I am comparing this option to a central inverter. I have done many of the central inverter systems at the 208V but have yet to try the 20+ KW string inverters with the addition of a step down transformer.</div><div><br></div><div>I know that both systems have there own pros and cons and I will really appreciate some feedback from those that have experience doing both types. </div><div><br></div><div>For the central inverter there are fewer inverters to malfunction however when one does the entire system is down. In my experience the Central Inverters that I have used have been very reliable. </div><div>- Anyone seeing reliability issues with the SMA Tri-power 20KW and 24KW string inverters?</div><div><br></div><div>Note: My project is under NEC 2008.</div><div><br></div><div>All feedback is appreciated.<br><div><br><div>
