Mastervolt Solar Inverter

Are you having problems with your Mastervolt Inverter?

Mastervolt is a Dutch company that was founded in 1991 and who specialise in the management, conversion and storage of energy in the solar and marine sectors. Their Solar inverters include the Soladin and SunMaster range.

What is an Inverter?

The solar inverter converts the direct current (DC) from the Photovoltaic Panels into an alternating current (AC) that you can use in your home. The inverter also collects data from your system and allows you to monitor how your solar system is working. If the inverter isn't working properly then you home can't use the energy generated by your solar panels. 

Solar PV Inverter Lifespan & Warranties

The lifespan of your solar PV inverter varies greatly depending on which inverter you have, though it is generally expected to be around 10 years, though there are modern inverters that would be expected to last at least twice that. Recent manufacturers warranties reflect that with most being 10 years however older inverters are lower than this at around 5 years.

Common Problems

The inverter is where most of the hard work for your solar energy takes place and there are a couple of this that can go wrong
1. No Mains Voltage
2. Error Codes e.g. 'No Grid' or just a blank screen

Often, however, the problem isn't actually with the inverter but is elsewhere in the system. Usually this can be easy fixed, and we can get your solar energy system back up and working efficiently for you

Our Services

Our experienced engineers will conduct a thorough investigation, not just of the inverter but of your whole system to pinpoint where the problem is and get it resolved as quickly as possible.

Sometimes the inverter just can't be fixed. If this is the case & the inverter is still within it's manufacturers warranty, we will ensure that all the necessary details are available for you to claim back directly from the manufacturers. 

If the warranty has expired then we can assess your solar PV system using a Solar Design Program which calculates the best replacement inverter for you by reviewing all kinds of factors including the location of your home and the number and positioning of your panels.
