There are several options available for creating a simple but efficient emergency power supply.
We wish to show you some practical tips and ways for you to safeguard your building against a power cut.
In this variant a power generator is connected to the supply distributor installed in the house if there is a power failure and is started manually.
In this variant an installed power generator is started and stopped automatically if there is a power failure. You do not have to be at home in order to protect your house if there is a power failure.
Home installation and power feed must be handled only by a licensed electrical contractor. This guarantees safe and proper installation. The company will also be glad to advise you when selecting the correct emergency power supply. Tell your energy supplier about your plan and be sure of your power supplier's terms and conditions in the general terms and conditions document. The regulations vary state by state.
Also when its sounds quite tempting - a generator must not be run inside a closed building! The installation location must always be selected in such a way that there is adequate cooling air present and exhaust gases can escape into the open unhindered. Installation within buildings is only permissible in specially provided rooms. Please ask your district chimney sweep for advise if you have any questions. When installed outdoors, the generator should be fitted with some form of protection against the weather in order to prevent moisture getting in.
230V or 400V - which version is the correct one for me?
If you need a 400V power feed in an emergency (for example a cooker connection, workshop machines, etc), then a 400V supply is a correct criterion for you. There are some things to take into consideration concerning feed into the power network. 400V networks may only be supplied by a generator that is fitted with phase correction or a phase checking system in order to avoid any asymmetric loading (overload on a phase).
This could damage attached power consumers (for example televisions, computers). Our generators from the DUPLEX series have an electronic phase control system fitted as a standard fitting that allows feeding into a household network. All ENDRESS generators can be used for providing a 230V supply.
