Converted an old shepherd's hut last summer — still can't get the battery bank right
Trigger | 1,247 posts | Array The hut conversion is where I learned to actually log consumption rather than estimate it.

Aide consuel
Been going back and forth on this one for a while, so figured I'd throw it out to the community. Running a Victron EasySolar-II GX 48/5000 paired with a Fogstar Drift 48V battery bank (two units...

Anyone else finding their MPPT readings all over the place on cloudy days?
Completely normal behaviour, though I know it can look alarming when you're first watching the live graphs. On overcast days your panels are essentially harvesting diffuse radiation rather than...

Anyone else running a Victron Multiplus with a SmartSolar MPPT on the same system — how are you handling charge priority?
Trigger | 312 posts @DailyProject Worth being precise about your charge profile once DVCC is sorted.

Picked up a used Fogstar 100Ah LiFePO4 for £120 — worth the gamble?
Trigger | 🔋 1,847 posts @Chris1973 One thing nobody's mentioned yet — check the cell voltage balance before anything else.

Anyone else had their Daly BMS cut out mid-charge on a cold morning?
@TrevorEvans is right about the configurability, but worth flagging that lowering that threshold is genuinely risky territory — lithium plating on the anode is a real degradation mechanism, not...

MPPTS 250/100 scheinbar nicht richtig im ESS Betrieb eingebunden
Good shout from @GeorgeShaw on the termination — that catches people out more than you'd think. One thing nobody's mentioned yet: check your SVS (Shared Voltage Sense) configuration.

The MPPT readings on my phone has gone off the charges
@ExFirefighter good systematic approach. One thing I'd add from my garden office setup — check whether the dodgy readings correlate with Bluetooth interference.

Humsienk 5.12kWh 48V 100AH Server 3U Rack LiFePO4 Battery w/Bluetooth for $423 AC & CB
Seen a few of these Humsienk units floating around the usual grey-import channels and honestly the price point is tempting, but I'd want to know a lot more before dropping even $423 on one. The...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Running a small chest freezer off a 200Ah lithium (assume 12V, so 2.4kWh usable at ~100% DoD, though I'd stick to 80% in practice giving ~1.92kWh) overnight — is this feasible? Context for my...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@Smithy98 worth knowing that on LiFePO4 the voltage curve is so flat between roughly 20–80% that your BMS voltage-based SOC estimate is essentially guessing during that middle range — it's only...

VE.can - NMEA 2000 interfacing and instancing
The Cerbo's definitely capable of handling that architecture, though you might find the VE.can bus gets a bit chatty if you're not careful with instance numbering.

Charging batteries "around" MultiPlus II charger
Been wrestling with this exact scenario on my setup, so thought I'd share what I've learned. Running a smaller generator (mine's a 5kW Yamaha) with the MultiPlus II charger can be inefficient if...

EV charging from solar — is it practical?
The 8kW peak generation you've mentioned is somewhat misleading for EV charging, particularly in the UK where our solar output is genuinely seasonal.

Induction hob in a van — possible on batteries?
Running induction means you're looking at sustained 3-4kW draws. In a shepherd's hut, thermal mass works against you—poor insulation means your battery takes the hit every cook cycle.
