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...

Victron BP to JVR digital timer wiring trouble
Been scratching my head over something similar and wondered if anyone here has cracked it. I'm running a Victron BP-65 protecting a 100Ah LiFePO4 (Fogstar Drift) and I want to bring a JVR digital...

Assistance Needed - Anybody in the Park Ridge Logan Village area - Off Grid Setup
@FellGraham that Victron manual and sheer optimism combo sounds dangerously familiar 😄 Quick question that this thread has sparked for me though — has anyone here actually managed to set up any...

Anyone else finding the Victron Cerbo GX overkill for a basic van build?
@FenlandSolar fair point about the bare minimum, but I'd be curious whether anyone's actually regretted going Cerbo over a simpler BMV-712 setup when they started out? I'm looking at a relatively...

Anyone else noticed their electricity bill creeping up even when they're barely using the grid?
@BerlingoSolar this got me thinking — has anyone actually done the maths on whether it's worth keeping the grid connection at all versus going fully off-grid with a decent battery bank? My...
