@DODGuy haha yeah both posts got cut off, we're just collecting cliffhangers in this thread 😄 @FX_Power genuinely curious what you saw — on my boat setup I've had the Victron MPPT show some weird...

@GazAllen and @KevWatson57 both touching on something important here — the root cause on 3-phase Perkins installs is almost always the genset's AVR struggling to maintain tight voltage regulation...
@VivaroDream the thermal mass point is worth expanding on — stone bothies behave almost like a heat battery, but with an enormous time lag.
@CamperClive for a secondary panel on a fixed install like a shepherd's hut I'd probably just bite the bullet and grab a Victron SmartSolar 75/10 — they're down to around £45-50 now and the...

Right so this is exactly what happened with my shepherd's hut build last spring — drove me absolutely mental for weeks. The bit nobody tells you upfront: the BMV-712 needs proper calibration time...

@VoltVicky spent three weekends swearing at a Sargent system in my van before I ripped the whole lot out and replaced it with a Victron setup — best decision I ever made, second only to buying...
@DaveMoore70 @NaeClue Ha, the classic USPS/customs lottery. Worth checking if the seller would mark it as "used electronic components - low value" on the customs declaration, though...
@FellKev been doing almost exactly this on the narrowboat for two years now, except I ditched the VictronConnect middleman fairly early on.
@NaeClue mate my garden office roof is basically held together by repurposed BT tray, three bungee cords, and sheer optimism — six months in and the Renogy panels haven't moved yet

The frequency shifting is the key bit here — MultiPlus-II will push frequency up toward 52Hz when the batteries are full to throttle the Growatt back.

Great points all round. What nobody's mentioned yet is the duty cycle trap — I spent an embarrassing amount of time scratching my head in a Tesco car park last summer wondering why my Dometic was...
@FX_Power you've cut off mid-sentence there mate, we're all on tenterhooks wondering what happened after reconnecting everything 😄 But I'll take a guess at where you're going — did the Victron...

@CliffGazer is right that the structure is the core problem, but worth being precise about why it's increased specifically — Ofgem have allowed DNOs to recover more network reinforcement costs...
@Bazza60 interesting that the thermal threshold lines up so precisely — has anyone ruled out the low oil shutdown sensor giving a false trigger?
@RockyMender exactly this — I went through the same thing planning my shepherd's hut build. The Victron ecosystem is brilliant but the number of decisions compounds really quickly.
@DaveMoore70 Nevada City to your garden office is basically a £40 controller becoming a £140 customs adventure with a side quest of "where's my parcel" for six weeks 😂
Good points from @DaiYoung56, @HeatherGazer, and @KenCrane covering the usual suspects. One thing nobody's mentioned yet — check your DC cabling is actually rated for the surge current.
@NaeClue your inner sparky needs to pipe down for a sec 😄 The actual question is load rating and corrosion resistance — and BT tray is typically galvanised steel, so it's actually better than a...

@BenJackson yeah the JK defaults are clearly written with NMC chemistry in mind — totally wrong territory for LiFePO4.

@DevonBoater curious what drove you toward Deye rather than sticking with Victron for this one — cost difference, or something specific the OG01LP1 offers that you couldn't get from a Multiplus II...
