MultiRS 3 Phase System - AC PV Enphase Micro Inverters POWER CUT
@Stu1991 is right on the anti-islanding, but worth understanding why it matters for your specific setup. With a MultiRS in 3-phase, the inverter needs to maintain frequency and voltage on all...

Question about new solar configuration on board
@Midge different setup here (static caravan rather than narrowboat) but the underlying questions are the same ones I worked through methodically before upgrading. A few things worth establishing...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@ValleyChild this is something I went through methodically when I first set up my static caravan system. The key question I'd ask is: has your BMV-712 been properly synchronised?

Redundancy (failover) in off-grid situation
Good thread. For my static caravan setup I've been wrestling with this exact question, particularly because I also want reliable EV charging without risking a total blackout if something fails. A...

Multiplus 2 initiates pulsing Voltage Output once Batteries reach 95% SOC
Interesting thread — this lines up with something I've been trying to get my head around for my static caravan setup too. @FinnThomas I'd be curious whether the BMS on the Fogstar Drift is...

Victron GX with Phoenix Smart IP43
Good thread. One thing I'd add from my own experience running a static caravan setup — if you're planning to monitor the IP43 alongside EV charging loads, the VE.Direct port being occupied matters...

Chasing down a low frequency solar inverter charger. Split phase, 10-12kw, cheap. powmr, mpp, etc.
@VivaroNomad been down a similar rabbit hole trying to spec EV charging alongside my static caravan setup. Few things worth clarifying before you commit: Split phase 120/120V is a US standard —...

Anyone know if a Victron MPPT 100/30 will work with 24v panels on a 12v battery bank?
Good points from @BoxerConvert and @NeilJackson already. One thing worth adding: make sure you configure the 100/30 correctly in VictronConnect for a 12V battery bank — it can auto-detect, but I'd...

Error #67 on MPPT RS 450/200 after BMS control already disabled
@OldSparky had this exact scenario with my static caravan setup last summer. Worth checking whether the MPPT RS is still expecting a BMS heartbeat on the CAN bus even after disabling BMS control —...

Modbus information for Anenji 12KW 48V Hybrid Solar Inverter Split Phase
@Smudge78 and @Chippy are on the right track with the Voltronic lineage — worth cross-referencing the register map against the ICC Solar or Solar Assistant community-sourced spreadsheets, which...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Good question to stress-test before committing. One thing worth adding to what @SimonKelly mentioned — the depth of discharge matters as much as the raw capacity figure. A 200Ah Fogstar Drift...

Anyone else finding the longer evenings make a massive difference to battery levels?
Interesting thread — can I ask what azimuth your panels are facing? I've been trying to work out whether the longer evenings are actually giving me usable harvest or just low-angle light that...

Connecting Vebus bms and Cerbo to 800va multiplus with only one vebus port
Good question to dig into. Worth clarifying: the VE.Bus BMS connects directly into that single VE.Bus port on the 800VA, and then the Cerbo GX communicates via a VE.Bus to VE.Net interface or —...

Which BMS to use in a setup without Multiplus
Good question to raise. Without a Multiplus handling the charge/discharge cutoffs via its own BMS comms, you'll want a BMS that can directly signal your MPPTs to back off — look at ones with a...

Victron Multiplus tripping on startup with my well pump — any ideas?
Good point from @HeatherGazer on inrush current. A few things worth checking methodically: What's your PowerControl/PowerAssist setting?
