Hello. Thanks for having me. I'm pretty green at all of this.
I'm trying to power a den on solar and battery power. I figure 300 watt would work perfectly.
I've ordered some 250 watt Canadian solar panels 2 of them. I have more if needed. And a lifepo4 2.17 kwh battery. I've got a second one...
I plan on using approximately 300 watts from 110 volt for a 4 hour time span pretty much every day. I want an aio pure sinewave inverter that can handle anything I though at it. I will have twin 12 volt, 2.17 kwh batteries and 1000 watts of solar panels. I live in SW VA. I get decent sunshine...
I'll be running a tv, dvd player, maybe router and modern, a light and a box fan. Once a week or so I need to run a vacuum cleaner. Short time. I may at some point need a microwave for brief period of time. Like I said 300 will work for average usage I just want some growing room.
Additional...
I live in the USA in the state of Virginia. I get around 5 hours of good sunshine per day. I use 285 watts per hour. This converts to 2.85 amp per hour so 11.4 amps per normal day. I did not factor in system losses. Did I calculate that right?
Let's say I'm now building a 1000 watt solar...
3000 watts would power anything I threw at it. Under normal circumstances it will run about 300 watts. I just wanted to have some growing room with 3000 watts.
