Do you mean two current transformers (i.e. sensors)?

One problem I foresee with this agility is that it's dependent on so many factors beyond your control, like the economy, weather, how fast coal fired plants fall apart, how fast solar and wind gets installed, etc. It's all very well to look at the best cases, but how common are they now, and...

Done.

Yes, it's a mess. It's 14S of "normal" 2P cells all the same capacity. But in total, it's 16S, with one "hybrid" cell (160 Ah in parallel with two 100 Ah cells), and one "quad" (four 100 Ah cells in series). The idea was that the higher capacity "cells" would never get empty, yet they would...

Since we're doing a show and tell, here is an old photo of my system. Sorry, it's a bit wet to take a new photo today. This is a penny pinching setup. The larger cells are from an EV kit that I bought cheap at an auction; the smaller cells are also ex-EV, from an accidental short circuit that...

There can be, on particularly extreme weather days, which are becoming more frequent. I read somewhere that thousands of air conditioners were turned down by electric utility companies, on a sweltering hot day. Most new air conditioners have this "feature". It sounds really bad, until you...

So was $30-50k your share of the transformer upgrade, or the total? I know that iron, copper, and special oil designed to last for 50 years with little to no maintenance can get expensive. Interesting that they expose that sort of cost choice to end users these days. In the old days, it was...

Some of us do import Zappis (I believe that they are a British invention), I've never heard of an Ohme here (but there could be some here), and I'm pretty sure we can't get Octopus plans of any flavour. Though we do have energy company Octopus Investments; it doesn't seem to be associated with...

Hmmm. Claims are cheap, it seems to me. Once some unscrupulous vendor makes an exaggerated claim, some not-as-unscrupulous vendors feel that they have to make the same claim to compete. and there is a race to fantasy land. This is why we need battery testing farms.

North facing (in the northern hemisphere) is really bad; basically, you will need these panels to be on frames that stick up from the roof at about 45°. Your partner, and perhaps your neighbours and council might have something to say about that. West facing is OK; east and west facing panels...

It won't work because the contactors won't come on. To make them come on, you'd need complex CAN bus commands and PLC (Power Line Communications) hardware. The protocol document costs big money to buy, though you might possibly find the answers on-line. Damien McGuire is attempting CCS...
