    Multiplus - AC Input Control for SOC control

    The SCC has an Equalize button in settings, so that's pretty easy to implement

    Multiplus - AC Input Control for SOC control

    Thanks for the info, Settings for AC Input Control, and others were set using a MK3-USB and my phone through Victron Connect. Yes I'll turn the Multiplus battery monitor off, that was just an experiment. Wondered about the GX requirement, I likely won't get one given the cost of a Cerbo GX...

    Multiplus - AC Input Control for SOC control

    I have a BMV-712 and Victron Multiplus 12/3000/120-50 120V that are networked together using VE Networking. I'm trying to implement AC Input Control to get battery bank SOC to stay lower than 100%. I've set up AC Input control and it honors parameters on Load Condition, but doesn't start...

    Wire Size from panels to SCC?

    I have two large panels with an ISC of 10.23a each (2x in parallel = 20.46a) and on the sticker the max fuse rating is 20a. They have 12ga leads, would you recommend a 20a fuse on each panel?

    Wire Size from panels to SCC?

    Thanks for the tip on the Y cable, that will be easier. Can you expand on why a fuse isn't needed for two panels but would be for three? With a 32a DC breaker on the input side to the SCC (due to the 8ga wire), I'm concerned about 12ga wires on the roof having issues before the breaker trips.

    Wire Size from panels to SCC?

    Just finished mounting a pair of 395w panels to the roof of my RV, and want to make sure I get the wiring correct to the SCC. Panels will be wired in parallel to a Victron 100/50 SCC. 49.5 Voc 41.4 Vmp 10.23 Isc 9.55 Imp Max Series Fuse 20A Planning on using wire sizes below. Panels have 5ft...

    Need help matching used panels to Victron 100/50 SCC

    I've got space for 4x of the 250w, or easier space for 2x of the 398w. The 100/50 SCC shows support for up to 700w so I'd either be 300w or 100w overpaneled, is 300w too much?

    Need help matching used panels to Victron 100/50 SCC

    5th wheel with 300ah 12v LiFeP04, Multiplus 3K, BMV-712, Orion 12/12-18 and I want to add some solar. Planning on a Victron 100/50 SCC and 2-4 used panels around 800-1000w total, and concerned about getting the VOC too high but 150/70 or 85a models are nearly double the price. Used panels...

    Anyone had lightning strike your array and get saved by over current protection?

    It's what's in surge protectors to absorb the hit during a surge. The Hughes Power Watchdog 30a and 50a models have replaceable surge modules, so you don't have to throw the unit away after it protects your RV from a surge event.

    Insight on my 48v 5th wheel solar equipment please.!

    I used this schematic which uses a manual switch to bridge L1/L2 when on 30/15a shore power, generator (power assist) or off grid entirely. This lets the Inverter power both sides of a 50a split phase AC box, and it works great. In my case the form factor of the older Victron Multiplus was much...

    Victron Multiplus charge settings for SOK batteries

    With my Multiplus 3000 float set at 13.6v I see voltage is sometimes at 13.7v or slightly above. Is there an issue with a bit of draw via RV lights etc once the battery is in float? I do see that but it doesn't last long before I see power going back in.

    Concerned

    Pre-order means they are awaiting stock, these days the arrival could be hard to predict but I wouldn't worry about the safety of your funds. On the slow response they are likely just very busy.

    Current connected is a reputable business based on my orders. I'm quite sure you'll get what you've ordered.

    SCC choice for these panels?

    I've looked at new 200w panels and they are about $1 per watt or slightly more. The 260w used panels are .25 per watt, and at 75-80% output would be roughly the same as 4x 200w panels. I have space for 4 panels regardless without putting them in places I really don't want to due to shading or...

    SCC choice for these panels?

    Considering used solar panels for our RV, and trying to see what MPPT SCC would work best with them. I have an SOK 12v LFP battery bank, currently charged by a Victron Multiplus and monitored with a BMV-712. There is room for four panels with little to no shading issues (flat mounting), but will...

    Multiplus Temp Sensor

    I'm guessing this was added in the latest firmware, and has anyone tried it? Edit: This does appear to work Created VE-Network on the 712-BMV, then added the Multiplus to the network. Used a load to bring the battery bank down a bit, then set low temp cutoff above ambient with the MK3-USB and...

    Victron Multiplus charge settings for SOK batteries

    Interesting, my 100ah SOK's arrived at 13v, which is about 30% and what I've read they ship at. I think the 206ah use the same BMS as the 100ah batteries have, so have the same limits. At 4x 100ah batteries (400ah total) I'd be able to charge at 200 amps, but my Victron Multiplus 3000 maxes...

    Multiplus Temp Sensor

    I agree, trying to figure out which SCC size I'll need given the panel setup I'll be using. Will start with 2x 200 watt panels and possibly expand to a total of 4x panels and 800 watts. (flat mounted) Looking at these: https://richsolar.com/products/200-watt-solar-panel which have a Voc of...

    Multiplus Temp Sensor

    Solar will come later, but it would be a Smart SCC if I end up going Victron. I'm also looking at Rich Solar and Epever, but I do like the interface on Victron Connect

    Multiplus Temp Sensor

    What is a smart sense temp probe? I've got the 712/shunt and Multiplus bluetooth dongle, but the temp probe I have bolts to the battery + and then two wires/ferrules go to the 712, nothing smart about it.

    Multiplus Temp Sensor

    Thanks for all responses. Can I run a cable from the VE.Direct port on the 712 to a Victron SCC, or does getting temp info to the SCC require a Cerbo GX? Off topic, will a Multiplus wake up the BMS on my SOK if I forget to use my pre-charge button, or it otherwise disconnects from batteries?

    Multiplus Temp Sensor

    Any reason to install the temp sensor that came with the Multiplus? I already have one hooked to a BMV-712 to monitor SOK battery temps in my 5th wheels basement. The Multiplus doesn't use temp compensation with LiFeP04 correct?

    Victron Multiplus in AC passthrough only during staged RV install?

    Tested and confirmed, Victron Multiplus will pass AC power without seeing batteries. (It was configured with a battery on the bench) Turned the charger off using a MK3-USB and there is a low battery error, but it will work fine until my 4/0 cable arrives and is installed.

    Victron Multiplus charge settings for SOK batteries

    Will have 3-4x SOK 12v 100ah batteries in parallel charged by a Multiplus 12/3000/120-50 I asked Current Connected and SOK for charge recommendations and got different info. Current Connected says 14.6v provides better cell balancing, likes higher float voltage and charge current. What settings...

    Victron Multiplus in AC passthrough only during staged RV install?

    Will be upgrading a 5th wheel from FLA to LFP batteries, along with a Multiplus 3000 12v 120a replacing the current AC/DC converter and 1200w inverter. Completing the install in stages would make things easier and maintain RV use during nice weather. Any issues with connecting AC In/Out to the...
