Solar Power System Repairs

Problems with a solar PV system? Solar panels not working? Fault code on a solar inverter? Faulty Solar Generation Meter? We can help.

Established in May 2007, we are one of the longest serving and most experienced renewable energy companies around, we've carried out all sorts of repairs involving most types and size of solar PV system, so if you have a fault with a solar PV system, contact us and we will be pleased to help get the system back up and running.

Mains/Grid Isolation and Surge Protection

A whole house surge protector is installed to provide additional 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.

Solar Roof Repairs

A poorly designed and installed solar PV system can cause terrible damage to roofs, which over time can allow moisture to enter and further damage the structure of buildings. Cracked tiles, poor flashing work, damaged underlay, battens and rafters, use of incorrect fixings, poor installation methods, there's a lot that can and has gone wrong when installing solar panels onto roofs.

If you have a problem with a roof where solar panels have been installed we can help.

Solar Generation Meter Replacement

Occasionally solar PV generation / Feed in Tariff (FIT) meters fail and need to be replaced. The good news is that replacing them is a straightforward process but to avoid FIT payment delays and complications it's important to let the FIT provider know that the solar generation meter has been changed.

Here we outline the process and also some diagnostics that you can carry out to confirm that the fault is with the solar generation meter and not a symptom of a fault elsewhere with the system.

The maximum DC input voltage per tracker is 600V, with each tracker's operating range up to 550V DC, so these won't be suitable for very high voltage DC strings. They will however be a good replacement solar inverter for most solar PV systems rated up to 4kW DC / 3.68kW AC. The dual MPPT Series 6 ranges from 2.5kw to 8kW on a single phase.

Solis solar inverters are well built and have a solid feel to them, the chassis is well sealed, the giant heatsink on the back constitutes nearly half the volume of the inverter and keeps the components inside the unit cool. Although it's always good to try and keep solar PV inverters protected, these inverters are IP rated and able to be mounted outside.

The functions available at the solar inverter using the buttons and the LCD screen are basic for most of the time although all of the installation settings that might be needed are available in the advanced settings.

Pretty basic in comparison to some other manufacturer's offerings but when it comes to solar PV inverters in terms of reliability and servicing often basic is just what you need.

If what you are looking for is a solid, reliable grid connected solar inverter, at a good price, that converts DC to AC efficiently and keeps an accurate log as it does so, then in our opinion a Solis Series 6 or Mini Series 6 solar inverter would be a good choice.

Solar PV Generation / Feed in Tariff (FIT) Meters

Single phase, 100A, Solar PV Generation / Solar Feed in Tariff (FIT) Meters

• Large easy to read display
• Internal battery allows meter data to be accessed when the grid/mains power supply is off
• Records invoicing data for 12 months, records generation data for 6 months
• Auto troubleshooting: Cover open, low battery warning, clock error
• Lockout security kit, optical port and meter collars
• MID approved / OFGEM approved for use with Solar PV Feed in Tariffs (FITs)

Button scrolls through: Date, Time, Total Generation (kWh), Maximum Generation (kW) and when this was recorded.

New Article: ... BSI - PAS 63100:2024 - Protection Against Fire of Battery Energy Storage Systems for use in dwellings

This Publically Available Specification (PAS) from the British Standards Institution (BSI) was sponsored by The Department for Energy Security and Net Zero. Although not a British Standard, this guidance was developed in response to an urgent demand for clarity as to good practice across the industry including product, service and process standards.

New Article: ... Ground Faults, Isolation (ISO) Faults, RISO Low Faults and Insulation Resistance Faults with Solar PV Systems

After a number of years exposed to wind, rain, snow, ice and sometimes animals; solar panel systems can start to develop faults. The most common faults we find related to exposure are ground faults, isolation (ISO) faults, RISO low faults and insulation resistance faults. In this article we take a look at what these faults are, the possible causes and what steps are taken to identify and resolve them.

New Article: ... How to provide backup power to a house using a portable generator

In this article we show you how to provide backup power to a home using a portable diesel, petrol or LPG backup generator. We look at changeover switches, the importance of earthing, backup generator loadings, how to isolate non essential loads. We ask where to locate the backup generator when it's in operation, how best to safely isolate the grid/mains power supply and switch to a backup generator supply, including the procedures involved in backup generator start up.

New Article: ... Surge Protection for UK Solar PV Systems

Recent changes to the BS7671 UK Wiring Regulations 18th Edition in the form of amendment 2 have introduced requirements and considerations for surge protection on both the AC and DC side of a solar PV System. In this article we take a look at surge protection, particularly in the context of the updated UK wiring regulations and how surge protection could best be incorporated into new and existing solar PV systems installed in the UK

Updated: ... Solax Hybrid Inverter Faults and Repairs

Founded in 2010, Solax launched it's first solar inverters for the UK market in 2015. Most Solax Power hybrid 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 solar inverter then Solax will cover the cost of a repair/replacement. Popular early UK models of Solax hybrid inverters include the SK-SU3000, SK-SU-3700 and the SK-SU5000.

Updated: ... ABB / Power One Aurora Inverter Faults and Repairs

As a result of their popularity we have become very familiar with repairing, servicing and diagnosing faults with Power One solar inverters. Power One Aurora solar inverters, both single phase (Uno) and three phase (Trio) have an LCD display on the front of the chassis. Identifying error codes shown on the display (assuming the display is working) is usually the best place to start in diagnosing the fault and getting systems using Power One solar inverters up and running again.
