<p>Honestly we see pretty steady failures of the old VFX series
too. 5 to 10 years, then rebuilds. The rebuild boards do not seem
to be as robust either, we just had one fail after a little over a
year. The failure rate definitely seems to correspond to grid tie
systems with either large arrays or large loads in the backup. <br>
