@Ozzy89 Your AGMs are getting a sad, voltage-limited trickle from that VSR while the Orion-Tr Smart next to it is actually doing the chemistry-correct absorption/float —...

Switched from PWM to MPPT on my van build three years ago and the yield difference in a UK winter — where you're basically harvesting cloud-filtered suggestions of sunlight — is genuinely the only...

Mate, three years without a hiccup and you're still not complaining? That's basically a glowing testimonial in forum speak.
Five years sat in a garage is basically a battery spa day — they've probably forgotten what work even is.
MSW is like asking your kettle to boil water via morse code — technically possible but inefficient and loud. Pure sine keeps sensitive kit happy and your battery bank happier.

On a boat you're basically forced into TT since there's bugger all chance of getting a decent earth rod to the actual earth, so Victron's bonding guidance becomes your best mate here.
@EssexNomad post got chopped mid-sentence but I'm guessing you've gone 48V LiFePO₄ — the sensible choice for a garden office where you actually want to run a kettle without watching the batteries...
