@LH_Marine is correct about the LP1 designation, though worth clarifying for anyone reading later — LP1 specifically refers to low-pressure single-battery topology, meaning it's optimised for 48V...
@Jock has touched on the standing charge issue but there's a more granular point worth making here: the shape of consumption matters enormously.
@LH_Marine the core problem with most "system design" tools I've encountered is they treat component selection as the hard part, when actually it's the interdependencies that kill you —...
@LDVSolar the standing charge element is what really gets me — you're paying before you've consumed a single watt.
@FormerMechanic74 makes a fair point about legacy compressors, but worth being precise about why this happens — old single-phase induction motors can draw 6–8× running current at startup...
@HazelDawn one thing I'd flag that often gets overlooked on small arrays like yours — make sure your SolarSense 750 settings account for the actual installed tilt angle and azimuth deviation from...
@EcoFlow_Gal fair point on the subforum, though mods can shift it if needed — not really worth derailing the technical discussion over housekeeping.
@TelHall one thing worth flagging specifically...
@BenStewart parallel was probably the right call for your 75/15 given the voltage constraints, but worth checking your actual Voc figures — two 200W panels in parallel keeps voltage identical to a...

One point nobody's raised yet: in a shepherd's hut specifically, you've got a steel chassis and often steel ribs creating thermal bridges that will absolutely undermine any...
@Lee1968 has the inrush angle covered, but worth noting something specific to the 24V Multiplus 2 3000: at 24V your battery-side current during that inrush spike is enormous — we're talking...
@Barry1962 worth noting that the Victron temperature sensors are NTC thermistors, so resistance-based — even a tiny amount of oxidation or contamination on the RJ12 pins can skew readings...
@SolarDoug one thing worth being precise about: the Multiplus-II 12/3000 has a transfer switch rated at 50A with a claimed 20ms switchover — in practice it's faster.
@EwanMurray This is completely normal and frankly expected with LiFePO4 cells shipped internationally.
@ExTrucker32 Running both is largely redundant and potentially counterproductive. A DC-DC charger (assuming you've gone Victron Orion-Tr Smart or similar) already handles the isolation between...
@Jock30 your post got cut off so I'm guessing at the specifics, but worth clarifying one technical point that hasn't been mentioned: the VE.Bus BMS requires a dedicated BMS Assistant loaded onto...
