13.25v on Lifepo4 battery is not for sure 30% but aprox 75%, I am really surprise this has not taken in consideration rather than specific peukvert %

dont buy the dongle. Just use the vrm and victron connect app

How do you wake up a Lifepo4 48 volt 200 ah ATV/golf cart BMS when it quits out in the field and you have no charger to reset it? It has a separate 12 volt AGM battery to power the winch and LED lights. The 48 volt battery charge connector has an Anderson plug. Can I make a jumper that connects the 12 volt to the 48 volt battery through their charge ports that will reset the BMS on the 48 volt battery? What about backflow current from the 48 volt into the 12 volt if it resets? Also, will a 12 volt 3000 amp portable battery charger reset the BMS without damaging either?

Talking too much

Why do you have a green (ground?) wire going to the neutral bus?

Great video! Just wondering how to pull the ferrules back out? Any thoughts would be appreciated!

20 kw/h is not really what i call massive, we have 80 kw/h on our hotel with batteries system for day and overnight. Some people with big firms and factories put well over 3 Mega watts/h but for residential use it might be enouth that shed is small.

it's just surface charge. Fooling the charger. Trick is not to drain the battery in the first place.

I have a 48v lifepo4 battery. 56v when it is fully charged. what voltage should I set to wake it up?

Can I use my dewalt 20V battery?

What if my lifepo4 battery is 24V/200ah? What size lead acid battery would I use? For how long would I boost the lithium battery? You explain my situation to a tee. Very frustrating dealing with customer support

Wish they made a feature to have two screens.. In the RV coach area to monitor and a second in the electrical bay for troubleshooting. Yes you can monitor with your phone but it isn't as convenient. The largest advantage Cerbo over the EKRANO has is the amount of cables that need to be routed on a remote display.

Great video….very informative!

Can i use 240v 60hz ac bulb for 12v battery

thanks mate. this video was very useful

Which ac port would you recommend for grid tie using current transformer to prevent backfired with ess

Hi Dexter ,how will this inverter fare with a well pump? My pump is 3/4 hp 240v inrush is 36a it runs at 7.4

Well explained!

Can I us 12v battery to jump start a 24v sleep battery

thank you!

What dongle would I need to program the multiplus on an iPhone? Thanks.

I do manufacture and sell precharge units. I do not mean this as an advert but as I do this I would not recommend any method other than a precharge unit specifically meant for doing it only because whether you are using a power or a resistor you need protection for that and it’s recommended to use a switch that can go with the voltage issues only because, it’s a lot safer, especially if done repeatedly

So, could you use a 9 volt alkaline battery the rectangular Duracell you find in smoke detector to kick smaller batteries in the guts?

Nice. What do you do if jumping it kicks on the charger but take off the jump battery and it shuts off again?

Hello and congratulations for the video I come to you for the multiplus can we use the ACin input not permanently on the network but just connect it to a 230V 20A socket (France) to just supply the ACin input to charge a park battery at night rate and use the ACout during the day to restore the energy to my electrical panel? because connecting the ACin to the network bothers me a little because it requires a lot of steps because if there is a risk of injection into the network it is necessary to go through a Consuel I would especially like to be in self-consumption and from time to time be able to close the multiplus with a source inverter in my prolonged absence and switch to the direct network laurent

You guys do incredible work. Well done.

If this issue is so widespread these should come with low voltage cutoff switch built in.

I bought a cheap android tablet for under 100$ and connect via IP works great!

The mounting hole(5191) is 3/8(#10) NOT 5/16(#8) as stated...

I also own a mpii and I Can Clearly hear 50 Hz. But on your recording, I only hear pink noise.

Do you have the manufacturer or model numbers to any of these 48v inverters "of similar size that draw 2-3 amps" ?? If ANY 2kw (or similar size) inverter pulls that sort of current at 54.63v (48v) then there is definitely a malfunction with said inverter. Maybe you could actually compare the idle power consumption instead of comparing just the current draw of a 48v vs 12v inverter if that is what you actually meant. Two different scenarios here. Thanks for the looksy inside the Victron inverter.

The stupidest product ever is a charger that won't work because the battery is dead.

My car battery is 5v can it be rechargeable

Yes thanks

Great video, can you use the new dark theme with this interface ?, It looks like the options are missing under display that might only be available when a physical screen is connected via HDMI ?

I can even see the cracked cell omg don't do this

This is a genius idea regarding using a light bulb! My electronic shop doesn't sell the resistor ceramic that I need but they have a lot of 12 volt light bulbs that will work! Thanks for the idea man!

I noticed you guys aren't listing the SOK batteries on your website anymore. I really like the two I bought from you.

Wish I would have known this trick before I blew up my inverters input capacitors hooking it to my battery. I have an old test light with a light bulb in it that should work after I finish replacing the blown capacitors.

Excellent video, thanks for putting this out there.

Didn’t even talk about bluetooth connection!! I can’t get this far!! Always spins at 80% then times out. even after putting in the correct Bluetooth PIN tried keying in 000000. Still no connection. Went through all the suggestions and trouble shooting but to no avail. Reloaded the app, rebooted Cerbo, restarted phone. Still will not connect to BT. 😢. Maybe I need a new Cerbo ? Any suggestions out there????

So I have to pay Victron even more money to actually configure and use the inverter that I already paid over $1k for?

Can we see it switch back to grid too? I think it might be just as fast

I bought 2 24 volt inverters from signature solar I didn't know that you had to get a code so I'll have to contact them if I have any questions can I reach out to you

Wow, what an informative video… thanks for taking the time. Those buggers are spendy, but that was impressive.

My new 206 Ah battery reads 10.6 V. SOK says I need to wake it before my 40A MPPT will recognize it. How depleted is 10.6V? Once it's charge to 11V might the controller power on? Can I then connect solar, or must I use the charger until battery terminals read 14V? Help! Great vids!

A 48 Volt output is not high enough to fully charge a 48 volt LFP battery. Even 57 volts is not high enough. The output should be at least 58.4 volts, or 3.65 volts per cell.

You guys are fantastic. I'm so glad I bought my SOKs directly from you - the customer support has been great.

A totally dead lead acid battery is the same with most chargers.
