#inverter

In other #home #hardware thoughts, I just had to replace my Panasonic microwave after it developed a front-panel fault which renders it completely unusable and, by all accounts, is de facto unrepairable. (The gist of it is that the power-level setting button becomes stuck "on". It's apparently a quite well-known problem.)

Anyway, it appears that since I last bought a microwave, Panasonic's patents on
#inverter power control for microwave ovens have expired, because now multiple brands offer inverter microwave ovens. And that means that AT LONG LAST, I was able to find a microwave (a Toshiba, in this case) that has all three of my most important features — inverter power control, humidity-sensor "smart" cooking and reheating, and an actual, handle to open the door instead of a stupid pushbutton. Why do I hate door pushbuttons? Because inevitably they start sticking after a while, no matter how many times you take the damned oven apart and clean and lubricate the linkage, and then opening the door becomes a two-hands operation. One hand to push the unlatch button, and the other to get a grip on the door, which doesn't have a handle, and pull it open.

Yes, yes,
yes, you idiot marketroids, I get it, the flush pushbutton is all sleek and shiny and modern and all that crap. But it doesn't work worth shit. It's awkward at best, and worse, it's unreliable. FORM IS SUPPOSED TO FOLLOW FUNCTION, not throw it out with the bathwater.

Every single microwave oven that has a door-unlatch button
and no door handle has failed functional design 101.

Edit: my friend shut down the system last night and brought it up again this morning, and now she says it works again. What (if anything) happened to the remote server is unclear.

A friend installed #photovoltaic #SolarPanels recently. She used a group-buying scheme organised by a company calling itself #SolarTogether.

This evening, the #inverter failed. She then discovered that the installer had gone bust earlier this month. It looks as if the inverter and the mobile app talk to a server run by the installer. Installer goes bust, server goes down, hundreds of inverters stop working at once.

I really hope Solar Together has a plan for sorting this out.

For people into #photovoltaics, do you ever consider dropping an inverter and going full DC?

The century old debate between Edison and Tesla might need a revision, because of the mode of energy production. We shift to a local production now and the main advantage of AC - ease of long range transfer - becomes irrelevant. And now we have easily accessible DC-to-DC electronic impulse converters so it's not even hard to serve a large range of devices.

Most of the devices we use are DC-powered anyway. Just drop the power supply and plug it directly to the wall socket. There could be a set of standard sockets - round for 10V, elipse for 12V, flower for 24V, triangle for 30V, square for 40V and pentagon for 50V. And ofc. USB for 5V because that's already a standard. So that you can't physically make a mistake.

Every single LED bulb has a tiny power supply in the lightbulb. That's why they break. It's not the diode, it's the PS. It's often very low quality. The diodes are fine.

It's an interesting thing to consider.

Ugh, is it only #Victron that can make a decent Solar PV app??

I've just bought a #MorningStar #Inverter, and the app connected fine the first time via bluetooth.
Now it just show a lame empty screen, even after a phone reboot and killing the app several times.

I emailed their support and got this reply:

"One thing we have noticed is if the SureSine has been discovered by your phone and is on the Bluetooth list, it interferes with the app."

I'm sorry... WHAT?? THAT IS TOTALLY HOW BLUETOOTH IS SUPPOSED TO WORK!! 🤬

"Try deleting it from your phone, rebooting the inverter and start with a fresh session of the app. That should help."

🤦 I hate #IoT apps

At least it has a network port and supports #ModBus (which is really why I bought it), so I need to learn about that next <sigh>

@aden_cabro No. It was not first. Similar #blackout happened 2003 in Italy.

By what happened in Spain/Europe there is design flaw in #inverter shutdown rules.

Those should not go down immediately, but ( in this Spain kind of conditions of short over- and under voltage) should start go down sequence which should take 15min. In that time if problems persist and in overvoltage shall produce nothing to sell.

During go down sequence, in case stabilized grid condition, go down sequence decease.

#solaredge ist auch so eine Firma, die zu schnell gewachsen ist und dann die guten Leute verloren hat.

Der Support ist unterirdisch schlecht mit langen Antwortzeiten.
Es gibt mehrere Setup-Apps für Elektriker, die teilweise defekte Konfigurationen erzeugen.

Und dann ist da die Lüftersteuerung der #Inverter noch vollkommen defekt und erzeugt nervige Geräusche statt einfach nur sauber wegzulüften.
