Yea, I don't know enough about this topic to be even contemplating it as an idea!
48V volts DC is as high a voltage I wish to go to on safety grounds. I can grab hold of both my positive and negative bare bus bars with each hand and don't even get a tingle but I would not do it with wet hands or put my tongue to it like we all did back in the school days on the PP3 9v batteries.
The Nowty Towers battery banks,
18.7kW PV > 109MWh generated
Ripple 6.6kW Wind + 4.5kW PV > 27MWh generated
6 Other RE Coop's
105kWh EV storage
60kWh Home battery storage
40kWh Thermal storage
GSHP + A2A HP's
Rain water use > 520 m3
Have you ever put wire wool across the terminaks of a 9V battery?
An instant firelighter!
2.0 kW/4.62 MWh pa in Ripples, 4.5 kWp W-facing pv, 9.5 kWh batt
30 solar thermal tubes, 2MWh pa in Stockport, plus Congleton and Kinlochbervie Hydros,
Most travel by bike, walking or bus/train. Veg, fruit - and Bees!

No but I remember shorting out a Nicad AA battery with a length of solder and it just instantly melted. I always wondered how many amps were flowing to do that on a 1.2V battery.

Am not totally green when it comes to voltage, current and why DC is particularly hazardous. I am appropriately bricking it every time I have to probe the off load speed on the wind turbine at about 450VDC.
But I hadn't realised quite how deeply burried power access would be. Had naively imagined fooling whatever control systems are in place would be something the EV equivalent of people with remapping kit would be all over!
