Sometimes You Can't Tell The ACs From The DCs, Next Generation Inverter

This is completely different, an inverter that only puts out 140V DC. This is the first I've seen of these, but for sure there will be more. It is sold with a listing that says it is 110V AC and no instruction manual. Likely because that manual says it is DC out and they had to remove it from packaging. Explaining how to use a DC supply is just too complicated for the general public. DC works fine for more than 90% of products because they have a universal 100-240V switching power supply. The sellers just hope all you pug in are small wall warts without transformers. I've run things for years with high voltage DC because it is more efficient. The neutral has the high voltage. Hot is at ground potential.

I've been thinking about running more things directly from DC, like the new inverter air conditioners. You trust these things not to catch fire on you?

I'm a big believer in blending. I have a clothes washer which can totally operate off solar panels alone. I did that for three years. We line dry so laundry was only on sunny days. Last year was the start of weird weather with more clouds than ever. I added an old car battery from town recycling that only had about 10AH. I set the inverter boost voltage just below power point of solar panels. When array voltage drops due to load and poor sun, the inverter will just kick in enough to keep things running. That may be as little as 5W or up to 100W. Haven't had the washer stop yet! There is a whole world of electronics the solar community has yet to discover. That inverter is well made for the price and I love it. It should be disclosed what it really is. The public understandably lacks the knowledge to use it.

@@opera5714 Wait, so the washer normally runs from DC straight from the panels, no charge controller? And then the DC-output-"inverter" pumps out amps if the panel voltage drops?

@@AltereggoLol1 The washer runs thru a MSW inverter using the H bridge section to create AC. Whatever the panel voltage is, that will be what the AC is coming out. For years I ran this with no battery. If a cloud passed over the washer would stop. I was always in the garage and I would just press start after the cloud passed. It wasn't a problem till weather patterns changed and now there are a lot more clouds. I activated the 12V to HV inverter section and changed the setpoint. It seldom uses the boost inverter except when big clouds move in. It is really a very simple trick but you won't find anyone else on YT who does it. All the popular channels are nothing but box openers with no technical knowledge.
