Victron is Over-priced Eurotrash. Why would anybody buy Victron over an AiO?

Those are both step down converters. I'm already planning to use the 30 amp version to provide 12 volt power to the trailer's 12 volt system.
The step up (boost) 12->48 converter is what I would like to see Victron add to their product line.
Yeah but, as I said, same panel power handling if I am doing the math correctly
. Especially nice at that price point.
For me it allowed higher voltage headroom for those crisp, cold winter days with the strings I use.

Ah ok I was confused because the 250/60 has a charge limit of 3420W versus a /100 with 5700W (assuming 57V charge). But if that meets your needs it's all goodYeah but, as I said, same panel power handling if I am doing the math correctly

Pulled the trigger on a Quattro 48/3000. Was trying to decide between that and the cheaper mp2 3kVA UL listed. My thinking was the Quattro may be quieter running than the mp2, plus who doesn't like a second ac input. In my case I can accept the increased idle consumption over the mp2. JB tools had 10% off on Amazon for this model and apparently there is a support solution for Victron gear sold by them:
You are correct, it clips the excess power if produced so simple math doesn’t work here
. It just can handle the overpanelling for marginal conditions but doesn’t help production under optimal conditions.

No shame in optimizing for the winter days. Maximizes value of your SCC.You are correct, it clips the excess power if produced so simple math doesn’t work here

I regret to inform the group I just ordered my 4th piece of victron junk - I am sure there will be whining and complaining except for the Pappa smurf freak....
Now I have the shunt, a phoenix, and a 250/100.... and I just ordered a 150/35 ... I appologize to the group in advance of the arrival of the new addition to my family.
This is PROOF they multiple given time.

LOL It's difficult once you start; I was shocked at how undersized the victron shunt was compared to the four batriums 1000/500 amp shunts I'm removing. I only paid $27.49 more for the Victor Shunt than the batrium, and I thought I did not get my money's worth. /j

Victron does sell a larger shunt. Either in the Lynx or the SmartShunt.

Yeah kromc5 is just joking there with the /j, the tiny ones in his pictures are the Batrium's, the big boys are the 2000A smartshunts.

I have the 500A shunt. Not sure why Victron chose to use 3/8" bolts on the 500A shunt (I assume its because they figure people are using batteries with 100A and 200A BMSs, with 4-0ga wire), I had been using 5/16" everywhere else. Had to go to O'Rielly's to get some 4/6ga copper 3/8" lugs and mate them to 8ga wire (my crimper is the one you use a hammer on to get a positive crimp)

I don't know what kind of crimp you'll get putting 8awg into a 4awg lug.
I would highly recommend selterm lugs of the appropriate size.

The crimp is actually very good, because this is the crimper I bought https://www.amazon.com/dp/B00E1UUVT0
I prefer the a hydraulic crimper over the impact ones. We tested two hydraulic crimpers against the shops hammer ones using a purely red neck too many beers on a weekend get together. Results were surprising.
Now this isn't an electrical test as much as a pull strength test but it was interesting.
1. Gather a bunch of very bored people on a summer afternoon.
2. Beer, it really does help with coming up with wild ideas.
3. A tractor. 1 and 2 probably shouldn't involve step 3 but it did.
4. A spool of braided 2/0 cable. I think was steel but I don't remember. See #2.
5. A box full of cable ends.
6. 2 new hydraulic crimpers and old timers making fun of the purchase. See #2 to get idea how this escalated so fast.
7. Hammer crimpers and normal hammers plus (see #2 for where this next idea came from) 10 lbs and 20 lbs sledge hammers.
Ok two pickup trucks were parked facing away from each other.
The tractor was parked in line with the middle of the two trucks.
Like this :
(truck A) (truck B)
........(Tractor)
One end of the cable got a connector put on it with the hydraulic crimper.
The other end was done with the hammer type.
Each end of the cable was attached to the trailer hitch of a truck.
The tractor's backhoe boom would snag the middle of the cable and pull. Which ever end let go was the loser.
This went on for 2 hours with the hammer fans using regular hammers and then a 10 lb hammer.
The hammer connector guys were losing back to back. They didn't take this to well. (see #2)
Some idiot found the #20 hammer that was for working on the dozer. In his mind it was going to make the cable ends stay on better. Not sure on the logic here since the other ones were flatting out just fine in my opinion.
We weren't paying much attention to him and just thought the extra hammer strikes were his attempts at making sure the ends were on there good up till we started getting pelted with metal fragments.
The drunk fool had hammered one of the impact crimpers into the concrete floor slab of the shop and the other one he shattered into a million pieces which was the bits that were raining down on us.
Anyways from the results of this scientific endeavor we came to the conclusion hydraulic crimpers make better ends

I don't like them because they can damage the strands of the wire. I would bet where they went wrong, other than not enough beer, was the harder they hit the worse the damage.

You gotta think a hydraulic crimper is pushing in symetrically from all sides, versus a hammer just making a dimple.I prefer the a hydraulic crimper over the impact ones.

When I built my system, I did the usual and bought one from Amazon, but then realised it didn't do 120mm cable, so found a bargain on eBay.
Only problem is I can hardly lift it, best bet put it in a vice, its certainly not single handed use!
They both do good crimps, but the top one you have to do multiple times, the bottom one, just the once, maybe twice if its a long lug.
Top one does up to 70mm cable, the bottom one is a Cembre hydraulic crimping tool HT131C and does up to 400mm2 cable.
Crimping force: 130kN (14.6sh ton)
Rated operating pressure: 700 bar (10,000 psi)

Of course, I would'nt have bought it otherwise
Alright blue brain trust,
Is this PV trend with periodic dips normal?
Sure there were some clouds in the area as you can see the large sustained dip in production. Is this just MPPT routinely sweep? I just don’t remember seeing this when I initially set the system up.
This is just two 170w panels in series.

I bet if you look it will be exactly 10 minute intervals, it's just the MPPT doing it's thing, sometimes it will show very clearly, other days you won't see it.

Yes. Sometimes you see them, sometimes not.
When the data sampling gets thinned out to once per
I’m still not clear on VictronConnect what the retention rate of the data is.
Edit: It looks like you get the last two minutes of data points in 1 second intervals.
Everything prior to that is one data point every 30 seconds.
