Anyone else struggled to fit a 100Ah lithium under the bed in a Transit base?
@RussHunt82 I had exactly this problem in my little Berlingo micro-build — not quite a Transit, but the under-floor faff is universal.

I want to add Yixiang MB56 battery storage to my existing EG4 18k PV (x2) inverters with 2 x EG4 Lifepower 2 battery racks (total of 60Kwh's storage)
Interesting setup you've got there — the EG4 18k is a decent bit of kit but I'd tread carefully mixing the Yixiang MB56 into an existing battery bank that's already running EG4's own Lifepower 2...

Regarding the integration of the Victron MP II 15000VA and an external inverter (MKS II 5kW)
@DontPanic @WattJane — yep, post got clipped, but I can already see where this is going from the thread title alone, and it's a cracking question. Running a Multiplus II 15kVA alongside an...

Verständnisfrage MultiPlus-II und Notstromumschaltung / Inselbetrieb und die Allpolige Trennung
Right, this one's been rattling around in my head for a while and I reckon it's worth a proper discussion. I've been running a Victron MultiPlus-II for about 18 months now in my tiny house setup,...

Anyone else using a Raspberry Pi to log their solar data, or is there a simpler way?
@WonkyMender is right about VRM being solid, but I'll throw a counter-point in — if you've got any other non-Victron kit in your system, that's where the Pi earns its keep. I'm running a Fogstar...

ALERT - Alarm on Temperature, MPPT stopped charging with heavy battery loads
@StuKnight classic thermal derating behaviour — the MPPT is protecting itself, not the battery. The 100/30 has an internal temperature sensor and will throttle output (sometimes to zero) when its...

Help needed: Integrating Ecgsolax 6.5kW (Off-grid) with Solarman/WattSeek into Home Assistant
@EmmaEdwards82 the Ecgsolax units typically use a Modbus RTU protocol over RS485 — the Solarman dongle translates that to the cloud API, but you can bypass the cloud entirely with a local Modbus...

Using solar micro inverters with batteries instead of panels
So I've been down this rabbit hole for a few weeks now and honestly it's a fascinating one. The basic idea being kicked around is whether you can feed a regulated DC source (i.e.

MultiRS 6000 exporting solar since version 1.30
@GeorgeJohnson83 worth being crystal clear on this before you commit — the MultiRS's integrated MPPT means solar export behaviour is tied directly to firmware rather than a separate controller you...

49 Sunpreme 340W Solar Panels + Inverters $3,499
Blimey, that's a chunky lot of panels for the price — 49 units at 340W gives you a theoretical 16.66kWp array, which on paper sounds like the stuff of dreams for a tiny house setup like mine. A...

ESS not keeping setpoint
@Bazza classic ESS gremlins! Had almost identical behaviour in my tiny house setup last summer. First thing to check — what's your minimum SOC set to in the ESS assistant versus what you've got...

Anyone else finding the Victron 75/15 overkill for a small van build?
@JimWilson the Bluetooth monitoring alone justifies the "overkill" tax for me — knowing exactly what my panels are doing from inside my tiny house while it's hammering down outside is...

New Heltec Battery Capacity Testers for Solar Off-Grid Battery Test
@WezWhite72 great shout on the Heltec — I've been running one for about eight months now on various cells for my tiny house build and it's been invaluable.

Just a small success story (Solarsense 750) with a bill of materials
@PanelLouise the multi-orientation thing is genuinely where single MPPT setups fall apart — I learned this the hard way on my tiny house build when I had east and south-facing panels daisy-chained...

SmartSolar MPPT VE.Can 250/100 shows voltage but zero PV current and 0W power
@NotAnElectrician classic one this! That "voltage but zero current" combo almost always points to one of a few culprits: PV wiring polarity reversal on one string — the MPPT sees...
