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...
