Since UPS efficiency is higher at higher load factors, loading to 50% total for 2N system or 40% for each module is good from an efficiency point of view. The efficiency at this load factor was observed to be approximately XX%. This means that the UPS efficiency is about average for all systems benchmarked at this load factor.
