Hi, The attached picture shows the solar inverter right next to the Tesla power wall, and right next to the consumer unit.
Can this be right.?....the Tesla power wall is a 5kW device...solar panel array voltages are usually around 50V...so that would mean some 100ADC in that cable...this surely cannot be right?

Why can’t that be right, treez?

I know very little about solar, other than how to spell it properly, but if you wire the cells in series, doesn't that mean you’ve got less current?

But I don’t see why #4 wire (100 Amp) makes you incredulous. I’ve got 100 amp service in my house, and I’m not surprised.

PV panel feeding my GT inverter here produce about 280V DC on a bright day and I have a 125A three-phase mains supply. I wish I could afford a Tesla car. I'm not even sure I could afford a Tesla wall plug!

String inverters are the most commonly used type, I presume also in UK. DC voltage range is e.g. 200 - 600 V, may be more.

Usually the priority is to minimize wire length which carries the greatest Amperes.
Example, the battery pack feeding the inverter should be close as possible.
At 12 or 24 or 48V the wiring may need to carry a few hundred Amperes for an extended time.

Other units carry lesser current, and less is lost if you have to locate new equipment to suit the physical layout of existing units.

My 6KW inverter is fed with 240VDC from two 6 panel series strings of 40VDC per panel with 10 metres of 10AWG wires at 10 Amperes each into two ports of the inverter located in the basement.
The 240VAC output connects with a 15metres AWG10 wiring to a 30 Ampere feedback (grid-tied) circuit breaker at the main panel also in the basement.
Everything runs fine.

The voltage per solar panel and the total series string voltage usually above 300 V may be your wrong assumption.
