- Is this for a single piece of equipment/panel? (or is for multiple loads)
- Are you prepared to hard wire this into your electrical system?
- Do you expect to grow and want an expandable solution?
1) If this large unit is to replace several small units, it might not be that great a deal to combine them. One 10kva unit costs way more than two 5kva units. ($1900 v $2500).
v.
2) The standard 30amp L630 outlet can only provide about 6000va of power. Therefore if you want to use these larger UPS units, you need to have a new 50amp circuit hardwired or 50amp outlet (both big bucks). Many people have ordered 7,8 and 10k systems with a 30amp input plugs, essentially getting a 5000va for a 10,000va price. Bottomline, invest in your electrical system if you need these units.
3) One of the worst calls i get is from people that have 10kva systems and want to upgrade. They have probably already invested about $4000 in a 10kva ups system (more if it was new), with the unit, some battery packs and the 50amp electrical. Once you goto the next step of 16kva, the unit, battery packs, and electrical system becomes obsolete. Plus the 16kva is an expensive step up anyway. Bottomline, if your panel needs 10kva now, consider using a Symmetra format. Their components are modular and can grow with you, up to to that 16kva size.
