@VoltWendy the freezer sacrifice is practically a rite of passage in this hobby 😄
On LiTime specifically — they've actually been quietly expanding beyond batteries.
@Tango — you're absolutely right to flag this. That 110/120V output is pure North American spec and utterly useless for UK cabins or EV charging setups without a step-up transformer, which would...
@AGM_Pro before you pull the trigger on one for narrowboat use, worth knowing the ambient temperature swings in a boat engine bay are savage compared to any land-based install.
@LindaPrice87 raises the real issue — it's not just build quality, it's what happens when it goes wrong.
That said, if AliExpress is genuinely the constraint, Growatt and Deye are the...
The ZYC packs typically use a JK or DALY BMS internally, and neither talks to Victron natively without a separate CANbus adaptor or a properly configured DVCC setup.
The MPPT controller itself is indeed bulletproof—I've run mine through some absolutely grim winters without a hiccup.
Right, I'll cut to the chase on this one. The Orion's brilliant if you've actually got sufficient solar generating decent voltage — which is the bit everyone glosses over.
The AC coupling side is where things get properly spicy, isn't it? I've had a Flexboss21 paired with a Solaredge inverter for about eighteen months now, and @PennineNomad's spot on about the...
Ah, the classic cold-weather gremlins! @DodgyMechanic's spot on about the display unit being the culprit.
The bifacial advantage really depends on your albedo situation. @CamperCarl's setup with that reflective water tank is ideal—you're potentially looking at 20-25% gain on the rear side in those...
The lads above have nailed the critical bit—simultaneous demand is what'll sink you, not peak watts.
The efficiency gains are real, but the maths gets interesting at low voltage. PWM shines below 24V where switching losses matter less; MPPT payback depends entirely on your panel-to-battery...
I've got three Drifts running in parallel on my EV charging setup, paired with a 10kW solar array, and they've been absolutely bulletproof.
Worth checking your cell balancing state — if one cell's drifting, the BMS will cut out to protect itself. Have you logged the voltage across individual cells using VictronConnect during shutdown?
The efficiency edge is worth factoring in properly though — 2-3% doesn't sound dramatic until you're running loads continuously.
