specialise in solar inverter repairs for both domestic and commercial properties across the region. Our team understands that solar inverters are the hardest working part of your renewable energy setup. They convert direct current from your panels into alternating current that powers your property and feeds back to the grid. When this critical component fails, your entire solar investment stops delivering returns.

Solar inverters operate continuously during daylight hours, managing all the power conversion for your solar pv systems. This constant operation means inverters are the most common point of failure, accounting for over half of all solar repairs callouts we attend. The typical lifespan of a solar inverter is 10 to 15 years, meaning most setups will require at least one inverter repair or replacement during their lifetime.

We work with properties that installed solar panels years ago and those with brand new arrays. Regardless of your setup age, recognising faults early prevents costly energy losses. Faulty solar inverter problems can reduce overall performance by 20 to 50 percent, even if the solar panels themselves are working perfectly. This dramatic drop in efficiency impacts both domestic solar pv systems and larger commercial installations.

Solar inverters communicate problems through warning lights and error messages. These fault code displays provide vital clues about what has gone wrong, but professional solar pv inverter repair is usually required to fix issues safely. Common indicators include:

Red or amber lights that remain illuminated on the display signal something has triggered a protective shutdown. Your inverter might display error messages showing fault code numbers. These alphanumeric codes tell our engineers exactly where to start investigating. Some modern solar inverters send alerts directly to your phone through monitoring apps, whilst older models require physical inspection of the lights and display panel.

Performance drops are another clear sign that inverter repair is needed. You might notice your electricity bills creeping up despite good weather, or your fit meter showing lower generation than expected. Many property owners only discover inverter faults when they check their monitoring data and see the energy production has fallen significantly. Ignoring a faulty solar inverter can lead to higher long-term costs, as underperformance can quickly outweigh the pricing of professional repair work.

Solar inverters fail for several reasons, and understanding these helps property owners recognise when professional solar inverter repairs are needed. Software glitches affect modern solar inverters just like any computer device. These smart inverters require periodic updates to maintain efficient operation and communicate properly with the grid. Connection faults develop over time as terminals corrode or vibrate loose during the years of continuous operation.

Overheating occurs when ventilation becomes blocked or internal cooling components fail. This affects the efficiency of power conversion and can trigger protective shutdowns. Component degradation is natural in older models, particularly capacitors and circuit boards that wear out after years of service converting power from your panels.

Some inverter faults, like ground issues or insulation problems, can pose safety risks if left unresolved. That is why we always recommend professional inverter maintenance rather than attempting DIY solar repairs. Our NAPIT Domestic Installers and NICEIC Domestic Installers accreditations demonstrate we meet the highest safety standards for electrical work on solar pv installations.

Ignoring faults can lead to substantial losses. Consider a typical domestic solar installation generating four thousand kilowatt-hours annually. A faulty solar inverter reducing generation by 30 percent costs you around £250 to £400 in lost energy and higher electricity bills each year. Within two to three years, those losses exceed the cost of most solar repairs.

Repairing an inverter can restore up to 100 percent of lost energy production, immediately improving the efficiency of your solar investment. We have seen customers who delayed repairs for six months lose more money than the solar pv inverter repair would have cost. Your solar investment deserves protection, and prompt maintenance services ensure you receive the returns you planned for.

Commercial installations face even steeper losses. A business with a 50-kilowatt setup losing 40 percent efficient generation might sacrifice £3,000 to £5,000 annually. Our maintenance services for commercial installations focus on minimal disruption, ensuring your business continues operating normally whilst we restore your pv systems to full capacity.

From initial contact through to completion, we deliver efficient service that gets your panels generating again quickly. When you call HV Electrical Services for a free quote, we ask about your inverter symptoms, installation age, and configuration details. This helps us arrive prepared with the likely components and tools needed for your solar panel repair or inverter maintenance work.

Our engineer visits your property to perform a thorough evaluation. We examine warning lights, review error messages on the display, test electrical connections, and check the fault code history stored in the inverter memory. Modern solar inverters log multiple events, giving us vital clues about intermittent faults. We test voltage levels, measure current flow from your panels, inspect for physical damage to components, and verify your solar pv configuration matches your original installation specifications.

Once we identify the problem, we explain your options clearly regarding repair or inverter replacement. Many solar repairs take just a few hours to complete. Software updates and connection repairs happen quickly. Component replacements depend on parts availability, though we stock common items for leading brands. Throughout the process, we maintain clear communication so you understand exactly what maintenance work we are doing and why it benefits your solar system longevity.

