Did my first laundry today running off solar panels. No battery needed. For those days when it is sunny. Panel DC voltage fed directly into a modified MSW inverter using only the H bridge section to create AC. The boost converter section is disconnected. We only do laundry when it is sunny anyway as it has to be line dry. Those new direct drive washers use hardly any power at all. I can't get used to not hearing the generator run!

That is cool. There is an increasing number of appliances that rectify AC to
DC, then use a variable frequency inverter to drive an AC motor. My mini
split units do, maybe your washer does too? The thought is, we need a
group of hackers who bypass the line AC and feed panel DC directly into
the variable frequency inverter. Maybe I will, but not this year. Bruce Roe -
Unfortunately, LG uses hard potting on all their electronics. Pump motor still has to have AC. I was surprised it worked at all with only 115V DC supplied to the inverter. I really need to add a 12V panel or two to compensate for a small cloud, other loads on the main panel, and high temperatures. This is a 60V array and two panels are switched from parallel to series to do wash. Running is generally way under 400W and no major surges.Comment

Why would you doubt me. About 15 years ago they were not potted and repairable. Not my last two machines. This is a water environment and nothing is repairable.Comment
