You do have the battery polarity correct, don't you?

Some hybrids do have the facility to draw a minimal load from the grid when in no-export mode (Deye certainly do). The idea being that any minor exports that may occur during load changes are absorbed by the constant import so that the inverter never, ever exports (some grid operators seem to...

Sorry, I can't sit through 7 minutes of that voice. 10 lines of text and some drawings works better for me :) I do note this comment mind.

30m to the CT ought to be no issue (does the inverter manual have a distance limit?) using 4 cores of the Cat-6 per side, although I'd probably use a 2-core flex (maybe 1.0 or 1.5mm2) rather than the Cat-6, keep it reasonably separated from the power cables. What you have drawn should function...

Nah, but they glow so you can find them when the power is out.

Me too also a 787 in about 5 hours, and on the daylight side of the planet!!

Not that specific shunt, but I'm going through a similar process. My 200A shunt used to hang off the battery bus-bar with the cable hanging off the bottom. But after reading a post on here where the shunt apparently failed on overheat and dropped the wire somewhere it shouldn't go I've had a...

This idea (using a craft-knife not the wheel-cutter just yet) seems to work best for me today.

Yeah, it was a 1961 G2 like this one https://wesellclassicbikes.co.uk/products/matchless-g2-250cc-1961 Back then it was a throwaway machine, now ...

How are you testing your panel output?

Just putting the lugs on the 50mm2 battery cable. I should have bought a hydraulic crimper!!! My 10-year-old, Indian-made, lever-type beast goes to 50mm2, my British-made (and ancient) body doesn't. Adding a 1m bar to the handle sorted it for the half-dozen I need today.

This, dear readers, is why we have forums!! It's so simple I wonder why I didn't think of it. I'll just run off and try it on the 35mm2, the 50mm crimps are somewhere on a delivery truck. Thanks for the "obnoxious music" warning. EDIT Well knock me sideways with a wet kipper, it only ruddy...

My "fairly fat" cable of choice is 35mm2 made up of 490 x 0.3mm diameter strands, this makes it a bit flexible. I've got some silicone insulated 50mm2 with a massive 10,000 strands (not really sure I believe that, but I'm not counting them) for a new job that's a bit tight on space, it's...

I would go for a proper 48V battery pack with a single 16S BMS. There's a risk of 4 x 12V packs going out of balance with one another with attendant issues. Just how much autonomy do you need from your batteries? Your panels are going to be generating about 25kWh per day (very much dependent...

This diagram is probably your best bet. With no PE from the grid itself the Grid-PE connection would be your local ground rod. When the grid is down the N-PE relay closes grounding the N on the Load output allowing your RCD/RCBOs to operate correctly.
