I have read the electric crises thread here. This is a technical forum so i thought i should share an inverter circuit with the forum members. If any of you has basic knowledge of electronics, he/she can easily develop an inverter using the circuit i am sharing. I have noticed that this inverter circuit gives at least 30 to 50 percent more backup time than the premade inverters available in our Pakistani market and it is much more cheap as well.
I am right now using a 12V 85A Lead Acid AGS battery and it gives me almost 4 Hours of backup. My normal load is 4x25Watt energy savers (Prime) and one 52" ceeling fan(GFC).
Here is the circuit.
Since i have already built it, you can ask me if you have any questions. I will be more than happy to answer and to help my fellow Pakistanies stuck in this energy crises
I want to add that it will take 3000 to 4000 Rupees to build this circuit depending upon the parts prices in your nearby market.
