Had something very similar with my Orion 30A last winter. Mine was cutting out after about 45 minutes on the motorway, which was baffling because short runs were absolutely fine.
Turned out to be...
Been running a Pi 4 for about eight months now logging data from my Victron SmartShunt via the VE.Direct interface.
@WattSue exactly the same boat here — I've got a 24V main bank and need to keep a 12V auxiliary topped up for my emergency backup loads (comms gear mainly).
What I've been trying to figure out is...
Been dealing with exactly this since October and it's properly doing my head in.
My setup is a 100Ah Fogstar Drift under the bed, fed by a 40A DC-DC charger from the alternator.
Been having a similar head-scratch with my setup and wondering if others have hit the same wall.
Running a Victron SmartSolar 100/30 and recently swapped out my old AGM bank for a pair of Fogstar...
@SueJohnson what's your actual open-circuit voltage from the panels? That's the critical figure. The 100V limit on that Victron controller is an absolute maximum — not a "try not to...
Not sure if this applies to your specific situation @Spider, but worth flagging — the 250/100 refers to max open-circuit voltage (250V) and max charge current (100A).
@BrookRunner makes a fair point about lead-acid origins, but I'm curious about a specific scenario that hasn't been covered yet — what happens during engine start when the alternator is cold and...
Been putting together a basic emergency backup setup at home after last year's power cuts. Nothing fancy, just want to keep the router, a few lights and phone charging going if the grid goes down...
Been looking at doing something similar for emergency backup on my static — mainly want to make sure I can keep essentials running if the mains drops out unexpectedly.
Quick question for anyone...
I've got a small cabin in Wales that currently runs off mains, but power cuts are getting more frequent and I'm after a basic emergency backup setup rather than full off-grid.
@Julie1972 one thing nobody's mentioned yet — have you got a GX device or a Raspberry Pi running VenusOS anywhere on the network?

Had a similar nightmare last year when I set up my emergency backup for the house. What sorted it for me was fitting a hard-start kit on the compressor — made a massive difference to the inrush...
