Hi all,
Basically trying to do like some others have posted on various forums. Most of my day to day energy use is on my computer system at home.. WFH. I'd like to get one of the new EcoFlow Delta 2 units for $800 as it has the inverter in it, and I'd like to have one for portable use on drives. Given the long life of these batteries, during the day my energy use is .45c per KWh thanks to PGE passing on their fire/death bills on to us customers. Used to be half of this a couple years ago. Anyway, I thought.. can I run my PC (about 700 watts when gaming or 300 or so watts when surfing web, working, etc) and monitor with a handful of devices (usb audio, etc) on one of these 1000wh batteries for most of the day during peak times?
If my math works out, my monitor is about 100watts max, and most of the time computer is 600 or so. Assuming 750watts or so, I Assume this battery would last just about one hour.. give or take a little? Is that correct?
So I been looking at some DIY battery options, like the EG4, etc.. but the CATL EVE 3.2v cells are pretty affordable, about 1/2 that of other options, and from what I've read though they are from China, their Grade A Prismatic cells are top of the line. So 4 of them at 300ah work out to about $700 give or take when you get them. I've read that a 48v system is more efficient and better than running them at 12v as well. So I was thinking if I put them in parallel to have a 300ah 48v battery pack, that can charge the Ecoflow Delta 2.. it might give me a few hours of use total on my pc/monitor setup. Is this possible.. does it make any sense at all so that I can charge battery during offpeak hours and possibly with a long cable and solar panel in the back yard (about 20 feet away)? Or is it ridiculous/stupid to consider this.
The plan is to add more CATL even batteries to make it a bigger pack altogether. I assume I'll need a BMS for charging the EVE as well, and possibly some inverter or what not to convert solar panel and AC power to charge them?
Or is there a better way to go?
TL;DR want to run my PC/monitor that I work on 10 to 12 hours a day (for all purposes not just work) on battery power to reduce the cost I spend at day time energy costs.. aware that it will likely take a couple of years before "break even" with the cost of batteries/etc, but also want the ecoflow for portable use and power outage use situations.
Thanks.
