Battery Paula

Your 8kW looks impressive until you realise you're trying to charge a car in February with what amounts to a decent desk lamp.

Doubled up last year with Fogstars and suddenly winter doesn't feel like a battery anxiety simulator anymore—game changer for the shepherd's hut when December rolls round and the panels are...

Wrapped mine in a sleeping bag last winter and honestly can't believe it took me two years to figure that out — free insulation that actually works.

Ground faults on boats are a nightmare — water, salt spray, and vibration all having a go at your connections. Have you checked where the array splits?

Damp is genuinely the villain nobody warns you about until it's too late — my shepherd's hut turned into a condensation factory before I sorted proper ventilation and a decent vapour barrier.

Portable stations are just expensive paperweights if your draw is decent — you'll flatten them quicker than a narrowboat toilet tank in summer.

Series on a narrowboat is asking for trouble — one dodgy panel in cloud and your voltage tanks faster than your energy levels after lock season.

Matched my two Fogstar LiFePO4s in the shepherd's hut last year — same voltage, same capacity, same manufacturing date because I'm paranoid — and the BMS absolutely hates you when you don't...

Mate, the jump from PWM to MPPT is genuinely transformative — you'll wonder why you suffered through those dodgy years.

Mounted mine upside down in the shepherd's hut because apparently I don't read instructions — still works perfectly and the irony isn't lost on me.
