I discovered #Africa #photovoltaics #youtube today.

If you need competent info on how to wire an inverter in an arrangement that isn't covered by the manual - find a black dude with poor English. It will be flawless.

I wonder if the #africanMastodon could tell me: is English the main language used internationally on the continent? Or it depends? What's the #linguafranca there

Kind of a naive question about residential photovoltaics

How feasible is it to install a big battery at home to become self sufficient?

I was thinking 150 or 200 kWh? Do these systems exist, is sodium there yet, etc

There is space here for about a dozen 500 W or so panels, that’s just above 7 kWc as I was told (I don’t understand their math). Daily electricity usage is certainly less than 10 kWh all year, often closer to 6. Everything is electric, big spikes while cooking.

I know the summer would have a lot of over production that wouldn’t sell well, and spring/fall would probably be just about even; winter would likely need to charge at night (in the Paris area, France).

(I know how much the air/water heat pump makes this a crazy idea that requires cross seasonal storage that doesn’t exist yet, residentially, so let’s leave it out)

I just finished the first version of a small software for managing the balcony solar plant of some family members. It works completely without any cloud or any other people's computers or even an internet connection.

There's three panels and an inverter with a battery. Any power initially is used in the household, then if anything is left it's put into the battery for later use, or if the battery is full, fed it into the public grid (to get a small financial compensation). Or if you want to, you can override that and just charge the battery, or even charge it from the grid.

Of course the inverter originally needs a cloud connection and comes with an app that needs a cloud connection and obviously is described as AI-powered very smart whatever. But there is a documented API for getting and setting some values! Interoperability! Without the cloud, there's hardly any logic built in. So I had to create it myself.

It's just a few HTTP requests, json, a SQLite database, and some very basic HTML.

I like this idea very much. The more solar the better. Now, I would like to see more utilities provide home battery systems for resiliency across their service area

Caught between a rock and... Nevermind.

AQI was 107 in Taipei, American neocons used to rip into China for their horrendous AQI.
