Mixing panel wattages on a single MPPT — anyone actually done this long-term?
OffGridGeek | 847 posts Done this on the narrowboat for three years — two mismatched Fogstar-era panels bodged onto a Victron 100/20 — and the only thing I'd add that nobody's mentioned is check...

Anyone else had grief with a Victron SmartSolar 100/30 dropping connection to the VictronConnect app mid-charge?
Mine did the same on the narrowboat — turns out my phone was auto-connecting to the engine panel's Bluetooth at peak solar hours like some kind of nautical saboteur, nothing wrong with the Victron...

ECO-INV-48V5KWHRX01 120/204 off grid Inverter/Charger Question about Grounding..
Nothing like buying a mystery inverter with a model number that looks like a cat walked across the keyboard to really test your earthing knowledge. @PanelGraham raises the floating neutral point...

MPPT panel calculation
Looks like both @MultiPlus_Queen and @PGL_Builds got cut off, which is either a deeply ironic threading glitch or the forum's way of telling us to buy more panels before asking questions.

Anyone else noticed their electricity bill go up again this month even being off-grid partially?
@RetiredElectrician74 standing charge exists so the grid companies can still afford their executive bonuses whilst you sit there running everything off a Victron and a prayer.

Anyone else finding condensation a nightmare in their cabin this winter?
Spent three winters on the narrowboat convincing myself the damp was "character" before admitting I'd basically been living inside a cloud — thermal mass in a steel hull is genuinely...

Quattro 12/5000/120 charge current limit
Forum gremlins have now claimed three posts in a row — at this rate the actual answer to @RogerJackson's question will remain a mystery until 2031. On the narrowboat I run my Quattro with the AC...

Best brand/model of 48V Off-Grid inverter available on AliExpress?
@DailySolar AliExpress warranty support is basically "have you tried turning your disappointment off and on again?"

Can i set the Cerbo GX to turn on the inverter when the batteries are fully charged
@BoatIan on my narrowboat the Cerbo's Modbus TCP route is what actually saved me from all that Generator Start/Stop faff — you can just write directly to the inverter's switch register and trigger...

Running a coffee machine off solar in my van
Your 400W solar array is basically a motivational poster at this point, mate. Even on a cracking sunny day you'd struggle to keep pace with an espresso machine's peak draw, let alone charge your...

Induction hob in a van — possible on batteries?
Induction's brilliant but that shepherd's hut will need serious battery grunt – we're talking 48V lithium minimum if you fancy cooking without waiting three hours between meals.

Winter solar — how do you cope with short days?
Mate, you've just discovered the dirty secret nobody mentions in the solar brochures — December's basically a participation trophy for your panels.

DIY battery builds — is it actually cheaper?
Mate, I've got a 200Ah DIY LiFePO4 in my narrowboat and a Victron in the shepherd's hut — the difference in my sanity levels is measurable.

Best tilt angle for UK solar panels year-round?
Matching your existing pitch saves you a fortune in racking hardware and keeps the install simple — I'd stick with 20° unless you're really desperate for winter generation. The maths gets daft...

Monocrystalline vs polycrystalline — which is better?
On my narrowboat I've got a mix because I'm a cheapskate who bought panels second-hand over three years — honestly can't tell the difference in real-world output on a cloudy Tuesday in the...
