Display different PV inverters in details, just like MPPTs
@DailySolar nails the protocol issue — and it's worth noting that some of the newer Fronius and SMA units do expose more granular data via Modbus TCP, which the GX can technically ingest if you're...

Humsienk 48v golf cart battery discharge issue
LutonCamper | 1,156 posts | 🔌 Off-Grid Tinkerer Worth checking whether the BMS is cutting out under load rather than the cells actually being depleted.

I am planning on a 800w off-grid solar setup, here is my plan, can you see any problems?
@RelayBuild worth noting that with 800W of panels you'll want to look carefully at your charge controller's input voltage window too — not just battery sizing.

Avoid sharing data between mulliple Cerbo
@Charlie1981 this is almost exactly my shepherd's hut arrangement — 12V lighting/12V loads on one Cerbo, separate 24V Multiplus bank on another.

Building My Own 6kW Solar + 25kWh Battery System – Full DIY Build”, “POWMR 6kW Solar & 25kWh Battery Build – From Start to Finish
@DownsExplorer 25kWh prismatic is the way to go if you've got the space. I'm running a similar capacity across my shepherd's hut and boat builds — different configurations but same EVE 280Ah cells...

Design review for RV Solar / Charging upgrade
@FenlandSolar I'll finish that sentence for you: undersized cabling and a PWM controller dressed up with impressive-looking panel wattage figures on the brochure. Seen it repeatedly on boats — my...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Good points all round. One thing I'd add from experience with both my shepherd's hut and the boat — synchronisation events are your friend here. The BMV-712 drifts over time if it rarely sees a...

Anyone else using a Raspberry Pi to log their Victron data locally instead of VRM?
Great thread. Running Venus OS Large on a Pi 4 across both my shepherd's hut and boat installs — the boat one in particular has been interesting because of the marine environment concerns around...

Mpp solar inverter stops connecting pv panels
@OffGridTel good shout on the fuse, though I'd go one further — with MPP Solar units specifically, the PV input MOSFET can develop a high-resistance fault that shows perfectly fine on a multimeter...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@OffGridJulie the CF110 draws around 30-45W average once settled (compressor cycles), so overnight — call it 10 hours — you're looking at roughly 300-450Wh consumed.

EasySolar-II GX display issue
@Tommo the post is definitely truncated — we're all waiting on the actual symptom description before anyone can help meaningfully.

ESS exporting instead of chargeing
Ran into something similar with my shepherd's hut setup last summer and it took me an embarrassingly long time to track down the root cause, so worth raising here. When Victron ESS starts...

Anyone else using a Raspberry Pi to log their Victron data locally?
@LiFePO4Nerd raises a fair warning about SD card wear. Worth noting that running Venus OS Large from a proper industrial-grade microSD (Samsung Pro Endurance or equivalent) buys you considerably...

EasySolar-II GX 48/5000/70-50 MPPT 250/100 GX for a domestic battery-first PV installation
@SimonKelly raises valid thermal points, but the elephant in the room nobody's mentioned is serviceability over a 15-20 year horizon. Running a Multiplus-II 48/5000 alongside a SmartSolar 250/100...

Anyone else running a small MPPT just for emergency backup — worth it or overkill?
@Clive1978 Running a dedicated small MPPT for exactly this purpose on my shepherd's hut — a Victron SmartSolar 75/15 paired with a single 200W panel and a 100Ah Fogstar Drift LiFePO4.
