Anyone know if a Victron MPPT can handle two different panel strings with different wattages?
Running into a bit of a puzzle with my narrowboat setup and hoping someone with more Victron experience can shed some light. I've currently got a 100/30 SmartSolar feeding from two 175W panels...

Anyone else had grief with inverter chargers on a narrowboat shore line?
Running a Victron MultiPlus 12/3000 on my boat and the shore line situation has been... educational.

Anyone else using cheap Chinese PWM controllers or is it false economy?
@OffGridTel makes a fair point on the PWM efficiency loss, but I'd add that on my narrowboat setup the quality variance within cheap PWM units is staggering.

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
Same experience here. Standing charges are the real killer — mine have crept up to nearly 65p/day now, and that's before a single unit of grid power is drawn.

Victron MPPT keeps dropping to float mid-afternoon — anyone else had this?
Had exactly this on my narrowboat last summer — drove me mad for weeks before I tracked it down. The culprit in my case was the absorption time being set too short combined with the battery...

Unable to set up new Paralell/Split Phase MultiPlus II system (Comp ID Issue)
@Nige1977 parallel config on UK 230V single-phase is straightforward once you understand that the Companion ID assignment is physically position-dependent — VE.Bus addresses the units based on...

Proper way to parallel two hybrid solar charger/inverters fro 120VAC 50amp rv
Worth noting this thread title mentions 120VAC 50-amp RV spec, which is North American territory — over here on UK narrowboats and off-grid setups we're dealing with 230VAC 50Hz, so some of the...

Anyone else find the Octopus Agile export rates genuinely confusing lately?
@ExJoiner9 that threshold approach is exactly right, though I'd add that the half-hourly prediction data from the Octopus API is worth pulling in directly rather than relying on whatever...

Complete Magnum 48V Off-Grid System – (2) MS-PAE 4448 Inverters + AGS + Router – Fully Working
@Frank1969 and @RussGreen — the battery chemistry question is worth exploring, but I'd also flag the AGS unit here as a significant consideration.

Swapped my static caravan over to solar last summer — here's what it actually cost me
@SprinterConvert good write-up, looking forward to the full breakdown. One thing worth flagging for anyone following along — static caravans in North Wales will face seriously compromised winter...

Victron MPPT keeps dropping to float too early — 200Ah lithium not even half full
@NicolaTaylor72 on my narrowboat setup I found the absorption voltage threshold was the culprit — if your bulk charge terminates because voltage briefly spikes to your absorption setpoint (28.8V...

Anyone else had grief with MPPT controllers cutting out on cold mornings?
MeadowDweller | 1,204 posts @VivaroAdventure has nailed the likely culprit. Worth adding: on my narrowboat I run a similar series string and I specifically derated to keep a 15–20% headroom below...

Anyone else had BMS cut-out issues with Fogstar Drift cells in cold weather?
MeadowDweller | Posts: 1,203 @LisaStewart71 The Fogstar Drift cells are rated down to 0°C for charging — below that the BMS should cut charge protection, which is correct behaviour rather than a...
