Generators Sizing Calculations Part Ten Electrical Knowhow 4. analyse site conditions and access. once you’ve calculated the load size and factored in your running requirements, you’ll have a good idea of the amount of electrical input needed from a generator. the next step is to confirm that your power requirements are feasible given the conditions and location of your site. For equipment rated in amperes, you can convert amps to watts with the following formula: for resistive loads (most common type): wattage = amperes x volts. for reactive loads: wattage = amperes x volts x load factor. load factor is the ratio of your electric energy use in kilowatt hours to your peak demand in kilowatts.
Generator Sizing A Step By Step Guide Power Electrics Pdf Pdf 3 step method of how to adequately size a generator for house, camping, you name it. 1st step: make a wattage worksheet (for all simultaneous run electric devices) 2nd step: fill in running and starting wattages for each device. #3 sum all running wattages and add the highest starting wattage. what size generator do i need for my house calculator. When sizing generators for certain retail and commercial applications, a square foot measurement system is often used to calculate power requirements, using the following formula: retail: kw = 50 kw 10 watts sq. ft. commercial: kw = 30 kw 5 watts sq. ft. 1,200 w. 3,600 w. total. 2,950 w. 6,550 w. as you can see in our example above, if we add up all running watts of our appliances we get the number 2,950 – so we are well within the 4,000 running watts limit (850 700 50 150 1,200 = 2,950). How to use the generator sizing guide. list your appliances: start by listing all the devices you plan to power with the generator. include everything from lights and phones to larger appliances like fridges and heaters. check power requirements: look at the power consumption figures for each appliance (usually in watts) and note them down.

Step 2: choose a generator size. since the calculated load is 932kva, we want to make sure we have enough buffer room for future expansion as well as motor startup. the recommended safety factor is about 25%. in this situation we would most likely consider a 1,000kw, or 1,250kva generator with an 80% power factor for this application.
