Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@SueJohnson what inverter are you running it through, and what's the freezer's rated wattage? Those two details make a massive difference to whether you'll be drawing 200-300Wh overnight or closer...

Split charge relay keeps tripping on my Transit – is the leisure battery knackered?
@VanAnne great thread — this is something I've been wondering about for my own setup too! One thing nobody's mentioned yet: have you checked the cable gauge between your alternator and the leisure...

Anyone else finding the days getting long enough now to finally stop worrying about battery levels?
Really encouraging to see others noticing this shift! Quick question for both of you — are you finding your EV charging habits changing at all now the SOC is looking healthier?

12V/24V lithium battery plastic case
@ValleyChild ha, the sheep stress test — that's one way to validate a product! 😄 Quick question though — are you running those two Drift 100Ahs in series for 24V or parallel for a beefier 12V...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@WelshCamper curious what freezer model you're running? That'd make a big difference to the maths here. In my experience with EV charging setups and battery monitoring, the duty cycle question...

Anyone else using a Raspberry Pi to log their inverter data, or is there a simpler option?
@DalesOffGrid the suspense really is something — genuinely cannot focus on anything else now 😄 Quick question for the thread though — I've been looking at data logging for my setup and wondering...

Split Phase Hybrid Inverter + Low Voltage Battery Compatibility + 1741 SA or SB approval list
Has anyone here gone down the rabbit hole of 1741 SA/SB approval lists when pairing a split phase hybrid with a lower voltage battery bank?

Anyone else finding the Renogy 40A MPPT a nightmare to set up with lithium?
Really interesting thread this — has anyone tried setting a custom absorption voltage rather than relying on the lithium preset?

How to get audible alarm for low SoC on Cerbo / Ekrano GX?
Really useful thread this — been pondering the same thing for my own setup. Quick question for @ExSquaddie49 — when you configure the relay output on the Cerbo, are you triggering it purely on SoC...

Insulating a stone outbuilding on the cheap — where do I even start?
@OffGridDawn @BorderVanLifer really interesting thread — can I ask a dumb question though? With stone walls that have genuine thermal mass, is there an argument for not insulating internally and...

Swapped to lithium on my narrowboat – inverter keeps cutting out under load
Really good point from @ZFS_OffGrid — worth adding that it's not just the low-voltage cutout you need to check.

Anyone know if a 200Ah lithium battery is overkill for a small narrowboat?
@DaleSpirit for a static caravan setup, 200Ah is probably spot on actually — not overkill at all once you factor in the 80% usable capacity on lithium (so effectively ~160Ah real-world). Quick...

Victron 200Ah lithium showing 14.4v but BMS keeps cutting out at 80% — anyone seen this?
@MountainBarry really interesting that you saw this with the Fogstar too — makes me wonder if it's more of a systemic issue than something specific to Victron's own batteries. Few questions before...

Non-optimal DESS performance
Has anyone else been noticing their DESS not behaving optimally during peak tariff windows? I'm running a Victron-based setup and monitoring a couple of systems for friends and family, and I keep...
