    Victron MultiPlus Compact 24/2000/50 Continuous Load

    Yes, the Compact has fundamentally the exact same functionality as the full-size Multi or, for that matter, the Quattro line as well... so, yes, the dongle works the same, the VE.Bus communication/control works the same, etc... but unfortunately, unless the 3rd-party BMS is communicating over...

    Problem with Victron Battery Protect

    No. As noted above: do not do this. Your Battery Protect will fail, and it will not be covered by the warranty because you're using it in an expressly forbidden configuration.

    Problem with Victron Battery Protect

    All: Please note the description, in which he specifically says "do not use a battery protect with an inverter". The video was made before everyone understood how the Battery Protects work and why they fail using them this way.

    Confused? Battery+solar+Mppt+shore power+ generator+ inverter.

    Certainly every one that I'm aware of does... though this is where some people get confused by why they also need an external ATS or manual source selector if they have multiple AC sources, such as a generator and shore power; the internal transfer switch of most inverter/chargers is for...

    What low voltage disconnect?

    What low voltage disconnect?

    Dude... I hate Sterling manuals and product descriptions SO MUCH. They're almost all written by Charles Sterling Sr. and he spends half the manual talking about why you need the thing that you clearly probably already have because you're obviously reading the manual for it :rolleyes: . And their...

    What low voltage disconnect?

    LOL! No worries at all, sometimes you gotta ask the question first to find out what other information you need to give! If you're only disconnecting DC loads, then the Battery Protect is actually perfectly appropriate for you - that's what it's designed for. It can't be used to disconnect an...

    5280W solar max for the Mppt charger. can i exceed?

    Ahhhhhh I see that you're creatively editing your answers to look less foolish. Well, 100A at 15v won't do you any good either... which you'd also know if you understood how an MPPT works. Okay. I'm out of this conversation, that's about all the nonsense I can take. ?

    5280W solar max for the Mppt charger. can i exceed?

    Sooooo if you can get your full 100A charge current to your batteries from 7A input at high voltage from your array, for the third time: why in god's name would you try to put 100A into the MPPT?? You're literally not gaining anything, and you're just shedding godawful amounts of energy as heat...

    5280W solar max for the Mppt charger. can i exceed?

    Wow... you really have no idea how an MPPT works? I explained this before. You don't need to put 100A IN to get 100A OUT, because in your own words, voltage matters. 7A @200vDC IN = ~103.70A OUT @13.5vDC

    5280W solar max for the Mppt charger. can i exceed?

    Max Isc is max Isc. Why is this so difficult? And I still want to know why you would ever try to put that much current into an SCC, that's a horrifyingly inefficient use of your panels.

    5280W solar max for the Mppt charger. can i exceed?

    Dude, LOL I'm literally the #6 Victron Product Expert in the world... yes, I'm quite familiar with the warranty. And the spec sheet, where it states a maximum Isc input current, and footnote 2 that says a higher Isc input current may damage the controller, and also Article 3 ss2 of the Victron...

    5280W solar max for the Mppt charger. can i exceed?

    Wow, what is going on in this thread... What the hell, I'll climb in: A 100A SCC is rated for output current at battery voltage, not input current at panel voltage. Just because it can output 100A to a battery at 13.5 or 14.4 doesn't mean that it can take 100A input at 75 or 100 or 150v, and it...

    Used Valence u27-12xp

    In at least several of Will's YouTube videos he actually has the Valence RT series, which do have an onboard BMS and are truly drop-ins; the XP series that you reference does not have an onboard BMS, so is not a drop-in LFP battery. There are lots of ways, using 3rd-party hardware, to "emulate"...

    What low voltage disconnect?

    Will is correct, for reasons which are long and technical and covered in several different threads here. Now, to answer your question, we'll need more data: What are you disconnecting? Does the disconnect device need to be bistable (ie, are you running charge sources through it as well, or only...

