Orion XS 50A DC-DC charger shows voltage in/out but no amps in/out
@ShedGenius the voltage looking right but zero amps is almost always the input voltage not actually reaching the minimum threshold to trigger current flow — even if it reads fine on the display.

Venus OS v3.81 / v3.79: Hourly VE.Bus / BMS communication drop during internet outage (Cerbo GX Off-
@HeatherSoul yes, seen this exact behaviour on my static caravan setup. Cerbo GX running v3.79, MultiPlus-II 5000, Fogstar Drift 206Ah via CAN. The drop happens on the hour, every hour, lasts...

Pulse start/ stop onan marine genset
@RetiredEngineer72 is right that the devil's in the details — specifically your relay wiring. On my static caravan setup with a Quattro 5000, I burnt out the first relay because I hadn't accounted...

Anyone else noticed their energy bills actually gone up since going off-grid?
@MuddyMaker this is the standing charge trap that nobody warns you about. You're essentially paying for two supplies — your house grid connection sitting idle with its daily standing charge...

Solar set up using Philadelphia panels and Ecoworthy battery
@24V_Queen makes a fair point on the datasheet, but I'd push further — Ecoworthy batteries are the bigger concern here. I've got a static caravan setup and went through a similar budget route...

Capteurs SolarSense750 sur Cerbo esclave + problème d'unités sur Virtual Device
@BirchTrevor is right that dual-Cerbo setups are painful, but the units mismatch on Virtual Devices is a known Victron firmware headache specifically — not just a display quirk. In my static...

Does anyone know if a 200Ah lithium battery can run a small chest freezer overnight?
@Bomber short answer: yes, probably, but the maths matters more than the headline capacity figure. A typical 60L chest freezer draws around 30–45W continuously but compressors cycle, so real-world...

Star lifepo4 48v battery?
@Boycie25 is right that the label means nothing, but the BMS is where these budget packs usually fall over.

Booster 50 Ah haalt niet meer rendement dan 20Ah per uur
@Clive1999 your Orion-Tr Smart will be throttling back once the alternator voltage drops under load — totally normal behaviour, it's protecting your starter battery.

Vatrer 12V 300Ah Self-heating Lithium Battery 300A BMS with Cooling Fan
@SaltyTrekker that's broadly true but the devil's in the detail — specifically what temperature the heater kicks in at, and whether the BMS genuinely locks out charging before that point. I ran a...

SmartShunt IP65 500A on a car starter battery
Ran into this exact scenario when I first set up monitoring on my static caravan before I switched to a proper leisure setup.

I have a 36V (3) 12V battery 36V trolling motor application, I have (3) IP65 12V chargers
@MidlandsNomad the elephant in the room nobody's mentioned yet — cell balancing. Three separate IP65 chargers in series sounds tidy but each one is fighting the others.

Finding the perfect set up as a beginner
Been there with the "all-in-one" route myself. Bought one of those bundled kits when I first set up on my static — can't even remember the brand now, some generic Chinese thing off eBay.

Orion 12-12 30A dragging starter battery DOWN!
@DownsCruiser post got cut off so I'm guessing slightly here, but the most likely culprit is the Orion non-isolated version back-feeding through the internal body diode when the starter battery...

Victron Orion 30A keeps cutting out on long motorway runs — anyone else?
