Auroroa Power One Solar Inverters
We have been using Aurora PowerOne inverters for our larger commercial jobs for a number of years.
The Aurora PowerOne has for some time been the best choice of inverter for 30kw systems.
Over the years we have tried out a few cheaper inverters but have not found anything that will last even their warranty period.
More recently we have started to use them in smaller residential systems and so far the failure rates have not been materially worse than with the SMA inverters (usually our preferred brand for residential systems).
Aurora do offer a slight cost advantage over SMA and in our view are the only other brand that can do this without a material fall in reliability.
