@SolarNotSure has the battery capacity angle covered, but worth checking one more thing: the absorption voltage threshold. If the previous owner tweaked the charge profile to suit a different...

@FormerMechanic15 ran almost exactly this on my narrowboat for two seasons — Victron SmartSolar doing the heavy lifting on the roof array, a Renogy 40A handling a smaller tilt-mounted panel on the...
KMV_Marine | Posts: 312 @DailyConvert To add to what @WattRoger is getting at — the Fogstar Drift specifically has low-temperature charge protection built into the BMS, which will cut charging...

After two seasons running a basic split charge relay setup in my Transit-based camper, I finally took the plunge last month and upgraded to a Victron SmartShunt 500A paired with a Cyrix-Li-Ct...

Shunt_Guy | Posts: 2,156 Dead right about placement mattering. One thing I'd add that's often overlooked — inverter orientation.

@IanStevens one thing nobody's touched on yet — don't forget to factor in your cable run from the panel to the controller.

Been trying to work out how much battery storage I actually need for a small cabin build. It's a weekend-use place mostly, but I'd like it to be liveable for longer stretches in winter too.

@TrevorHughes I went through exactly this when planning my narrowboat setup. Ended up on 12V because nearly everything I wanted — 12V lighting, water pump, diesel heater — ran natively on it, so...

Hey @DustyCaptain — something nobody's mentioned yet is charging time relative to your actual drive cycles.

I've had my 200W panel setup running since last spring and overall I'm pretty chuffed with it, but lately I've been noticing the MPPT 100/30 barely seems to get going when we have those thick...

LochChild | 203 posts Had this exact thing with my shepherd's hut setup. Turned out my SmartShunt's "tail current" setting was way too high — it was calling the battery "full"...

@GemmaCooper86 and @RogerKnight have covered the redundancy angle well, but there's a practical edge case worth flagging: if your B2B ever fails mid-trip, a latent relay gives you a rudimentary...

CotswoldOffGrid replied: @MoorRuss mate, I feel this post in my soul. Running a static on the edge of the Cotswolds and honestly December/January are brutal.

Really enjoyed reading through everyone's setups here. I went with a Nissan Leaf Gen 2 40 kWh pack about eight months ago — similar starting point to @GlenLover but the newer chemistry holds up a...

MidlandsExplorer | 203 posts Worth adding that your parallel battery configuration makes accurate SOC readings even trickier, @TimGraham.

Really timely thread @RayHunt. We had a 14-hour outage here in mid-Wales last February — storm damage took out a substation.
