The interface of a generator with auto-start to ensure that the Generator is running within an acceptable period so that the UPS batteries are not exhausted is therefore essential in certain situations.
Many companies would not know how long their UPS will last as the amount of equipment they support is usually added to or altered, and the UPS unit has never been tested under full load. Ideally all UPS equipment should be tested on a regular basis to ensure that it will actually perform when required and also the time period that it will provide support.
The load requirement of the UPS needs to be established to ensure it will support the required services before the selection and installation of a generator can be undertaken. The generator must be sized accordingly and an automatic changeover panel fitted so the whole process can take place without the need for human intervention.
In the event of a power outage the UPS will automatically take the load of all the equipment wired to it's distribution system. At this point the control panel will have seen the loss of supply from the grid and will call for the generator to start. The automatic changeover panel will take over from the batteries in the UPS and the UPS will now see the generator as a stable supply. As soon as a UPS establishes a stable supply it will start to re-charge the batteries within the unit to prepare for the changeover back to mains power when it is re-established. The generator, if correctly sized, will support the required load within the building and the business carries on as usual. Once the automatic changeover panel sees that a regular grid supply has returned then it will put the load back on the UPS batteries and then swap from these back to the grid. Once the connection has been made, then the generator will shut itself down and the UPS will recharge the batteries from the grid supply.
Generators come in many shapes and forms and not all will be suitable for provision to sensitive electrical equipment. We can supply both new and second user units all of which will come with either a manufacturer’s warranty or a guarantee from the suppliers of the second user equipment. It is worth noting that there are many units which have been installed within redundant buildings that have done very few hours for the age of the equipment, so don't dismiss the option of second user kit. Generators can also be run on different fuels, the most common of which is diesel, but there are other types which may also be more suitable.
Installation may be subject to planning permission if the site is near to residential dwellings so consultation on provision will be necessary in these circumstances.
Finally the Generator must be run periodically to make sure it is functioning correctly if and when it is required to perform it’s intended duty and it must also be subject to a service and maintenance regime.
