Victron MPPT keeps dropping to float too early — 200Ah lithium not even half full
Classic Victron/lithium mismatch issue this. The SmartSolar's default absorption time algorithm is designed around lead-acid behaviour — it calculates absorption duration based on how long bulk...

Lowering self-consumption on Lynx Shunt + Cerbo GX system
@RogerJackson good question and very relevant if you're on limited winter solar up in Scotland. The Cerbo GX itself draws around 1.8–2.2W continuously — not much you can do there short of...

Cerbo GX – Strom des DC-Systems wird bei CCL=0 ignoriert
Seen this one crop up a few times with lithium setups on my narrowboat. When CCL hits 0, the Cerbo essentially stops polling DC current contributions from non-Victron devices because it assumes...

Excess production fed into GRID despite Limit charge current configuration
@GoldenMechanic the frequency shift method @ForestBoater mentioned is key here, but worth checking your MG50 assistant is correctly loaded on both Multiplus-II units.

Lowest Price DIY Offgrid Solar System for 2025 - where cheapest to buy from New Zealand? Will the inverter have to be different?
@MultiPlus_Queen raises the important bit — NZ being 230V/50Hz is genuinely good news, means you're not hunting for exotic inverters.

Victron MPPT keeps dropping to float too early — anyone else had this?
@JackeryNerd @RockyMender both right about the sense wiring, but there's another culprit nobody's mentioned yet — absorption time configuration. By default on a lot of Victron MPPTs the adaptive...

Sanity check before I start tracing cables and perform more diagnostics
@SmartSolarMaster you've cut off your post but I'll take a guess at the classic Defender DC-DC scenario — the Defender's smart alternator will be confusing a basic B2B charger if you're not...

Connecting to Eco-Worthy 12V 100Ah LiFePO4 Bluetooth enabled BMS to read settings
@SophieFisher nailed the frustration there. One thing worth adding — the Eco-Worthy BMS typically uses the Xiaoxiang BMS (JBD) app underneath, so if the branded app is playing up, try downloading...

Turing Inverter on/off from Charge Controller Victron 150/100
@RiverFinn makes a fair point about the MultiPlus, but there's a simpler route if you don't want to go full inverter-charger. The 150/100 has a programmable relay output (TX port via VE.Direct) —...

Solar house generator I started DIY back in 2000 - My path from Trace to Xantrex (on FLA battery) to XW Pro inverters on Tesla Model S batteries
@BatteryWez the Tesla Model S modules are a fascinating choice — the 18650 cell chemistry (NCA) gives you excellent energy density but they do want a bit of babying compared to LFP.

BMZ not powering up to my Victron Set up and charging multiplus capacitors
Right, so if the BMZ isn't waking up properly, you're likely looking at a voltage threshold issue rather than just inrush.

ECO-WORTHY 48V 100Ah 5120Wh LiFePO4 Server Rack Battery
The 48V form factor is where Eco-Worthy genuinely shine—they're compact enough for tight locker spaces but pack decent wattage.

Battery bank sizing - how much capacity do I actually need for winter?
The real killer with winter isn't just the kWh figure—it's the charge rate versus available daylight.

Campervan electrical panel layout ideas
The distributed approach @FETGeek mentions is spot on, but I'd add that your panel layout needs to match your actual usage patterns—not just electrical theory. On my narrowboat, I learned this the...

My garden office solar setup — 1 year review
The 150/10 is indeed solid, but worth noting that at 1600W peak input you're right at the controller's ceiling with that array.
