Get your solar inverter repairs completed quickly
Solar inverters can be the weak link in solar systems for a range of reasons – poor quality design/manufacture, operational faults and general wear and tear. Many systems fail due to inverters that, in most cases, have been replaced across the country due to continual faults. These early inverters are now out of warranty and most of the original installers have left the industry. Energy Stuff fills this gap by offering quality solar inverter repairs with the best inverter brands that are completed by a qualified installer.
While some of these units went through a repair phase during warranty most did not last and or the cost to remove and repair them was just too high. These inverters are usually in the 1.5kW to 3.0kW range and a simple replacement is the most effective remedial action.
Any supporting information you can provide when contacting us would be appreciated. This should include the Make and Model of your existing inverter, the size in kW or watts (1.5 or 1500) and if any error messages are being displayed. You should also check your paperwork to see if the unit is still under warranty which in most cases would be within 5 years of installation. Another time-saving idea is to photograph the inverter label which can provide us with valuable details on the unit.
We stock an extensive range of quality inverters and we have warehouse operations across the country. We can usually get a replacement inverter delivered to you within days and once received we will organise an accredited CEC solar installer to call in and swap it over.
While most inverters come with a five-year warranty most provide an extended warranty up to ten years and some run specials where they provide this for free. Ask about warranty when you discuss replacement units for an update.
Sometimes, troubleshooting your inverter can help understand and identify the best repair options:
- Look for fault codes and the colour of flashing lights as displayed on your inverter LCD screen.
- Rebooting your system can sometimes clear a fault. If your inverter does not have a label affixed to explain this process then download our Solar Inverter ShutDown and Reboot Procedure and follow the simple steps.
Transformer and Transformerless inverters – know the difference and the impact on you
There are three types of inverters, transformer, transformerless and micro. We will discuss the first two as they are the most common that are failing.
Transformerless (TL) inverters use a computerized multi-step process and electronic components to convert DC to high-frequency AC, back to DC, and ultimately to standard-frequency AC. TL inverters dominate the Australian market and work on the premise that in a grid-connected system, transformers are already in place in buildings or just a short way down the line. As such the individual transformer within the solar inverter becomes redundant.
Transformer-based inverters are becoming less common in Australia. Standard inverters have a transformer within them that synchronises the voltage with that of the grid and your appliances. They were widely used in systems prior to 2014 but since then we have seen a major swing to transformerless inverters due to their greater efficiency, smaller size, and lower costs making them attractive to home-owners and solar engineers alike.
Swapping out an old Standard Transformer inverter
We are still seeing a lot of these transformer type inverters (Aerosharp, Sharp being two of note) failing and we are left will little option but to replace them with like type units. There are few remaining transformer inverters left on the market and most are high-quality European units which have a great reputation. Unfortunately, they also come with a high cost which is double that of the transformerless units. When confronted with quotes to replace these older units we often get the question regarding repair which is no longer available as the companies have gone out of business. Moving to a transformerless system is also just as expensive due to the extra work to bring the whole system up to the new standard.
When swapping inverters some installers may suggest a transformerless option without upgrading the system and we caution clients against this from a safety perspective.
