off-grid power 0 - 2022-10-25
quite a few significant life events and my ongoing quest to be a more authentic human had me thinking about living off-grid despite living in the Guernsey suburban area.
my objective is to be self sufficient for power - specifically electricity. i choose solar for this.
i am much more aware of the cost of running individual appliances, computers, monitors, etc. for example: i am using a pi4 for nearly all my computer tasks - ryzen beast not run for over a week.
house build:
- as many panels as i can fit on a flat roof and south(ish) facing roof: 8 panels with an 3.5 Kw output.
- battery; telsa on order but i plan to switch to AGM batteries once i grok them to save loadsamoney forever. i will need to do this myself as this is outside the knowledge set of my current solar installer.
- grid connection to sell back excess electricity and as a backup should my solar system fail.
- thing to divert solar power to heat water.
- inverter to feed house (can't recall size at the moment, need to check details again).
none of this fitted yet:-(
cabin/site-shed:
- 2 out of 4 400w panels on a single string ground mounted running.
- charge controller.
- 4.8 Kwh battery bank.
- 3000 W inverter.
working for only 2 full days and weather is overcast, gales, rain, pestilence etc. so big win output on day 1 was 1.06 Kw:-) i may resort to petitioning Nut for more sun:-)
panels are ground mounted at a winter angle. i'm iterating on the frame design and hope to move to a beta frame today from the first alpha frame.
i consume less than 2 Kw per day excluding hot water heating (do not have yet) and cooking, washing machine, dryer (heat pump type). i can't see that my total needs exceed 3 Kw per day.
i have marker penned Kw loads on higher power items and i'm developing habits to only run one at a time: i only have 3 kw continuous available.
more to come on frame design, electrics connections, site, etc.
