Anyone else looked into these smart switcher setups? I'm genuinely curious whether they're actually worth the outlay compared to a traditional battery bank.
I've been running a small 5kWh LiFePO4 system in my shepherds hut for about 18 months now, and it's been solid. But I'm wondering if I've been overthinking it. The appeal of a no-battery system with intelligent switching between grid, solar, and a backup generator is obvious on paper — lower upfront cost, no battery management headaches.
What's got me puzzled though:
How do you actually handle cloud cover and evening usage without storage? Do these systems just flip you back to grid automatically? Seems like you'd need a pretty responsive switchover to avoid brownouts. Has anyone got real-world experience with how snappy these are?
And the generator side — are people actually happy with relying on genset capacity for cloudy days? I imagine running a petrol gen every time the sun dips behind clouds gets old quickly, plus the fuel costs.
I'm particularly interested in setups using Victron or similar inverters with this approach. Are they managing loads properly during transitions?
The shepherds hut's been a good testbed for me, but I'm planning a tiny house build next year and wanted to reconsider everything before going bigger. Might be tempting to skip the batteries if it actually works reliably.
Anyone running no-battery pure sine wave systems day-to-day? What's your actual experience been?
