Walk a little faster with my lighter wallet.You went from a 150v Victron to a 250v Growatt. Imagine what you could do with a 250v Victron

iPhone is loosely based on Unix.
Who uses unix?
And iPhone gives you zero access to the Unix architecture
I'd just like to interject for a moment. What you're referring to as macOS, is in fact, Darwin/macOS, or as I've recently taken to calling it, Darwin plus macOS. macOS is not an operating system unto itself, but rather another proprietary component of a fully functioning Darwin system made useful by the Darwin corelibs, shell utilities, and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the Darwin system every day, without realizing it. Through a peculiar turn of events, the version of Darwin that is widely used today is often called macOS, and many of its users are not aware that it is basically the Darwin system, developed by Apple Inc.
There really is a Darwin, and these people are using it, but it is just a part of the system they use. Darwin is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Darwin is normally used in combination with the macOS operating system: the whole system is basically Darwin with macOS added, or Darwin/macOS. All the so-called macOS versions are really versions of Darwin/macOS!
The logical end game for the Victron ecosystem seems to be a minimum of two 450/100 (for redundancy). Isolation of the PV array and a bunch of additional features that the 250s don't have, for not a lot more. Actual voltage limit being 8*battery float voltage I believe and 18A per tracker with the 450/100s having two strings each?At least a year before I discovered this forum, I was aggressively making my own mistakes. Mistake #1: 141Voc vs. 150Voc max on a MPPT 150/100. I only had a single 3S string with 5 more strings in the container as that's all I needed to keep things online.
Fortunately, my panels are at the lower end of the ±3% variation in Voc rating, and I rarely get over low 130s in STC conditions.
Then I finally found the reference in the manual from four years ago that explicitly stated 2S 72 cell panels and 3S 60 cell panels on a 150V controller. Fortunately, I discovered this before it got too cold.
Solution? Rewire the panels to 2S? Hell no. That would have been 9P and would have blown the 70A PV input current limit. Pay the stupid tax and upgrade to a 250/100, swap it out and sell the 150/100 at a discount to some fortunate soul.

Darwin may have been developed by Apple, but they acquired the core of it from NeXT computer, which ran on the Mach microkernel, which was developed by CMU and DARPA, with a POSIX layer largely based on BSD Unix, which, of course, was developed at Berkley, based on the original Unix, which was brought to us by the one and only Ma Bell!curiouscarbon said:I'd just like to interject for a moment.

“ Should have” ……everyone knows if you do somthing wrong , the manufacturerYour expectations of “should” seems to be the outlier in everything I’ve seeing in specification and data sheets.
Why have a spec if it’s meaningless?
Either was sounds like your grow watts are suiting you’re needs, glad you’re happy.
“ Should have” ……everyone knows if you do somthing wrong , the manufacturer
“should have” known in advance and prevented it…that why they invented crystal balls eons ago.
Well , since yer gonna take a shot , Yep.. it’s called live and learn..become better.. don’t depend on others to think for ya ….take responsibility for actions or inaction. . Nanny state thinking will be a great selling point in the coming years…run for office… you will probably win …?(Note: Must be read in a Dana Carvey voice)
I don't know what the world is coming to these days! Back when I was a kid we didn't have to wear seatbelts! If we did, all they were good for was to keep us from flying through the windshield so our head could hit the metal dashboard! If you dropped a toaster in the bathtub, you know it! Now you probably just have to go outside and reset your ground fault GFCI interrupter thingy. When I was a kid, the Christmas tree bulbs were big and glass, and you learned the hard way to unplug them before you stuck your finger in them to twist them out! And we liked it!

Yeah can't imagine them throwing in a Voltronics or other Chinese screamer in something that's outfitted like a yacht. No doubt many of the prospective owners of this 200k+ sprinter van conversion also have Victron gear in their boat(s)."The Roadtrip packs a Victron electrical system with 110-Ah AGM battery or available lithium upgrade"
Sprinter Van conversion from Europe starts at $200,000
European "yacht on wheels" camper van journeys onto American market
The world keeps getting brighter for Americans lusting after European camper vans with no recent history of US availability. Westfalia is officially on its way back to market, Volkswagen will soon have an all-electric van canvas with which converters can work, and now Las Vegas' Caleche Customs is…newatlas.com
Haaa. The level of scrutiny big boat owners have to endure when rigging their boats is insane.Yeah can't imagine them throwing in a Voltronics or other Chinese screamer in something that's outfitted like a yacht.

you can get a lower powered EVSE they go down to 6 AMPThe EV is going to be a PITA. Like an electric range on high it just sucks it down without stopping This is from the 30th:
View attachment 165579
I'm tracking HVAC, EV, and HWH/Dryer along with totals, all roll-my own sensors and software. I bought an EV switch to limit demand for my electric HWH and Clothes dryer to only one of the two. You might find one of these boxes useful for limiting demand, but if you are grid tied, it really doesn't matter as much. I'm controlling the EV outlet by a RS-485 relay board and an SBC, a simple HWH timer could do something similar. Frankly if your primary concern is payback time, and you are just going to grid tie, the micro-inverters are the way to go, but once you add batteries it gets more complicated. The newer AIO's actually simplify this as well, and allow for much higher string voltages.
It kind of depends on how much you want to dink around with it. The problem with component systems of any kind is they tend to cost significantly more, but they do give you the ability to scale and replace functionality independently. Once the cost of an integrated system is low enough the management cost of components begins to dwarf the scaling benefit. Integrated systems tend to improve more rapidly as engineering designs take advantage of the close coupling of the components, and the ability to optimize both production and capability around a known stable set of hardware. I can assure you that over the long term, seperate MPPT's, Inverters, and the like will be relegated to edge case products, where an AIO just won't work.
On the battery front, a lot of folks are saving real coin by rolling their own BMS systems on free-standing cells. I think this too will eventually become less and less prevalent as batteries with integrated BMS systems become more plug and play, and the prices drop to the point rolling your own really doesn't save money. In particular if we actually see some of the new battery tech actually come to fruition, expect to see BMS control via CAN bus to become increasingly standardized, and just built-in. Right now the cost of batteries in general and a desire not to have to replace them every year will make this transition much longer than the AIO side.
Whatever your path enjoy the travel!
I'm about to install an EVSE with OCPP, connected to the ChargeHQ service and it will moderate the power flowing into the EV based on how much excess solar PV is available. My EV will accept power in 1 A increments anywhere from 6 A (~1.4 kW) to 28 A (~6.6 kW).you can get a lower powered EVSE they go down to 6 AMP
