Can i solder MOSFETs or any kind of transistors to make an inverter or (UPS Uninterruptable power supply) ?

Question

Can i solder MOSFETs or any kind of transistors to make an inverter or (UPS Uninterruptable power supply) ?

MOSFETs of any kind ?

the power that the battery/ies of inverter give will be :

P = V * I ?

so if we are using two batteries (two 12 V batteries are connected in series) i.e 24 V UPS or inverter and if the current rating of these two batteries are 90 AH then the power would be :

P = 24 * (90) = 24 * 90 = 2160 watts

or if we have 12 V UPS operating with two 12 V batteries in parllel then the power would be :

P = 12 * (90 + 90) = 12 * 180 = = 2160 watts

Are these right calculations ?

then what would be benefit of using parallel combination of batteries with an inverter or UPS ?

thanks

First of all, amp-hour rating is NOT the current rating of the battery, it is the amount of current it COULD deliver for 1 hour (or half that current for 2 hours) before it was discharged. Or twice that current for 1/2 hour.

Two identical batteries in parallel can deliver twice that current for one hour. 

The power out of a battery depends on the load. So you select the Inverter size depending on your load. Do not attempt to build one, until you have a lot more knowledge about circuits and electronics. Inverters are cheap. 



So, with the battery size you have, you could power a 2000 watt inverter for one hour, if it had a 2000 watt load. 

With two batteries in parallel, you could power a  4000 watt inverter for one hour, if it had a 4000 watt load, or a 2000 watt inverter for two hours, if it had a 2000 watt load. 

Or you can connect them in series and use a 24 volt inverter, but the power output remains the same, 4000 watts for 1 hour or 2000 watts for 2 hours or 1000 watts for 4 hours.
