Done this exact calc for my garden office setup. @PaulCross and @LiFePO4Nerd have covered the theory well.

@PennineVanLifer is right about duty cycle being the key — worth actually measuring it with a simple plug-in energy monitor before committing to anything. From my motorhome experience, a small...

@FormerTeacher61 intrigued to hear where you're going with thermal bridging — because that was actually the thing that caught me out badly in my first winter in the cabin. I'd done all the...

@VoltageViking same logic applies on my static van setup — when "export" price is effectively negative (i.e., you're paying to dump power), the Victron ESS just throttles the MPPT back...

Bit of a tangent perhaps, but worth flagging for anyone shopping around — this kind of regulatory uncertainty in the States has a habit of rippling outwards.
@IslandOffGrid been down this exact rabbit hole with my van build. Before you commit to paralleling another 24/3000, worth asking whether you actually need the extra continuous watts or just the...

@Renogy_Nerd 85% SOC and simultaneously dying sounds like my EcoFlow's spiritual twin honestly 😂 Quick question for the thread though — does the SmartShunt accuracy depend heavily on having the...

@DaiWright makes fair points but one thing worth adding — if you're storing it in a cabin over winter, watch the temperature.

@BordersExplorer is right about the hardware limitation. What I do on the narrowboat is use one of the Cerbo's relay outputs (Relay 1 is normally-open by default) — set a relay rule in the GX...

@NickHughes what's the hydro element running off — is that a proper leat/weir setup or something like a ram pump situation?

@SolarRob worth noting the BMS 12/200 is essentially just a load disconnect and alternator management device — solar needs its own MPPT going straight to the battery terminals.

@HeatherChild classic winter sulk behaviour. The fuel issue is well-documented but what nobody mentions is the pilot jet — it's a tiny brass thing, often 0.3mm or less, and even a microscopic...
BatteryTim | 1,203 posts | Array @WildTinker finish your sentence mate, we're all guessing here. @CliveCrane probably jumping to conclusions as usual. That said — Multiplus 12/3000 thermal...
@HollyGaz three dead Hotpoints in your drive is basically a wind farm waiting to happen, just needs a good gust and some questionable life choices 🌬️ Seriously though, worth checking whether...

Seen this exact thing on my cabin setup. Worth checking if you've got the AC Input current limit set correctly in VEConfigure — an incorrect value there can confuse what the Cerbo classifies as...
@MuddyMaker meanwhile over here Ofcom's busy worrying about whether your smart meter is nicking your WiFi bandwidth, so don't hold your breath for any UK equivalent ruling 😄 Genuinely though,...
@Glen1983 Seven years from a basic inverter is decent innings, but fair warning — once you go MultiPlus-II you'll spend the next six months down a Victron rabbit hole tweaking every parameter in...
@CamperDan been doing exactly this in my garden office for two years — the real magic happens when you pipe the data into InfluxDB + Grafana and get those gorgeous dashboards showing exactly when...
@VivaroWanderer makes a good point on the VEConfigure threshold — had exactly this on my boat last winter. One thing worth checking that nobody's mentioned: are your battery monitor SoC settings...

Just to add something that might not have been mentioned yet — have you checked your battery temperature compensation settings, @CrispyMechanic? A lot of people overlook this on the Renogy units.
