48v system with 57v solar. SmartSolar needs at least 60V+ input. Suggestion how to get there?
@LutonBuild worth checking if you can wire your panels in series rather than faffing about with the setup you've got.

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
@OllieThompson73 worth thinking about whether you'll ever want to expand — I started with 100Ah in my tiny house thinking it'd be plenty, ended up bolting on a second unit within six months.

Short circuit protection on 1000A NG BMS - what current level?
Been mulling this over for a while and thought I'd get some other opinions. Currently planning a 24v LiFePO4 build — probably around 560Ah with Fogstar Drift cells — to replace an ageing FLA bank.

Victron MPPT keeps dropping to float way too early — anyone else had this?
@Chalky yeah this bit me too on my tiny house setup. The default absorption time on Victron is often way too short for LiFePO4 — it's basically tuned for lead acid assumptions. Worth checking if...

Request To Victron To Provide Documentation On Storing Victron Smart Batteries At Lower SOC
Storing mine at around 50% over a fortnight away and it's been fine — two winters now with no drama.

Narrowboat solar setup – is 400W enough to run a 12V fridge full time?
Something people don't mention enough — panel orientation matters massively on a narrowboat. You're often running east-west along a canal with trees and lock infrastructure casting shade at the...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Worth adding — starting current (inrush) on compressors can spike quite high momentarily. Make sure your Fogstar BMS and any inverter you're running it through can handle that without tripping.

Cooler connexion
@WattKaren good question on the inrush — I measured mine (Alpicool C15) with a clamp meter and the startup spike was around 6-8A for maybe half a second before settling to ~2.5A running.

Prevent grid feed -in with RS Smart Solar RS48 6000 inverter
Similar situation to what a few people have raised elsewhere — running off a limited grid supply and wanting to boost capacity without accidentally pushing power back. In my case it's a static...

Trojan T105 vs lithium for a static narrowboat setup — worth the extra cost?
LiFePO4Fan | 203 posts Static narrowboat is actually where lithium starts making more sense to me, not less.

Victron MPPT keeps dropping to float way too early — anyone else had this?
@DevonNomad worth double-checking your absorption voltage setpoint too — I had mine dropping to float early because the voltage was set a touch low for my Fogstar Drift cells.

EV Charging Station W-104 GX Communication Warning after Network Change and Firmware Update
Had this exact issue pop up on my tiny house setup after a Venus OS Large update a few months back. The W-104 warning usually means the Cerbo's lost track of the EVCS on the network — worth...

Default charge algorithm for BlueSolar MPPT 75/10
@AlanPalman57 one thing worth flagging — if you're running LiFePO4 (hence my username lol) the default profile is completely wrong and potentially damaging.

Load battery at high energy costs while sufficient energy available in the battery
@FellKev incomplete post there mate, you've cut off mid-sentence after "Multiplus-II" — what's the actual question?

Anyone else noticed their energy bills going up even though they're barely on the grid anymore?
Yeah this has been grinding my gears for a while now. My Victron setup covers probably 85–90% of my usage depending on the season, and yet the standing charge alone has nearly doubled in the past...
