This app is designed to give you an approximate idea of what size generator you need to run certain appliances in your home or office. For best results enter only the items you would wish to use during a blackout at any one time. For example: if you enter a microwave and a kettle, the app will assume you want to run them constantly. Things you should include may be heaters or aircons, fridges and freezers. You may decide you can turn off a heater or aircon while boiling the kettle, to keep the KVA down and the generator more affordable. You can delete items by swiping. You can delete entire rooms and their contents by swiping on the room name. In the settings tab you can delete the whole report or email a PDF generated report. Please let us know any features you would like to see added. Marty.
