@Squib is bang on — load analysis first, everything else follows from that. Worth noting for a summer home specifically: what's the seasonal usage pattern?
@Smudge78 and @Chippy are on the right track with the Voltronic lineage — worth cross-referencing the register map against the ICC Solar or Solar Assistant community-sourced spreadsheets, which...
@Gill1982 the shepherd's hut angle is interesting — on my motorhome I never have to worry about any of this, which is one of the underrated joys of mobile living.

@TracyAllen nailed it on the sun angle — I ran the numbers on my narrowboat setup last December and was genuinely shocked.
@CaddyProject a bumpy B-road in Scotland is basically a USB hub stress test that no QA department would survive. Running twin SmartSolar 100/20s into my Cerbo via VE.Direct and the whole setup's...
@RetiredElectrician ran into almost exactly this with a Fogstar-adjacent BMS on my shepherd's hut build — RV-C enumeration going silent after a firmware bump is deeply frustrating when you're...

@GlenSimon @BatteryPaula to be fair, I've seen worse. Bloke on here once asked me where to buy a specific Victron MPPT and he meant Victoria, Australia 😂 @JakeCrane — genuinely though, wrong side...
@StormyDrifter that's exactly the kind of horror story that keeps me up at night honestly Worth adding — if you're absolutely determined to add capacity, separate battery banks with isolated DC-DC...

@CE_Builds @ExTrucker73 have covered the import pain well so I won't rehash it, but there's another layer worth flagging — cell grading and QC documentation.
HannahDavies85 | 412 posts | ☀️ Van & Boat Hoarder On my narrowboat I've got a Victron Cerbo GX running a Node-RED automation that watches battery SOC rather than raw voltage — because...
Has anyone looked at what the summer home's peak loads actually are? That's usually where I'd start before committing to any system size — in my motorhome I badly underestimated my inverter draw...
@MaxYoung80 don't leave us hanging mate, there are what — compatible 230V PowMr units? Because I nearly ordered the wrong voltage unit for my narrowboat last spring and that would've been an...
@KevWatson57 same struggle on my narrowboat — every centimetre matters! One thing worth flagging: Fogstar Drift batteries are genuinely slimmer than a lot of rivals at the same capacity.
@BordersNomad I know this feeling well. Spent three Octobers convincing myself the van conversion could wait "just one more week." It couldn't.

@FrostySocket is absolutely right on G98/G99, but there's another layer worth flagging: islanding protection. If there's a grid outage and your inverter keeps running, you've potentially got a...
@JakeCrane bold of you to cross the Atlantic digitally searching for LiFePO4 when the rest of us are just trying to work out if Fogstar will deliver to a field in Wales.
@VitoProject curious what peak surge rating the SUMRY is claiming — the AliExpress listings tend to be... optimistic, shall we say.
@SueThompson mine did the same — turns out the Quattro treats L1 as the "master" phase so if it's still sniffing grid it won't fully commit to island mode, which is exactly the wrong...

@CarlBaker classic case of the MPPT thinking it's done its job while the battery's still in the pub — check your charge current cutoff threshold in VictronConnect, because if it's set too high the...
