How To Calculate Battery Capacity For Ups. Number of cells per bank 40 x 6 240 cells. Measured in Amp-hrs AH VA Power Rating VA VA is the maximum charge of the battery.
This Calculator Does Not Account For InverterUPS Manufacturer Battery Protection Circuits Which May Cut Off Battery. It is measured is VA VoltsAmps. In this video how to calculate battery capacity Ah.
Add up all the VA then multiply this by a figure such as 12 or 125 which factors in future growth and system expansion.
Power factor of the home standard If you want to run 200W of appliances then 200 08 250VA. Calculate battery power of the UPS ie battery voltage AH time inverter efficiency battery volt AHload in watts. Include all of the devices the UPS will need to support. If you have 72Ah or 85Ah then if you round down this will give you a minimum and round up will give you a maximum.