    Invertor problem

    Oh man... Well, my apologies for (though now I have to go look) not getting to that thread on your initial question... Victron's Battery Protect is, hands down, the single most commonly misunderstood and misused component they manufacture, so don't feel bad about it... We caught it in time. In...

    Invertor problem

    @Heliman65, this may or may not be the cause of the problem, but please immediately remove your Battery Protect from this setup - it is expressly forbidden to use the Victron Battery Protect to directly interrupt the main DC supply line of an inverter; it is furthermore expressly forbidden to...

    AC-DC Lifepo4 charger reccomendation?

    Hi Kish, The "recondition" voltage will be inapplicable for an LFP bank, as reconditioning must be turned off entirely -reconditioning is for Pb batteries only, and is effectively a deliberate overcharging of a lead battery to burn off sulfation, which is not applicable to LFP batteries...

    LIFEPO4 battery prices rising/stuck?

    As a Victron LFP and Battle Born distributor, I can certainly attest that the tariffs caused multiple price increases last year - Battle Born raised our prices twice in the last quarter of '19, though they encouraged us and all their distributors to hold our retail pricing steady regardless...

    Where is the cover?

    Haha true, just screw the whole thing down, poke some holes in the sides of the packaging, you're good to go :LOL:
  24. Justin Laureltec

    Where is the cover?

    Yyyyup, no cover in there... in retail packaging, the original item will have the cover installed. That listing is sold and shipped by Amazon, so most likely what happened is someone else ordered it, removed the cover (whether deliberately or accidentally) and returned it, and Amazon people have...

    AC-DC Lifepo4 charger reccomendation?

    Even better, coming soon (as in, within the next couple of weeks) to VictronConnect: FW update for the IP67 and IP65 chargers that allows an incredible amount of control over the exact charge profile and behavior of the chargers. The screenshots below are from my IP65 charger that's managing my...

    AC-DC Lifepo4 charger reccomendation?

    Hmmmm I suppose it depends on one's definition of "affordable", really - that's why I didn't initially respond, because most of the chargers I could point to are, well, not cheap. At the 40-50A range directly, I could suggest the Sterling ProCharge Ultra (PCU) 1240 or the PCU 1250... that being...

    Solar DIY help

    @xaratemplate, there's a lot that I cannot offer you, because we only distribute Tier-1 components and therefore our inverters (strictly Victron) in particular will be unfortunately out of your budget; I wish I could say otherwise, but it's the price of only distributing products that we have...

    Setting up outback SCC for lead acid batteries

    Personally I wouldn't be worried about it - 60A into a 232Ah bank is still only just over .25C, which is perfectly acceptable by any Pb manufacturers I'm aware of - in fact perfectly acceptable for LFP as well. I think you're good.

    Valence Lithium Batteries

    That video is a bit misleading, as that battery is the RT version, which is a drop-in, not the XP version that the OP is inquiring about.

    Valence Lithium Batteries

    They're not drop-ins, thus their pricing. No BMS, though they do have internal cell monitoring and -when connected to a laptop running their software or to the external U-BMS that consumers can't buy- cell balancing as well, but they're very specifically NOT drop-in replacements. Lots of...

    Can anyone help with wire sizing

    @Whome, where did you purchase your Victron equipment? All authorized Victron distributors are strictly required by Victron to provide technical support for the components they sell - technically this is only for the Victron equipment, but that is generally interpreted to also mean advising on...

    Bussman Series 187 or 285 (the breaker posted is a chinese knockoff of a Series 285) go to 200A and 48vDC. Worth noting that "Blue Sea" Series 187 and 285 breakers are just the Bussman breakers in a Blue Sea retail package. I strongly second @tictag's comments: never trust the knockoff...

    Trying to destory my SCC's: I can't do it!

    Can confirm that they don't actually care, and in fact require a fuse or breaker between the SCC and the battery. Technically the wording is in there because of a conceptual problem on paper that they wanted to make sure would never happen, but this was written before the days of LFP and BMS...
