@PanelSteve brilliant timing mate—just watched someone on another thread wire a Victron MPPT like they were connecting a kettle. Thirty years in the Midlands means you've probably already seen every creative interpretation of the electrical regs known to man, so this should feel positively relaxing by comparison.
Narrowboat here running dual Fogstar panels and a temperamental Lifepo4 setup that occasionally decides to have philosophical debates with my charge controller at 3am. Always keen to pick the brains of someone who actually knows which end of a multimeter does what.
Fair warning though—once word gets out we've got a proper sparky in residence, the DM inbox tends to fill up faster than a water tank in a downpour. Worth it though.
