Summary: Under $1800 for a 6kVA UPS? It's AMAZING! The first one has been performing flawlessly for months and we plan to order more as the business grows. We're using the UPS to isolate and protect a custom-made automation system from Germany that cost hundreds of thousands of dollars. It's cheap insurance and we believe this UPS will extend the life, the reliability and the "Up Time" of our automation by a factor of three or more.
