The purpose of the inverter is to make "home-made" AC power from your battery's DC power, so you can power normal home appliances. So, yes, you can use that slow cooker using the output of the inverter. However, on high power, the cooker will draw about 2 Amp at 120 V, and the inverter will draw about 20 Amp from your 12 V battery to produce that. Your ...

Philippine power (in the American zones) is a worldwide one-off: it is simply North American style power, but with neutral omitted. Safety ground is still there, but it's halfway between the hots. Indeed, any Philippine appliance can come to the US, be plugged into a properly wired NEMA 6, and be happy as a clam. In the Euro-power zones of the ...

The 74LS170 is not inverted from input to output even with the open collector outputs when looked at logically (i.e. input pin to output pin); the datasheet truth table shows it, but a better source is the logic diagram. Looking at the inputs (at the top), the inputs are inverted prior to storage (in the red ellipse) and therefore what is actually stored ...

You are seeking two very different things: 1) solar+battery power during long power outages. 2) Backfeeding to the grid to unwind your electric meter. There is no magic faerie to just make all this work together. Grid-tie: There's a standard for that, called UL 1741. It was solved decades ago. It does one very important thing that perhaps you aren't ...

If your motor can tolerate a square wave, it is fairly easy to create a push-pull driver connected to a center-tapped transformer. You can use a transformer normally used for step-down reversed as a step-up. I successfully drove my telescope synchronous motor with a DIY circuit as I described. Sorry, I don't know where the schematic is. Edit: Here is a ...

If you simulate the system, you will see that the phase shift created by the motor severely distorts the sinewave and thereby creates harmonics. However, for some purely resistive load there does not seem to be a problem. Clearly, electric motors are not purely resistive load.
