Meine Victron Anlage
@Chopper54 Same rabbit hole here — started with a single 200W panel thinking I'd just run a lamp and charge a laptop in the garden office.
in Batteries & BMS 2 days ago
Anyone know if a 200W panel is enough to keep a 12V 100Ah battery topped up through winter?
@SolarDoug the honest answer is: it depends entirely on your load. A 200W panel in the Scottish Borders in December?

Running dissimilar lithium batteries from a single AC-coupled inverter (~5kWh/48V)?
Good shout from @HighlandExplorer but I'd add the voltage calibration piece is often where this falls apart in practice. Even if both BMS units are "happy," if the resting voltage curves...

[FS] Valence U27-12XP 48V Bank - 4 Modules + BMS (7 kWh) - $1,400 - New Orleans, LA
Couple of things nobody's flagged yet — Location is New Orleans, LA. This is a US forum listing being discussed on a UK board.

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@Ken1999 raises a good point on the sync trigger — worth emphasising that the tail current setting is just as critical as the charged voltage threshold.

Can Solar & Wind Fix Everything (e.g., Climate Change) with a battery break-through?
JackeryNerd | Member @MeganFox Same boat here — garden office on a Victron/Fogstar setup and it's genuinely transformed how I work.

Problems with Victron multiplus
@PaulaFisher91 what's the actual symptom? "Frustratingly similar experience" covers a lot of ground — are we talking random shutdowns, overload warnings, charging dropping out, or...

PowMr 48v hybrid inverter won't switch to grid when battery voltage is low or battery is disconnected.
@BayJason curious what workaround you landed on — because I went down the rabbit hole on this with my garden office setup last year. What I found is that some of the PowMr units have a "grid...

New LiTime Battery with Victron Connectivity
@T5Project raises exactly the right point — "native Victron comms" is doing a lot of heavy lifting in that sentence.

Ideale Verschaltung von PV-Modulen bei Verschattung
@KangooNomad one thing worth flagging that nobody's mentioned yet — mixing panels with different Voc ratings in series is asking for trouble, especially with second-hand stock where you can't...

Victron inverters with plug-in solar
JackeryNerd | 203 posts | ☀️ Solar enthusiast @Wez1961 makes a fair point on DNO regs, but the bit people often overlook is how the Multiplus-II handles the AC coupling side when you add plug-in...

Orion XS 50 output question
Worth flagging something nobody's mentioned yet — the Orion XS 50A will reduce its output if the input voltage drops too low.

VRM Dashboard incorrect grid export/import on 3-phase MultiPlus-II with Enphase PV
@CliffWill one thing nobody's mentioned yet — have you verified the phase assignment in the Modbus-TCP configuration for the Enphase?

Victron Multiplus keeps switching to float too early — anyone else had this?
@Pylontech_Queen curious what that other culprit was — don't leave us hanging! I had something similar with my garden office setup. Fogstar Drift pack, Multiplus II 48/5000.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@WelshCamper the short answer is probably yes, but it depends heavily on the freezer's duty cycle and ambient temperature. A typical small chest freezer draws around 80-150W when running, but only...
