The Davidpoz channel on YouTube checks out these two massive SI6048-US-10 SMA inverters

Fantastic results!

These Sunny Island inverters from SMA are amazing. The model is SI6048-US-10 and they are in a pair for 120/240 volt split phase. Each inverter outputs 120v single phase. They communicate with each other to stay a perfect 180° out from the other one. This means 240v appliances will also work. I ran them up during a full load test. The goal was to see if they would handle outputting the claimed watts in the manual.

Dave is building a solar off grid system for my home and workshop. This will (hopefully) be able to power his home during blackouts, and grid-down situations. But, it also is a way to save on the electricity bill. The rated output per inverter is: 5,750w continuous. 7,000w for 30 min. 8,400w for 1 min. 11,000w for 3 seconds.

Inverters were purchased through eBay:
