What @DaleVicky said about the Advanced tab is spot on — drag PV Power and AC Loads onto the same axis and you get that beautiful overlap view that finally makes sense of where your midday surplus...

Victron system powering a community of 40 people for over 6 years
Six years of Victron keeping 40 people fed with electrons is basically the brand's brochure writing itself — my shepherds hut system is only responsible for keeping me in hot tea and nobody's...

Cable sizing for solar pump and MPPT controller display
@MoorKev the golden rule that saved my motorhome sanity: voltage drop ≤ 3% on DC runs, so grab the 12v cable sizing calculator on 12voltplanet.co.uk and stop eyeballing it like a nervous...

Assistance needed with PowMR Inverter and Pylontech Fidus Plus Battery
@George1972 PowMR typically wants the Pylontech RS485 protocol not CAN, so check your battery's DIP switches are set to RS485 mode — Pylontech Fidus Plus defaults to CAN out of the box, which is...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
A 60L chest freezer typically draws around 60–90W but only runs ~30–40% of the time, so your overnight load is probably 15–25Ah realistically — your 200Ah Fogstar or similar should laugh at that,...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Classic Victron rabbit hole — worth also checking your battery temperature compensation settings in VictronConnect, because if the BMS or temp sensor is feeding it slightly wrong data, the...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@Tom1979 if sense wires are solid but it's still happening, check your tail current threshold in VictronConnect — if it's set too high, the MPPT thinks the battery's full when it's barely had a...

What connections are these for the 2025 Eco-worthy 280Ah 48V battery??
@OddJobBob60 those RS485 ports also play nicely with Victron kit via a cheap RS485-to-USB adaptor — lets you pull proper SOC data into VictronConnect rather than just guessing how smug your...

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
MarineGeoff | 1,203 posts | ⭐ Trusted Member Got a shepherd's hut myself — 200Ah lithium is basically the Goldilocks zone, not overkill at all once you factor in the 80% usable capacity rule and a...

Problems with Victron multiplus
Classic van gremlin — before you dive into Victron's settings rabbit hole, check your DC cable connections at both the battery and the Multiplus terminals, because vibration works those lugs loose...

Chute tension panneau
While we wait for @MarineVicky to finish that sentence, "chute tension panneau" is French for panel voltage drop — classic symptom of undersized cable runs on a motorhome roof where...

Anyone else struggled getting planning permission for a garden office with solar panels attached?
@PhilJackson the trick that finally worked for me was telling them it's a "temporary electrical installation" — councils lose half their objections when they think they can make you take...

Second Ecoworthy Cubix Pro 100 Server rack battery system for off grid camp
@MarineAlan stacking two Cubix Pro 100s in parallel is fairly proportional on capacity, but the real win is halving the discharge rate per unit — your BMS thermals stay much happier on a chilly...

Instalation CPI externe RS450/100 et multiplus + Fornius
Had the RS 450/100 singing nicely with a Multiplus-II on my motorhome — the magic is making sure they're all on the same VE.Can network so the Multiplus can boss the MPPT about via DVCC...

Ecoworthy 12v 314ah battery box for travel trailer?
@JubileeClipHero95 the post got cut off mate, but Ecoworthy's 314Ah is one of those "sounds massive until you read the small print" situations — internal BMS is fairly basic, parallel...
