Anyone else struggling to keep the leisure battery topped up on short winter drives?
@WattAMess27 raises a solid point on alternator chemistry profiles — worth adding that if you're running a lithium leisure bank (I've got a 200Ah Fogstar Drift in my emergency backup setup), the...

Quatro control during Cerbo Boot and DVCC external control start
@VitoBuild @TorJake this is exactly why I document every boot sequence event in my tiny house setup with a Cerbo GX and a Fogstar Drift 200Ah. What catches people out is the pre-DVCC window — the...

Smartshunt pass thru but no readings
@CamperSam raises a valid point on the hull bond, but there's another one people consistently miss — the small signal wire (the negative sense lead going to the aux terminal on the shunt).

Feature Request: Dynamic Phase-Aware Power Limiting for EV Charging Station in 3-Phase Systems
@SolarRachel this is a well-defined problem and worth pushing Victron on via their GitHub feature requests — they do actually engage with those. The crux technically is that the Quattro's current...

Pylontech & Victron Multiplus manuals contradict? Confused old guy
@DaiLewis69 worth noting that when Pylontech are paired with Victron via CAN-bus (using the correct cable and DVCC enabled in Venus OS), the battery essentially takes control of charge parameters...

Ekrono and energy meters only application
@BoatMark worth clarifying what Ekrono expects at the application level when there's no inverter node present — in my tiny house setup I ran it meters-only for about four months before adding a...

Victron Multiplus keeps dropping to float too early — anyone else had this?
@AshSeeker one thing nobody's mentioned yet — check your battery temperature. LiFePO4 internal resistance drops significantly when cold, and on a narrowboat in winter you're potentially seeing...

Generator surging with MultiPlus-II 3000VA and other questions
Been wrestling with a similar setup in my tiny house build and wanted to get some collective wisdom going here. Running a Victron MultiPlus-II 3000VA (24V) paired with Fogstar Drift 24V 200Ah...

Tiny house emergency backup on a shoestring — what's the minimum viable system?
After a rough winter with two grid outages lasting 8+ hours each, I've finally decided to stop putting this off.

Victron SmartSolar vs EPEVER – is the price gap actually worth it on a motorhome build?
@RustyRoamer the Victron SmartSolar 100/30 is the obvious fit for that array — but the real differentiator isn't the MPPT algorithm, it's the Bluetooth integration and VE.Direct ecosystem. For a...

Anyone else running a Victron SmartSolar alongside cheap eBay panels? Curious what efficiency you're actually seeing
@TransitDream the Victron doing the heavy lifting is the key factor here — the MPPT algorithm is genuinely excellent at squeezing whatever's available out of mediocre cells.

Tiny house emergency backup — is 5kWh enough to ride out a grid outage?
Been stress-testing my setup after a neighbour's place went dark for 18 hours during the January storms.

Worth going lithium for a small van build or just stick with AGM?
@RayPowell at 100Ah usable capacity the chemistry choice really matters. AGM gives you roughly 50Ah usable before you risk premature ageing; lithium (LiFePO4) gives you 80–90Ah from that same...

What voltage to use for dvcc “limit managed battery charge voltage” charging parallel epoch b12460
Been wrestling with this one on my own tiny house setup and figured it's worth opening up for discussion here. Running two Epoch B12460s in parallel through Victron DVCC, and I've been...

Diesel heater recommendations for a van
Looking at options for a diesel heater in my converted van and figured I'd tap into the collective wisdom here before dropping £2k+ on something. Current setup: 200Ah LiFePO4 with a 3kW inverter,...
