This is the VA-based version of tsiACGroupPinACW, giving the group's total apparent AC input power rather than real power, which matters when the group's modules or their connected loads collectively present a non-unity power factor to the shared AC feed. It is the more physically accurate figure to compare against the shared circuit's ampacity, since apparent power, not real power, determines actual current draw and heating on that shared feed. An admin sizing a new shared AC circuit breaker for this group's modules would base the sizing on this VA figure rather than the watts figure.
