Thank you for all of the replies. I was finally able to take Steinman’s advice and try resistors between the positive and the third...

The whole concept of feedforward is that all the inputs drive some algorithm or lookup table to produce as you say a "best guess" at...

I'm not sure about terminology and this goes to maybe irrelevant nit-picking for this thread. But I would still call it feedforward as...

LFP going for <100usd/kwh this deal sounds crazy but maybe there is devil in the rebate details. Or they forgot to work out the...

Just filling my application form in now... ;)

-- You could at least in theory also do the feedforward to reference voltage from the AC output current. Analog domain only, no need...

Isn't the DC bus voltage already one part of feedforward? DC bus current is just additional feedforward to compensate for I*R losses in...

Why do think that it would be a problem? Wiring can handle it, the whole idea of gG fuse rating is that it can handle similar overload...

400 kWh for december so pretty much in line with my numbers.

Suprisingly neat/clean construction. Balance wires going trough holes in the metal brackets would be a bit worrying if used in vibrating...

Cheapest battery on aliexpress is not a great start. There is no lower limit on what kind of crap they sell on aliexpress. Plenty of...

Most common gG NH fuse will handle about 4x nominal current for 10 seconds before blowing. Or abouts 5x nominal for 5 seconds. Not...

This seem to be good example how everything else than Qgd*Rdson goes to worse when moving from Optimos 3 generation to Optimos 5...

For sure it is NOT rated for DC break at 400A. You better yank the handle really swiftly if you ever want to use it for breaking the...

Looks really easy in most of the US compared to Europe, let alone the northern parts of Europe like Finland. :whistle: 30 kWp panel set...

12v lugs seem to be on the other end of the inverter. Amp ”meter” seem to go up to 1200A and 1500W rating is for those wall outlets that...

There is not any standard. Manufacturers make whatever people(companies) seem to be buying and what the manufacturers can gobble up. And...

Storing energy to lifting mass(potential energy) is clearly out of question, some slightly less crazy or smaller economical disasters...

More human-sized example: 100kg weight lifted to 2 meter height is 2 kilojoules or 0.55 Wh. or about same amount of energy as...
