SOLA 4000 - Operation

4 Operating Modes Parallel and Parallel/Redundant Operation

4.3 Battery Operation

The "Battery Operation" mode is activated by a mains failure or rectifier failure

•The rectifiers supply no power

•The batteries supply the required d.c. power to the inverters

•The inverters supply a.c. power to the load as described in 4.1

•Power will only be supplied to the load for a certain period of time depending on the battery capacity

•If there were stand-by units switched off at the time of the mains failure, all units will automatically switch ON in order to extend the battery autonomy time.

4.4 Operation with an Inverter Failure

This operating mode is activated by a failure in one or more invert- ers.

•As long as the load is not too great for the remaining units, the parallel system will stay in UPS (inverter) operation mode, otherwise see 4.5.

•The static inverter-switch(es) (SSI) of the defective unit(s) will open automatically, separating them from the load-busbar

•The rectifier(s) of the defective unit(s) will supply d.c. power to the battery (batteries) only if the respective rectifier is not defective.
