Also for the power parallel system, the automatic sharing control of AC current
equalizes the currents of “n” units and reduces the offset to less than 10% under any
load condition.
The load is supplied by the inverters in parallel also in the event of an instantaneous
overload
“n x 200%” of the nominal load of the single unit.
In the event that a failure occurs to one of the units, the load is switched to the
Emergency Line (Bypass), like in the case of a UPS in single configuration.
