@BitsAndBobs running the Cerbo on my cabin setup and the VRM portal is the bit I didn't know I needed — being able to check in remotely when I'm not there is genuinely useful.

@KevLee curious what your actual usable capacity looked like after eight months — are you still getting close to the rated capacity or have you noticed any degradation? Also wondering how it...

TracyRobinson | 1,203 posts @KevLee eight months of real-world use is exactly the kind of data we need on here rather than just unboxing videos, so cheers for sharing.

@PV_Master similar situation here — garden office, fed up with the extension lead running across the lawn. One thing I'd push back on: whatever capacity you think you need, add at least 30-40% on...

Been running a Victron SmartSolar MPPT 100/30 on my static for about 18 months now, paired with two Fogstar 100Ah LiFePO4 batteries. Total of 400W on the roof (two 200W Renogy panels).

@BevJackson64 — most modern BMS units expose cell-level data via Bluetooth. If the battery has a JBD or JK BMS (extremely common on eBay LiFePO4 packs), download the respective app and you'll see...

Liam1990 | 203 posts @PU_Sparks One thing I'd add from my motorhome setup — the JK BMS SoC will drift considerably if your shunt placement isn't correct.

Jonno25 | 47 posts @EcoFlow_Nerd Definitely not the only one! I ran a Delta Pro in my static near the Brecon Beacons for about eight months before upgrading to a proper lithium rack setup.

AlanWilson replied: Nice one @Gazza82, Epoch are solid batteries. One thing worth flagging specifically for narrowboats — keep your parallel cable lengths identical between both batteries, not...

Hey @Gazza82, great choice — Epoch are solid batteries and you'll notice the difference immediately over those tired AGMs! One thing worth flagging for a narrowboat specifically: make sure your...

T5Solar | 847 posts | Location: West Midlands, mostly on the cut @PanelHarry for a narrowboat specifically, 48v is the right call with that panel array.

After a scary moment last autumn where my leisure bank was too flat to run the bilge pump properly, I've been mulling over a separate small emergency battery just for critical boat stuff.
@RhysGrant raises a good point about Voc, and following on from that — also check your temperature coefficients between the two panel specs.
Finally pulled the trigger on a 200Ah LiFePO4 (the Fogstar Drift, since everyone here seems to rate them) and I'm now lying on the floor of my L3H2 Ducato wondering how on earth I'm going to make...

Good timing on this thread — I'm running a Victron Cerbo with a Studer inverter-charger on my narrowboat and faced exactly this. What worked well for me was using a CT clamp on the AC output wired...
@CallumHamilton83 looks like you got cut off twice over 😄 Had exactly this on my cabin setup — MultiPlus was calling float way too early on grey days.

@Ozzy yes, this caught me out too on my motorhome setup. Had a 360W array going into what I thought was a comfortably sized MPPT, then started seeing it clip on bright days with broken cloud cover...

@IanPearce56 Worth mentioning that winter shading can catch people out even when they think they've accounted for it.
Good points all round already, but one thing nobody's mentioned yet — coulomb counting drift is a real culprit here specifically in cold weather. LiFePO4 internal resistance increases noticeably...
