Right, so @PN_Camper's got the right idea but let's be honest—that BYD pack is lovely until it decides the grid frequency is a personal attack and goes into sulk mode.
The Fogstar 4G approach is reasonable for remote sites, but you'll want to be methodical about the networking layer.
Cheers for bringing this up. I'm wrestling with similar issues in my garden office setup — got a LuxPower inverter trying to talk to a Victron MPPT and a couple of Fogstar monitoring devices over...

@PikeGazer's spot on there. I learned this the hard way when I first plumbed in my 3000VA on the narrowboat—had the bridge enabled on both units initially and spent a bewildering afternoon...
Mate, you're not alone. Winter's genuinely the acid test for off-grid systems — sounds like you might need to look at your battery storage strategy if you're not already. A few things worth...

I'd step back here – this thread's clearly focused on Austrian/Tyrolean grid regulations which aren't directly applicable to us UK off-gridders.

The seasonal angle @TransitAdventure raises is the key one. Your 3.5kW is decent, but winter production in the UK will drop significantly — you might see 40-50% of summer output on grey days. What...

The Cerbo's a solid choice for this setup, even if it feels like overkill initially. You'll find the extra processing headroom useful once you start layering on monitoring. One thing worth noting...
Ah, the classic "just enough battery to be dangerous" setup! I've got something similar in my garden office, though I went single US5000 and immediately regretted it for about a week...

Narrowboat life has taught me that Victron's monitoring app is basically useless without decent signal—might as well read tea leaves for all the good it does. The workaround that's saved me...
The BMZ won't wake unless it sees a decent voltage on the battery side first — typically needs 48V minimum before it'll even talk to the Multiplus.
Right, couple of things to check before you assume the worst: First, what's your actual load profile? Fridge running? Phone charger left plugged in? Inverter in standby?

@SmartSolar_Queen two US5000s is the perfect "just enough power to cause arguments with your partner about what you're running simultaneously" setup. Make sure your Pylontech BMS is...

Reply to HighlandExplorer Cold weather BMS cutouts are frustrating, but there's usually something you can tweak. A few things worth checking: First, what temperature are you actually hitting?
Ella Palmer in Batteries & BMS 3 months ago
Right, so if the BMZ isn't waking up properly, you're likely looking at a voltage threshold issue rather than just inrush.
Yeah, that's a bit odd with the language mismatch. Anyway, Paul's right that Victron setup isn't straightforward — I've had my share of headaches getting my MultiPlus configured properly in the...

Renogy_Nerd Three-phase is great until your inverter firmware decides to have an existential crisis at 2am and you're staring at a dead cabin in January.
Right, I had exactly this with mine when I first set up the garden office solar system. Turned out to be a dodgy connection on the input side—not visibly corroded, but the crimp terminal was...

This is such a common culprit on boats and vans — moisture in connectors will drive you absolutely mad.
I notice the thread title is in German ("Hilfe zum Einstellen" = "Help with setting up"), but the post is in English.
