Solar Tepairs

Solar Power System Repairs

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/AC Surge Protection Solar PV Systems

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 PV Inverter Replacements

If you have a faulty inverter, we offer an efficient, value for money, hassle free solar 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 the 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.

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.

DC Surge Protection Solar PV Systems

Solar PV Surge Protection (DC Surge Protection)

DC surge protection devices (SPDs) are installed between the solar panels and the solar inverter to protect both the solar inverter and the downstream electrical equipment from transient overvoltages of an atmospheric origin impacting the electrical system via the DC side of the system / the solar panels.

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

Solar Generation Meter Replacement ' Feed in Tariff (FIT) Meter Replacement

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 elswhere with the system.

Solis Series 6 and Mini Series 6 Inverters

The Solis Series 6 and Mini Series 6 inverters are our go-to solar inverters when asked to carry out a cost effective solar inverter replacement or to supply a quality solar inverter for a new system at a competitive price.

All Solis Series 6 solar inverters come with 2 x MPPT trackers, if you only need the 1 tracker then a Solis Mini Series 6 is a little smaller but also a little cheaper and just as good. Both unit types have easy to use buttons, an LCD screen and a communications port for wireless @2.4Ghz, wired LAN or GPRS. The three lights above the display indicate the status of the inverter and are clear to see from a distance.

Solis Series 6 Dual MPPT Solar Inverter

Solis Mini Series 6 Single MPPT Solar Inverter

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 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 units 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 inverter using the buttons and the 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.

Warranty extensions for Solis inverters are good value and can be upgraded from 5 to 10 years. Warranty extensions can be ordered with the new inverter or anytime up to a year after installation.

Solar PV Generation Meter

Solar PV Generation / Feed in Tariff (FIT) Meters

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

In this article we show you how to power a home using a portable diesel, petrol or LPG generator. We look at changeover switches, the importance of earthing, generator loadings, how to isolate non essential loads. We ask where to locate the generator when it's in operation, how best to safely isolate the mains supply and switch to a generator supply, including the procedures involved in 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 inverter then Solax will cover the cost of a repair/replacement. Popular early UK models of Solax hybrid invertes 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 Inverters. Power One Aurora 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 inverters up and running again.

Updated: ... Growatt MTL-S Series Inverter Faults and Repairs

Established in 2011 in Shenzen, China, Growatt launched it's first products for the UK market in 2013. Growatt is now one of the top 4 solar inverter manufacturers in the world. The MTL-S Series inverters were widely installed in the UK from 2013 through to 2019.

Updated: ... Sofar Solar Mass Energy Storage Inverter Faults and Repairs

Established in 2013 Sofar Solar launched the ME3000SP Energy Storage Inverter in the UK in 2015. The ME3000SP proved to be a very succesful add on for new systems but proved to be particularly popular with those looking to add energy storage to existing solar PV systems.

What Our Customers Say:

"Can't recommend In Balance Energy and Glen enough. I had a fault in a solar tile that needed tracking down. Other companies did not want to know as too much hassle. Glen saw it as a challenge and was all over it. Problem fixed and full power restored. Well done and thanks." Paul Rodwell, Wallingford
