@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...
@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) —...
@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.
Right, so if the BMZ isn't waking up properly, you're likely looking at a voltage threshold issue rather than just inrush.
The 48V form factor is where Eco-Worthy genuinely shine—they're compact enough for tight locker spaces but pack decent wattage.
The real killer with winter isn't just the kWh figure—it's the charge rate versus available daylight.
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...
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.
Two years of lurking is the right foundation—you'll have filtered out the dross and spotted what actually works long-term.
Have you checked your BMS settings in the app? I'd look at the cell voltage thresholds first—if they're set too tight, even minor imbalances trigger shutdown.
The real issue you'll hit isn't just the cells themselves—it's the BMS. Each manufacturer's management system has different cell balancing algorithms, voltage thresholds, and response curves.

@DaleVicky welcome aboard. Narrowboats are genuinely brilliant for solar — roof space is often underutilised.
Salvage route's solid but test everything with a cheap multimeter before assembly — I've seen batches where 30% were already internal short. @ZFS_OffGrid's right about laptops though.
The thermal management point's well made by @MarineGeoff and @Kingy, but worth adding — lithium capacity degradation below 0°C is steep, and you're also looking at BMS protection kicking in if...
The usable capacity point @DucatoDream and @FellKev have made is absolutely critical. I've made this mistake myself on my narrowboat — bought a 400Ah lithium bank thinking I'd have 400Ah...