After completing solar inverter repairs, we test the complete installation to verify it is generating at full capacity. We check the inverter communicates properly with your fit meter and feeds correctly to the grid. Before leaving, we provide guidance on monitoring your solar pv systems and recognising any future warning signs that might indicate developing faults.

We repair all common configurations found in solar pv installations. String inverters are the most widespread type, where one central unit manages the generation from all your solar panels. These powerful devices handle the full electricity production from your array. When string inverters develop faults, the entire installation stops generating power, making rapid inverter repair essential for both domestic and commercial installations.

Micro-inverters fit beneath individual panels, with each panel having its own small inverter converting power independently. These pv systems continue generating from unaffected panels even when one inverter develops a fault. Hybrid solar inverters integrate battery storage, managing both generation and stored energy. These complex units require specialist knowledge that our company possesses through our MCS Accredited Installers certification.

Each type presents different repair challenges. String inverters concentrate all the power conversion in one location, making them easier to access but potentially affecting your whole installation when faults occur. Micro-inverters require roof access to individual panels for solar panel repair work. Hybrid systems involve both the solar pv inverter and battery management components, requiring expertise across multiple technologies.

Solar panels and inverters come from many manufacturers. We service all following brands commonly found across UK properties. Solar Edge inverters are popular for their monitoring capabilities and power optimisers. These systems provide detailed performance data for each panel, making fault diagnosis more efficient. Fronius inverters from Austria have strong reputations for reliability and efficient operation across residential and commercial installations.

SMA inverters from Germany dominate commercial installations with their robust design and high power handling. GivEnergy and Growatt solar inverters increasingly appear in hybrid systems with battery storage capabilities. We also handle inverter repair and solar panel repair work for Solis, Enphase, Huawei, and numerous other manufacturers.

Our experience across manufacturers means we understand the specific characteristics and common faults affecting each brand. Many manufacturers require professional solar inverter repairs to keep warranties valid, and our MCS certification ensures your warranty remains protected. Parts availability varies by brand and model. Current production solar inverters usually have excellent parts supply through our company networks. Older models sometimes require refurbished inverters or compatible replacement components, which we source through our established supplier relationships.

Not every faulty solar inverter needs replacing. Many faults are repairable, particularly in newer units still within their expected lifespan. We recommend inverter replacement when the unit has reached 12 to 15 years old, when repair costs approach 50 percent of a new inverter, or when repeated faults suggest reliability issues are developing.

A new inverter costs between £800 and £2,500 depending on size and features. Inverter replacement makes financial sense for older models where multiple components are wearing out. Newer solar inverters often deliver better efficiency ratings than units from ten years ago, potentially increasing your energy generation from the same panels. Modern solar inverters also feature improved monitoring and smart capabilities that older models lack, helping you track performance more effectively.

Solar repair costs typically range from £200 to £600 for common faults. Software updates might cost just £150 to £200 for our maintenance services. Component replacements depend on the failed parts but usually stay below £500 including labour. We provide honest advice about whether inverter repair or inverter replacement offers better value for your particular situation and unique needs.

For installations still under warranty, solar repairs are often covered by the manufacturer. Our expertise with warranty claims helps secure the service your policy entitles you to. Even outside warranty periods, repaired or well-maintained solar inverters help extend the overall longevity of your installation by ensuring panels can operate at full capacity without faults limiting their generation.

Modern solar inverters are increasingly smart devices, meaning repairs often involve both electrical fixes and software updates. These sophisticated solar pv inverter units communicate with your generation meters, battery storage, and even your electricity supplier through the grid. They monitor grid conditions and adjust power flow to match demand and maintain efficient operation.

This complexity requires professional knowledge that DIY solar repairs cannot match. Safety is paramount when working on solar inverters. These units handle substantial power flows, with domestic solar inverters managing up to five kilowatts and commercial units potentially exceeding 50 kilowatts of generating capacity. Incorrect solar panel repair attempts can create fire risks, electrical hazards, or damage to other components in your solar pv systems.

Our engineers bring the right tools, knowledge, and safety equipment to every inverter repair job. We carry calibrated test equipment that accurately measures voltages and currents from your panels.

Large commercial installations might use multiple string inverters or powerful three-phase units managing substantial power flows from hundreds of panels. These pv systems feed considerable electricity back to the grid during peak generation periods. When faults occur, businesses lose both the direct power supply and the generation income from grid exports to the national grid.

We schedule commercial installation repairs to suit your business operations. Many companies prefer maintenance services during evenings or weekends to avoid disrupting trading hours.
