****A disclaimer, this thread contains material and discussions that is "...dangerous and not productive...". I guess that warning should satisfy everybody.

I thought I would start a new thread to get a discussion going about Pure Sine Wave Invertors. I will probably have a lot of questions about that, tomorrow.

they need to be sized near the intended load. They are not very eff esp when on 24/7 and no load, ie they have a stand by load until you get to big ones that sense the load and turn off when idle and/or have a remote.
It is silly to use a 12v DC wall wart via inverter when you can just use 12vDC directly with no losses.

AC Inverters are way better than just running 12v..... Like I said before many times get a small inverter they use less power.....
Most 12v appliances are cheaply made and aren't that efficient..... Don't believe me read all the problems people have with 12v systems...... But what do I know I've had a DC to AC system running worry free for 3 years now......
Plus I don't need no stinkin app to tell me how my system is running....... All you need is a visual numeral volt gauge....... Once you get your system up and running and your comfortable with it....

I am still thinking about the questions to ask. For now, the way I see it, some of my devices are better off just using the 12V directly. Unfortunately some of the other devices that I want to put on solar, are not 12V or less units. I think some need something like 14V, to maybe 18V, I think.
I am also thinking maybe an inverter could be setup to use in emergency situations, like a power outage. I guess I could set it up to use a coffee maker, maybe a 1100W microwave, things of that sort. Still thinking about this one.

Still thinking about this one. I agree with Tatto, propane (or charcoal in emergency situations) would be a better power source for cooking. Keep in mind that the inverter must be capable of powering the device, such as a 1100 watt microwave. But also keep in mind that you battery power must be able to power the inverter. 1100 watts at 110 volts = 10 amps. 1100 watts at 12 volts = 91.6 amps. Can your battery system handle a 92 amp draw? And for how long? |
