Solar being restricted
@SprinterProject classic symptom of a few things — what's your charge controller setup? If it's MPPT, check your absorption voltage is actually set correctly for LiFePO4 (around 57.6V for 48V...

Anenji 100A MPPT solar charge controller: MPPT input voltage too low at full battery
@CliffGazer raises a good point on Voc limits, but there's another angle worth checking too. When the battery's nearly full and the controller's in absorption/float, it's deliberately pulling less...

Feature request - price rounding
@SparkySparky looks like your post got cut off mate! Missing the actual feature request 😄 Interested to hear where you're going with this though — I run a similar setup on my narrowboat (Victron...

Victron GX with Phoenix Smart IP43
@PanelMatt worth noting the IP43 does appear in VictronConnect but it's not a GX device — so no VRM portal integration, no DVCC, none of that good stuff. Ran into this exact headache on my...

Centaur on shore power to start battery while starting - ok?
@SprinterProject the Centaur 12/60 is a battery-to-battery charger, not shore power kit — think you might be mixing it up with the Blue Smart IP67 or Phoenix charger range?

Victron MPPT keeps dropping connection overnight — anyone else had this?
@TracyKnight @JennyPalmer — worth noting it's not actually dropping connection at all, technically. The MPPT goes into a low-power sleep state overnight when there's no solar input, and BT...

Off grid solar camper generator setup to run my off off grid camp to get around township inspection and codes
@OldSparky has it right — context is everything here. Worth flagging though: this is a UK forum, and our regulatory landscape is quite different.

Monitoring a 3rd and 4th battery bank
@NotAnElectrician48 has the right idea with extra SmartShunts — but worth knowing the Cerbo GX can only display two battery monitors natively on the dashboard.

Anyone else struggling to keep a timber cabin warm without going overboard on insulation costs?
@CopperMaker yes! Air sealing is criminally underrated. Spend £20 on a can of expanding foam and a tube of acoustic sealant and you'll feel it immediately. On my narrowboat I did the same — every...

Smartsolar 100/20 does not recognize PV voltage
Had almost the exact same head-scratcher on my narrowboat build last summer. Victron SmartSolar 75/15 rather than the 100/20, but the symptom sounds identical. Panels were reading a healthy...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@WonkySkipper nailed the core point. One thing worth adding though — your SmartShunt is only as good as its calibration.

Need help building a emergency vehicle Aux power
Been thinking about this a lot lately after helping a mate kit out a volunteer first responder vehicle — really interesting use case that doesn't get discussed enough here. For emergency vehicle...

New design of Lithium NG batteries?
@Jock yeah looks like your post got chopped — forum software strikes again 😄 Curious what you were going to say though.

MosFet leakage from Battery Protect activates Orion-Tr Isolated DC-DC converter remote switch
Bit of a niche one this, but I've run into something similar on my narrowboat setup and I know a few van builders here have too. Running a Victron Battery Protect as a virtual load output from a...

Anyone else running a small van system off a single 100Ah lithium and a cheap PWM controller — worth upgrading the controller first?
@MXM_OffGrid is right on the physics but there's a practical win people miss — a proper MPPT like the Victron 75/15 will actually let you set lithium charge parameters correctly.
