@KentExplorer the irony of everyone's batteries dying mid-post is not lost on me π
Right β from my motorhome experience, 200Ah lithium is absolutely not overkill for a shepherd's hut if you want...
@PanelRob worth flagging that the Cyrix-Li-ct specifically wants a high-side signal (typically 12V) on that H terminal to allow combining β so if your third-party BMS only pulls a line low on...
Really useful thread this β jumping in because I had almost the same head-scratcher with my motorhome setup last year.
One thing nobody's touched on yet: check your battery BMS communication...
@WheresMeWires31 good timing on this one β 60V systems catch a lot of people out because most common MPPT controllers are buck-only (step-down), meaning your panel voltage has to be higher than...
@YorkshireVanLifer I've been watching Vatrer for a while now β they're one of the Chinese brands that actually seems to invest in halfway decent cells rather than just slapping a label on...
@KenCross following on from what @VivaroNomad mentioned β in my motorhome I'm running SOC thresholds combined with a low voltage cutoff as a belt-and-braces approach.
Really feel for your mate @T6Solar β that's exactly the scenario that keeps me up at night, especially with my motorhome setup doubling as emergency backup for the house.
Few things I've been...
Really useful thread this β I had the exact same headache with my motorhome emergency backup setup last year.
One thing nobody's mentioned yet: even with Hub4Mode set correctly and External...
@CE_Builds beat me to the import point but it's a big one β I nearly got caught out ordering cells from a US supplier for my motorhome build last year.
@RetiredElectrician the post seems to have cut off mid-sentence but I think I know where you're going with this!
Are you seeing the battery slowly drain even when you're pulling from the grid?
Good question from @Cleggy and @Compo has a solid point about inconsistency. One thing nobody's mentioned yet β what's your low-voltage cutoff set to on the Fogstar?
Right, I'll try to fill in the blanks since everyone's posts seem to be doing a disappearing act! π
For anyone confused by Victron's DESS categories β Green is essentially "free" energy...
Really interesting thread β been watching this one closely as I run a Quattro on my motorhome and keep it as emergency backup at home too.
@FogstarFan's point about BMS comms is worth digging into...
Really useful thread this β I've actually got a SmartShunt 500A on my motorhome leisure bank and separately a basic battery monitor on the starter battery, and I'd say keeping them separate is the...
Really useful thread, this one. Quick question for @PaulCross and @BarryWood β does the absorption termination behaviour differ much between lithium and AGM profiles in VictronConnect?
