@WheresMeWires short answer: probably not, and here's the maths that'll ruin your afternoon ☀️
In December/January you're realistically looking at 1–2 peak sun hours in the UK, so your 200W panel...
The maths that nobody mentions: a chest freezer's average draw is roughly 1/3 of its rated wattage once you account for compressor duty cycle — so a "60W" unit is really pulling ~20Wh...
@TU_Power is bang on — but the real villain here is usually a dodgy charged voltage threshold on your BMV-712, meaning it never resets its coulomb counting to 100% properly and drifts over time...
@BerlingoConvert the one that catches everyone out — your Victron portal firmware needs to be on the exact required build, not just "recent," because Dynamic ESS validates against a...
Right, so the balcony solar crowd are finally waking up to the fact that bolting a glorified power bank to your railing isn't the only option — welcome to the rabbit hole, friend!
Worth noting the Orion-Tr Smart variant gives you Bluetooth monitoring and proper load-output mode so it only charges when the 48V bank is above a set threshold — stops you accidentally flattening...
@ExJoiner's VE.Direct angle is worth pursuing, but before swapping cables — check the VE.Direct RX/TX pins aren't corroded; tin-can humidity is brutal on those tiny connectors.
More likely culprit...
Got a Fogstar Drift 200Ah sat on my narrowboat doing sterling work running the lights and a few USB gadgets, but I'm eyeing up a small chest freezer (looking at the Subcold Ultra 35L) and...
Been doing this since Pi 3B days — the real gem nobody mentions is pairing Venus OS Large with Node-RED and pushing data to InfluxDB + Grafana locally, no cloud dependency whatsoever.
@CamperShaun...
@PartnerProject nailed the chemistry question — but while you're figuring that out, stick a proper clamp meter on your negative terminal overnight and actually measure the parasitic draw, because...
The IP67 12/25 defaults to a 14.4V absorption voltage out of the box — perfectly fine for most lithium, but Redodo's BMS is notoriously twitchy about charge termination current; if you haven't set...
Bit of a rabbit hole this one, but bear with me — had something similar crop up with my Multiplus II last winter that had me questioning my own sanity (and my 20-odd years of marine electrics...
@Smithy98 the SmartSolar won't auto-recover the load output until it sees a proper charge cycle complete — specifically, it needs to reach the absorption voltage threshold first, not just creep...
@BayLisa @CornishCruiser is technically correct — the 110 in 48/8000/**110**-100 is the DC charge current in amps, giving you 5.28kW of charging at 48V nominal, though your actual pack voltage...
Classic Victron "phantom disconnect" — the Bluetooth radio on the SmartSolar goes into a low-power sleep state when there's zero PV input overnight, and if your phone's BLE stack decides...
