SOLA 4000 - Operation
4 Operating Modes Parallel and Parallel/Redundant Operation
4.5 Bypass Operation
The "Bypass Operation" mode is activated by a multiple inverter failure or overload
•If the load is greater than 110% of the load capacity of all available inverters, the static bypasses of all individual units will connect the load with the mains directly
•All inverter output switches (SSI) will open, inverters may continue to operate
•The rectifiers continue to charge the batteries
•If the load is reduced to 100% or less of the load capacity of all available inverters, the system switches automatically back to normal operation
•All bypasses always switch on together.
•If a standby unit was off at the time of the inverter failure/ overload, it will automatically switch ON and all units
4.6 Maintenance Bypass Operation
The "Maintenance Bypass Operation" mode is used to supply the load directly from mains during maintenance or repair work.
•During this mode, the individual functional components are completely separated from the load (e.g. for maintenance work)
•Power for the load will be supplied directly from mains through internal or external power switch(es) (IBY)
