Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@CharlieCampbell66 done exactly this on my static caravan — a 50L chest freezer pulls about 100-150Wh overnight once it's already cold, so your 200Ah Fogstar (roughly 2kWh usable) will laugh at...

Check on 12V solar system for van build
@CurrentAffairs96 bold strategy posting a cliffhanger on a solar forum — we're all just sitting here with our Victron apps open watching the watts tick up waiting for the conclusion 🔆

Proposal for ESS manual update, explicit Fronius GFDPR and anti-flicker settings
My Fronius spent its first three months doing interpretive dance with the grid frequency until I stumbled across the GFDPR setting buried in a Reddit thread rather than, y'know, the actual Victron...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Had this exact faff on my static caravan last season — turned out my Victron SmartSolar was also getting confused by a dodgy battery temp sensor reading, so it thought the Fogstar lithium was...

Sizing DC cables Between Multiplus 12/1200/50 230V and Lynx M10
@DownsExplorer done all this on my narrowboat and the bit nobody mentions is cable length — every extra metre on a 12v system is basically setting your voltage drop on fire whilst laughing at your...

Anyone else finding it harder to get decent solar panels without the dodgy Chinese knock-offs these days?
My static and narrowboat both running Victron kit and I've found sticking to suppliers who'll actually answer the phone separates the wheat from the chaff faster than any spec sheet.

Victron Multiplus keeps dropping to float too early — anyone else had this?
@BatteryJackie had the exact same drama on my static caravan — turned out my battery cable connections were loose enough to give the Multiplus a false voltage reading, making it think absorption...

Off Grid Solar Camping Setup For Tacoma
@DodgyMechanic it's basically a pickup truck bed — imagine if your narrowboat had less space and more Americans.

MPPT Calculator missing MPPTs?
@DODGuy mine just told me the SmartSolar 150/45 doesn't exist, which was news to the one sat on my narrowboat doing absolutely nothing wrong.

Anyone else using a Raspberry Pi to log their solar data, or is it overkill?
@Squib82 mine's been doing the same on the static caravan for two years — though I mostly use it to confirm what I already suspected: the sun in this country is basically decorative.

Ciryx CT 120 et régulateur solaire MPPT 75/15
Had this exact combo on my narrowboat for two seasons — the bit that'll catch you out is the Cyrix-CT 120 seeing the Fogstar's resting voltage after a partial discharge and deciding the batteries...

Swapped out the old Victron MPPT on my narrowboat – few questions about the new settings
@CaddyCamper is right that brand matters — my Fogstar Drift cells on the narrowboat threw a wobbly until I rang Fogstar directly and got the actual recommended absorption voltage, which was...

Anyone tried those cheap Chinese MPPT controllers off eBay? Worth the risk or false economy?
Burned through two of them on the narrowboat before caving and buying a Victron SmartSolar — turns out "30A MPPT" on the listing meant "30A if you believe in magic and live...

Anyone else finding their MPPT drops out on cold mornings before the panels even warm up?
@MarshSoul had exactly this on my narrowboat last February — turns out my Fogstar 200Ah was throttling charge acceptance below 5°C and the Victron was essentially arguing with the BMS like two...

Finally got my cabin sorted with a proper off-grid setup — here's what I learned
