DIY 12 Volt setup camping, overlanding setup. Victron 250w Inverter, too small or big enough? 

Nice review. I have victron system aswell but 1 important think for you. Your electric bike charger is 42V * 4,5 A = 189 watt. Plus other stuff and you said that around 265 wats is going from your 12 V 250 VA victron. But it is not 250 wat inverter, it is only marking which use victron, marketing stuff ! - You did not red Victron product spec sheet correctly. Victron 12 /250 is made for optimal use : 25°C/40°C: 200W/175W and max is 400 wats. So for long term usage you are not in range of 200 wats. Yes , now your 12 / 250 victron works, but for how long when you make him work above recomended wattage? If 400 watt is considered as 100% then 265 wats is 66,25 % You shoul rather change it to 12 / 375 victron type ( maybe 20 bucks more) which is made for this range 25°C/40°C: 300/260W and max is 700 wats. If 700 watt is considered as 100% then 265 wats is 37,85 % Put yourself a question. Is is better to run "engine" which uses everyday 66,25 % or only 37,85 % of its maximum power . Which one will last longer ? All depends what powerdraw you want to use. Cheers.

Most don't need the 170kW from the donk in their 4x4 either...but there you go. I like your "just enough" approach...smart. Less cost, smaller cables. I reckon everyone underestimates the amount of solar they install. Most days are not perfect solar weather, but they size their system on the maximum power their PV('s) claim to deliver which only occurs on a perfect sunny day with cool (25oC) panels.

I have the exact same inverter with an 80ah battery and an 80L engel fridge and 200w blanket. Like you plenty. I only got the inverter because I bought a starlìnk.

For the last two years I've running my entire house Off-grid for 99% of the time on the 24Volt-250Va Victron (200+Watts). Runs on 24v Leadacid batteries, powers the Dishy (Starlink) for the last year whenever at home (30Watt consume in Sleep mode, 120watt for a short while when getting out of sleep mode, and about 50 to 60 watt Consume during use) The Victron still has plenty of Juice left for more equipment. Like a 120Watt (actual use 90Watts non-stop) Battery charger to boost the 12V Light batteries. Or one or two laptops at the same time All in all I'm surprised how well you can run a Off-grid house in the winter with just this little inverter (just using it for Charging phones and Laptops, Internet, Music, etc. ) For the Vacuum cleaning I've a 3.000Watt German Brand Inverter, and only use it for certain short terms. The only Downside of this 250 Victron, it doesn't support my Makita battery charger.. consumes 260 Watt and it turns of during start-up

That's great, experimenting with the inverter. Looks like the sun went down for 10 minutes in the middle of the video though!!!

Victron doesn't sell equipment in watts, they use volt-amps (VA). So this 250va inverter is actually rated for around 175 to 200 watts. Kinda annoying.

Thanks Darryl 👍

I run a 350w Dometic pure sine inverter in my truck never needed anything bigger it cost me about $109 from memory, I use it touring to charge my gear and it'll also charge my Makita batteries when at work so no more looking for spare gpo's on job sites or in clients houses, and haven't lost/forgot a charger since because it never leaves the canopy..
