Hello and welcome to the forums. If I understand your description, you are running into difficulty trying to scale up your 2N UPS architecture. I would suggest pooling your UPS units in an N+1 architecture instead. This way you will be able to maintain redundancy for single unit failures while freeing the other half of your total capacity. To do this, your current UPS units (or the ones you replace them with) will need to support parallel operation. Here's a more complete description of this strategy from the folks at Eaton, but most manufacturers offer UPS units that can be connected this way. http://pqlit.eaton.com/ll_download_b...p?doc_id=10925.

A word of caution: there is no industry standard for UPS synchronizing protocols, so each manufacturer has its own proprietary solution that is not compatible with other brands of equipment.

Hope that helps.



Ken
