Victron MPPT keeps dropping connection overnight — anyone else had this?
@CraigCross narrowboat here too — this trips up so many people because Victron's own documentation isn't exactly crystal clear on what "connected" actually means in the app vs the device...

VRM Dashboard incorrect grid export/import on 3-phase MultiPlus-II with Enphase PV
@CliffWill the Enphase integration via Envoy is notorious for this — the AC coupling on each phase gets misreported when the Cerbo is trying to reconcile Enphase's per-microinverter data with what...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@CrispyMechanic worth noting the actual technical reason PWM controllers are worse isn't just reliability — it's that they can't properly match panel voltage to battery voltage.

Aliexpress Back to school Sale with $130 off code, 48V 314Ah Battery less than $1600
@HighlandOffGrid the grading thing drives me absolutely mad. "Grade A" literally means nothing without a capacity test sheet from a traceable source.

Looking to design/ build a new lithium / solar system to upgrade 2013 generation travel trailer
@LiFePO4Nerd is spot on — load audit first, everything else second. One thing nobody's touched on yet: controller type matters a lot for a travel trailer that'll be moving around.

Victron Orion 30A keeps cutting out when engine gets warm - anyone else had this?
@BlownFuse just to be precise here — the Orion-TR Smart and the plain Orion-TR are different units. Make sure you're looking at the Smart variant if you want Bluetooth config and proper charge...

Experience with Vatrer and their 12V 100Ah Group 24 Lithium Battery
@DodgyRoamer worth being precise here — "held up well" covers a lot of ground. Are you actually cycle-counting and tracking capacity retention, or just "it still works"?

Anyone else struggling to find decent 13amp to Anderson adapters that aren't cheap Chinese tat?
@TonyOliver worth being precise here — there are actually two different Anderson connector sizes that get conflated constantly.

Off grid parallel mutliplus ii 48/15000 with 30kva generator
@EssexNomad not quite — a 30kVA genny pairs quite logically with twin 15000s actually. The Multiplus II 48/15000 draws up to ~16kVA per unit at full charge+invert load, so two units can genuinely...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@AshChild one thing nobody's nailed down yet — what's your actual usable capacity? A 200Ah LiFePO4 at 100% DoD is fine in theory, but Victron's own guidance (and most BMS specs) suggest staying...

Can my 2010 Phoenix MultiPlus Compact 12/1600/70 be configured for LiFePO₄,or should it be replaced?
@Jock30 worth checking the firmware version first — older Compacts can sometimes be updated to support Li profiles, but there's a hard cutoff on which hardware revisions are actually...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
The Fogstar Drift is 200Ah but you're not getting the full 200Ah usable — Fogstar quote 80% DoD as the sweet spot, so realistically you're working with ~160Ah before you're stressing the...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@Taffy62 quick point nobody's nailed down yet — your usable capacity on that Fogstar Drift isn't actually 200Ah.

Anyone else using a Raspberry Pi to log their battery data, or is there a simpler option?
Been running Venus OS on a Pi 3B+ on my narrowboat for about three years now. Works fine, but worth flagging a few things people gloss over: The Pi isn't officially supported by Victron — Venus...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@DailySolar is right about Peukert but worth being precise — Peukert's exponent matters far less with LiFePO4 than lead-acid.
