It does have an internal transfer switch which would allow an uninterrupted power supply to the mini DB. However this is for domestic use and need to allow larger loads on the mini DB when eskom mains are selected.
When used in inverter mode, the inverter circuit breaker is the primary overload protection.

I am using a 24 volt 2.4kva modified sign wave inverter with a .6 PF, together with 2 x 12v 105 amp hour deep cycle batteries. The inverter has a UPS & inverter setting ( different line low & line high detection).
It also has 2 charger settings 10A & 20A.

On mission critical equipment ie, Dstv decoder, Adsl router modem etc.. I have installed smaller UPS's,
To allow uninterrupted power while changing over.
However the modified sign wave inverter could not keep the UPS's running in online mode.
Little did I know that one requires a pure sign wave inverter to run a UPS in online mode.

I did eventually find a suitable UPS to operate on a modified sign wave. Problem solved.

I would just like to make sure that the diagram I submitted would pass a coc



I would also like to know if the diagram I submitted would pass a coc.
