Creating a simple Inverter and LVD

Simple but very useful when the lights go out at night or an emergency when you are soldering suddenly the lights out too!

(once happened)

Although it cannot be for other equipment such as fans or others I don't think it is necessary because the power available in the battery is limited.

Mathematically, for example, with a 12V 3.5AH battery, the energy in the battery is only available around 42Watts / Hour or even less if the recharge is not optimal also if the battery condition is no longer prime.

For example, if you use equipment with a power of 42W, it can only afford less than an hour! why? Because the efficiency of the inverter is not up to 100%, not to mention the condition of the battery just now.

That is normal, if it is forced, it may take longer until the battery is deep discharging but the risk is that the battery will be damaged quickly.

To fix this, the inverter needs to be added with an LVD (Low Voltage Disconnect) circuit so that the battery operates as it should.

I guess maybe the use of inverters is limited to equipment that in emergency conditions is needed considering that the energy possessed is limited only to batteries.

Well here I will show you via video how an LVD works, both to keep the battery from deep discharging conditions and to guard against unwanted things such as short circuits.

Also PCB design/layout.
