Dutch company Mastervolt, founded in 1991, launched it's first photovoltaic inverter in 1993. Mastervolt are now part of power conversion and management equipment giants Power Products LLC. Mastervolt Sunmaster and the smaller Soladin ranges of inverters were widely installed in the UK between 2011 and 2014. Popular Sunmaster models being the Sunmaster XS2000, Sunmaster XS3200 and the Sunmaster XS4300.
Mastervolt are no longer manufacturing or supporting grid connected solar PV inverters and should they be needed, we are not able to source parts to fix these inverters. Mastervolt still enjoy a strong presence in the off-grid solar PV market.
Mastervolt Sunmaster inverters have an LCD display on the front of the chassis, which providing it's working, will highlight any errors with the inverter or the solar PV system that it runs. The Soladin range doesn't have a display, instead they communicate their status through different sequences of flashing lights. We have listed and described common faults with Mastervolt Sunmaster and Mastervolt Soladin inverters and what action to take to resolve them below:

Mastervolt Sunmaster Inverter Faults and Warnings:Some of the advice we give related to identifying, confirming and or resolving some of the faults detailed below, starts with safely shutting down and restarting the inverter and the solar PV system. This is something that nearly all solar PV systems installed in the UK would have been designed to be carried out safely by the solar PV system owner. However, paperwork, schematics and manuals are not always clear or available, so if you have any concerns about how to do this, we will always be pleased to talk you through the process over the telephone at no charge.

I selected a similar SMA type. The next week Alex replaced it with a new inverter with WiFi connectivity. Everything is working perfectly (thanks Alex) in-addition I can now view my information through the Sunny Portal. A BIG thanks to Glen and Alex, superb service, highly recommended!!!!!" - David Powell, Worcester |
Recomendation via Facebook | "We had been let down by a failure on our system,and the manufacturer of the part was no longer trading. We called Glen during the afternoon and he was there in the evening. He examined the system and recommended a replacement manufacterer, promising to come back and fit in the new part once it arrived. We informed Glen of the arrival on a Friday PM, he was there fitting the new part by 10:30 on the following Monday. Of course it worked. That is what you call service, and guess who is looking after all our requirements in the future. Highly recommend this company." - Gill Spencer, Newbury |
Recomendation via Facebook | "In Balance contacted us promptly after we made an enquiry, Glen telephoned and arranged to visit our property to identify the fault, he arrived the following day! Brilliant as when the system is down it isn't earning us money. We decided to have a new inverter installed as our original one was 9 years old. Glen ordered the unit which was delivered to our property he then arrange to fit the unit the following day. He really could not have done it any quicker so thank you for that. Good job done for reasonable money. Highly recommended." - Geoff Thomas, Abingdon |

Review via Google | "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 |
Recomendation via Facebook | "We were very relieved to find Glen when our Solar Panel system stopped working, as our original supplier had gone out of business. We cannot praise Glen's persistence enough as he thoroughly reviewed the system to identify the faults and repair it, despite the searing heat of last summer. He also talked to Solar Edge and provided fault data to enable us to get a replacement part under warranty. Many thanks Glen for getting us up and running again!" - Jane Pearce, Highworth |
