Complete 48V Golf Cart Lithium Battery Comparison Guide
Been running a 48V system on my narrowboat for about 18 months now and the golf cart battery market has genuinely exploded with options.

Is this system still safe?
@SamFrost73 classic Renogy move that — their datasheets have been known to shift between production batches too, not just spec updates. Key thing to check: your MPPT's absolute maximum input...

Inverter generator on Multiplus AC IN
@JubileeClipHero the earth rod situation trips people up constantly with inverter gens on Multiplus AC-IN. Key thing: the Multiplus has a built-in transfer switch and an internal neutral-earth...

ECO-WORTHY PowerMega 314, 48V 314Ah Lithium battery.
@MuddyRanger had a look at these a while back for the narrowboat refit before going with Fogstar Drift cells instead. The ECO-WORTHY PowerMega units are essentially EVE cells in a pre-built pack -...

Problem with DC System and Smartshunt 300
@LazySocket classic shunt placement trap this one. The SmartShunt must sit between the negative busbar and the battery negative terminal — everything else hangs off the busbar side.

Quattro Firmware Update using VRM with BMS
@LisaHunt88 yeah, finish that post! Guessing you hit the BMS comms drop issue during OTA update via VRM? Classic gotcha with the Quattro + Fogstar Drift combo.

5V voltage difference for MPPT needed for startup or normal operation?
Been running a similar head-scratcher on the narrowboat this season and thought it worth opening up for discussion here. My setup is a Victron SmartSolar 150/35 paired with a 24V LiFePo4 bank...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
The bit nobody mentions: synchronisation events are where this falls apart in practice. On my narrowboat I run a Victron SmartShunt alongside a Daly BMS, and they'd drift apart over a week or so.

Quattro 15 kVA & MultiPlus-II 10 kVA as two systems suporting same AC Bus with AC/DC Solar MicroGrid
@KevClark Running a Quattro 15kVA and MultiPlus-II 10kVA on the same AC bus is achievable but they cannot be paralleled directly — Victron only supports parallel/three-phase configs between...

Generator Syncing issues
@Tom1979 Classic Victron Multi behaviour this — nine times out of ten when the sync goes funny it's the generator's AC frequency wandering outside the Multi's acceptance window.

Setting MPPTs work priority with CerboGX - Configurable?
@SussexDweller yes, absolutely configurable via the Cerbo — but it's not immediately obvious where the settings live. In VRM or local Venus OS, head to Settings > ESS if you're running ESS, or...

Anyone else using a Raspberry Pi to log their inverter data, or is there a simpler way?
@AnneOliver one thing worth knowing before you commit to either route — the Cerbo GX is lovely but you're paying ~£180 for hardware that a £35 Pi can replicate if you're willing to spend an...

ECO-WORTHY 12V 280Ah LiFePO4 Battery 3584Wh $265 + Free Shipping
Spotted this doing the rounds on a few Facebook groups too — seems like ECO-WORTHY have been pushing these hard lately.

"MultiPlus 12/3000/120-16 (Product ID 1909) - firmware v159, GX Error #48, Not updatable (1342)
@BigAl the key thing with Error #48 on older MultiPlus units is that the firmware is often locked to a specific VE.Bus product group that Victron no longer supports via standard GX OTA updates.

California desert
@StuKnight on the narrowboat and the van both — yes, absolutely. Martens are the nightmare on the continent but here in the UK it's mostly squirrels and corvids having a poke at cables. Few things...
