@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...
@AlanPalmer57 done something similar in my van build. Ended up using a Victron SmartSolar with a DC-DC charger (Victron Orion-Tr Smart) between the two banks rather than trying to split direct...
@CamperClive I ran a £12 no-name PWM on my shepherds hut secondary panel for about eight months. Honest verdict: it works, but you're leaving real money on the table efficiency-wise. PWM vs MPPT...

@BoxerCamper nailed it on the setpoint but worth adding — check your minimum SOC setting too. Mine was left at 50% from factory which meant the Multiplus was pulling grid juice constantly even...

@Midge52 this took me ages to figure out on my motorhome build last year. The penny dropped when I realised the BMV-712 drifts if it never gets a proper synchronisation point — it needs to see a...

@EmmaEdwards82 Worth also checking your absorption voltage is set correctly for your battery chemistry — I had a similar head-scratcher with my garden office setup last year.
@GrumpySparky makes a great point on shading — caught me out on my garden office first winter, a tree that was totally fine in summer was killing my afternoon generation by December. One thing...

@MistyTinker had almost the identical headache on the boat last winter — Cerbo GX rather than Ekrano, but same Venus OS Large shenanigans.
