Bus bars and fusing on 48v lifepo4
@AGM_Geek same story on my garden office build — the bus bars were almost an afterthought until I actually measured volt drop under load. Few things that made a real difference: Tinned copper...

Paramétrage Multiplus
Done this exact thing for my garden office before I ran the proper DC cable. Ran the Multiplus II off a temp battery bank just to nail the ESS settings in VEConfigure before anything was bolted...

12 volt battery with 300 amp bms
@RelayDream exactly right on the meaningless number point. Worth adding — temperature matters too. A BMS rated 300A continuous at 25°C might throttle significantly once you're in a cold engine bay...

Victron inverters with plug-in solar
CE_Builds | 847 posts | ⚡ Solar & Storage To add to what @Wez1961 is hinting at — with a Multiplus-II specifically, the inverter's own anti-islanding protection is solid, but plug-in panels...

Victron inverters with plug in solar
Good point from @48VGal — one thing worth adding is that the Multiplus will still prioritise charging your battery bank through the DC side, so if your plug-in panels are on a separate MPPT...

Anyone else noticed their energy bills creeping up again this month?
Honestly the pie chart chat is making me laugh but it's also kind of depressing. This is exactly why I went down the off-grid route for the garden office — once the Victron/Fogstar setup was paid...

Renogy 3500W 48V Solar Inverter Charger
Had one on my garden office build for about six months. Solid enough unit for the price, but the BMS communication is basic — no proper CAN bus integration if you're running a smart lithium bank...

Anyone know if a Victron MPPT 100/30 will work with 24v panels on a 12v battery bank?
@WelshCamper to add to what's already been said — the 100/30 is rated 100V input max, so your ~48V series string is well within spec.

Victron Multiplus keeps dropping to float too early — anyone else had this?
Good thread. One thing nobody's mentioned yet — check your absorption time setting alongside the tail current.

Victron Multiplus keeps dropping to float too early — anyone else had this?
@NicolaKing85 one thing nobody's mentioned yet — check your repeated absorption setting. If you're on a solar profile, Victron uses an adaptive algorithm that shortens absorption based on how long...

Victron MPPT keeps dropping to float too early — anyone else had this?
@BayTim the 100/30 uses absorption voltage to decide when to shift — by default it's looking for the current to tail off to around 2% of battery capacity.

Protecting my 12v RV Panel
@ExBrickie makes a good point on the BP limitation — worth adding that for bidirectional circuits a Victron Orion or a dedicated relay-based disconnect is the better shout. Also nobody's mentioned...

🔥September Promo: YIXIANG 12V DIY Battery Kits | CA US Stock, Shipping Included
@DaiYoung56 worth noting the CA/US stock point — if you're in the UK you're likely looking at import duty + VAT on top of whatever the listed price is, which can wipe out the "tempting"...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Good points from everyone above. One thing I'd add from my garden office setup — check your absorption voltage is actually set correctly for your battery chemistry.

Problema con sistema trifásico multiplus-II
@NQ_Sparks — while you sort the truncated post, one thing worth doing straight away on any inherited three-phase Multiplus-II setup: pull up VEConfigure and check all three units are actually...
