Power optimizer

Power optimizer

I was reading about micro-inverters, which are becoming a more popular option over string-inverters for grid-tied solar. The idea with microinverters, is rather then have a big inverter, you have many small ones, which use smaller film capacitors which are less likely to fail. You also get the advantage of having MPPT tracking on each panel seperately. But what if you just want DC power out of each panel, but don't want to the disadvantage of connecting a large number of panels in series and hooking it up to a centralized solar controller? You could use a power optimizer, which adjusts the resistance of the power floating out panel to get the maximum output from each individual panel. I would imagine you would also use a solar controller to avoid overcharging your batteries, and floating them when the proper time comes. Interesting stuff.

Smart Meters

I wonder how long before electric companies start billing consumers for apparent power rather then real power using smart meters in New York.

I predict that will be a political shit-show πŸ’© when some people’s bills go up dramatically, especially those people that have a lot of devices with capacitive droppers or run big electric motors like laundry machines with shitty power factors. ✊ But maybe it will encourage better, more energy efficient appliances. ♻️

The moral of the story, is that people don’t like it when they “get free stuff by stealing from other people and then guberment takes their free electricity away.” πŸ”Œ

How Prepared Am I For the Coming Shocks?

I often wonder how prepared I am for the overwhelming evidence that in coming decades the economy and society at large is going to face increased crisis over dwindling oil supplies with increased demand for energy, with climate change pushing our infrastructure and natural resources into crisis. β›½

I am carefully investing, taking advantage of grow of the economy. But what if people like Bill McKibbean and nearly ever other rational person is right — growth is not indefinite? πŸ“ˆWhat happens if the stock market and economy stop growing larger each year — at least over the long-range horizon. Then I guess I’m screwed, as most of my investments are market based — diversified yes, but still based on the premises of a forever growing economy.🌎

I do spend a lot of time reading and studying videos about bushcraft, off-grid living, hunting and fishing. I’m probably more comfortable in the wilderness then many Americans. But I’m no serious outdoorsman, I rely on the plastic bagged food and cheap oil as much as anybody else. If the markets are in a permanent state of collapse, the funding I need to buy land and my off-grid cabin will vanish.πŸ“‰

I am not willing to plunk a bunch of money into gold,Β  πŸ’° or other questionable assets. Even land or a house that I’m not going to use for a few decades seems like a bad investment. The market, carefully invested in a place is to be if you want to grow your money for tomorrow. But I think many people will be in the same boat as me if the economy permanently changes, although I think with careful saving, and no debt, I’ll still come out ahead.

And just as important as money, learning new skills, especially with natural resources and the basics that make up our world πŸ€”is invaluable in succeeding in an economy that may collapse in the future as pressures in the oil markets and climate change take their toll on society.
