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

Can pull up next to Tesla charger and put awning out and pretend you are guy repairing them while you're actually just there stealing KW's to replenish your own batteries. :)
End game is when you pull up with timselectric's 40' blue container with a MWh of storage. Unless upnorth beats him to it as a massive tax write off.
 
Another good thread ruined because so many of you self centered narcissist can't stay on the FU**ING topic.

Yea, It pisses me off. Several times I've started to start a thread here but haven't because of this crap.
Sir/Ma’am, could you kindly remove this post. It is not on the topic of Victron, euros, or trash
 
I assume this is a catchall victron thread at this point?

I have a few questions for resident victron enthusiasts and experts:

1. Cerbo S gx vs regular cerbo gx: Will the S model work to communicate with/monitor a bms? What is needed to accomplish that? I don't need tank sensors and such that come on the more expensive cerbo and would like to save some money. Any reason to get the regular cerbo gx for small/medium off grid installation?

2. If I install a Multiplus II and want to use a generator for battery charging/loads during days with no sun what is better: using the multiplus/victron ecosystem for generator control OR using an EG4 chargeverter?

3. What are the pros and cons of using an autotransformer vs using two multipluses to get 120/240v?

Thank you
to get back on topic.... can anyone answer number 2 or 3? thanks for answers to number 1

From my understanding Victron inverters are designed to handle power from generators. They’re primarily designed for mobile installations which have a high probability of using generator power.

While you can use either, why spend more money if you don’t have to?

2. My quattros gobble up the shitty power my Harbor Freight generator produces... like candy. num, num, num, num, num! The reason the chargeverter exists is because of shitty Chinese voltronics-type inverter/chargers (MPP Solar, Growatt, EG4, etc.) that must have extremely clean power UNLIKE all tier-1 products (Victron, Magnum, Outback, Midnite, Schneider, etc.).

3. Mostly preference. Though worth noting the AT has a limitation of 28A max imbalance even on the 100A model, i.e., power use between L1-N and L2-N can never be more than 3360W continuous.

I chose two primarily for redundancy. If I only have one inverter, and it goes out, I'm making other arrangements. Yes, loss of one quattro will shut everything down, but I can reconfigure the second unit as single phase and jumper L1 to L2 getting 120V on each leg, 0V between.
 
Victron inverter/chargers pass generator power through to your loads is that correct? So you are feeding shitty power to your loads? or have you programmed your system to only charge battery from the generator?

Thanks again, all good data for my cost comparison spreadsheet.

Do you have an MPP? or other Voltronic?
I do,
The MPP's charge perfectly from my cheap "Champion" generator - complete with handles and wheels no less.
The reason for the Chargeverter is to allow charging and inverting at the same time. Something Cheap Voltronics inverters Can't actually do.

I've ran my noisy generac through my SGP (Voltronic) and SRNE so much the rubber vibration pads fell off but the handle and wheels work great.

I wish they could, but some are cheap enough you could dedicate them as a charger.

I'll still likely own more than a Victron MPPT someday.

Yeah, all the Victron talk makes me want to buy a van just to do a Victron build! See if I can "pimp it out" like the rest of the builds I have been watching!

Yes. When I do so, our electric blanket won't work. The timer function apparently relies on a stable 60Hz, and the 58-62Hz the Predator puts out means the blanket refuses to turn on.

or have you programmed your system to only charge battery from the generator?

This isn't possible.

I have a PowMr (SNRE clone, SNRE uses a modified Voltronics design), but I've never run it on generator.

You're very fortunate. Either you have uncommonly tolerant Voltronics units, or you have a generator with very low THD, or you're not powering significant loads via passthrough.

When all the manufacturers and distributors are recommending inverter generators, that says something.

The reason for the Chargeverter is to allow charging and inverting at the same time.

While it allows that, Nah. It's because of the many many many complaints about being unable to charge with a non-inverter generator.

Something Cheap Voltronics inverters Can't actually do.

No inverter/charger can, including my Quattros. Inverter/chargers are either inverters or chargers, never both at the same time. They essentially use the same circuitry in reverse to charge. They are either passing through the generator power, passing through + charging or inverting.

If MPP Solar, Growatt, EG4, etc., reliably and consistently charged from low end non-inverter generators, the Chargeverter likely wouldn't exist.

Don't get me wrong. I think they're awesome... I want one. I mean who doesn't want a 100A 48V charger for ~$400???!!!! I simply don't need it.

I don't do anything special - I set the charging amps to 75% of the rated generator capacity - that is it.
I would like to have a Chargeverter - to be able to charge and invert at the same time, but the darn things are Far to Popular!
 
Got the Friday shakes for more blue. Ordered a second 150/35 the little fella was getting lonely.
Yo, listen up here's a story
About a little guy
That lives in a blue world
And all day and all night
And everything he sees is just blue
Like him inside and outside
Blue his inverter
With a blue little controller
And a blue system
And everything is blue for him
And himself and everybody around
Cause he ain't got nobody to listen to
