Nice overview! Thanks for showing the pinout.

[@mattnewman8103]

Thank you for providing this level of precise detail.
Would love to see this with a Victron MultiPlus.
Also if you have two connected to victron MP and cerbo does the victron see the combined battery size and total current or do we need to also use a shunt?

[@Scat.original]

Thank you for a great detailed video

[@LithiumSolar]

So easy when you're inverter doesn't have buggy firmware! 🙂🙂

[@jnjentinc]

Do you plan on doing a video with Victron equipment?

[@jackjetpilot]

What is the procedure for connecting the communications for multiple SOK batteries together?

[@Just_An_Idea_For_Consideration]

Do you know if Voltronic also makes the mpp lvx6048wp? And if so is this info the same for that inverter?
thx

[@jeffcalder2349]

I am running the SMA Sunny Island 6048. When you get this figured out with SMA would please post something to help us with this devise? Thanks

[@MrJacquesvheerden]

Hi Sir, Nice video indeed. Do you have a link to download your vs of Pbms please. My vs does not have that 1st step to select the battery protocol.

[@RussellHogan]

Close loop communications with the SOK 48V and LVX6048WP MPP Solar do not allow me to adjust the low voltage cutoff. Close loop sets it to 44.8V. That's way too low, correct? What should I do?

[@mikloskalman2841]

I have a question. I have the same inverter, but with a pylontech battery, I only use the brown and brown/white cables for the communication cable, what is the green cable for? Thank you for your answer in advance! Miky

[@RiazMemon-kk5id]

That is the ground pin which runs from pin 8 of inverter and pic 6 on battery

[@igorkvachun3572]

Yes👍🔋 ⚡💡

[@Vibe77Guy]

Would a similar procedure work to connect the Sungold 48v 5kw inverter to an EG4 48v 100wh rack mount battery?

[@HighTechLab]

No clue, it's a totally different inverter and battery.

[@Vibe77Guy]

@@HighTechLab
Is it not still a Voltronic inverter?

[@HighTechLab]

@@Vibe77Guy as much as Chevy is a GM

[@RussellHogan]

Mine says paceic. It will not change when I select pylon_485. I get a write error. Any idea?

[@therust2001]

Did you figure anything out having same issue

[@RussellHogan]

@@therust2001 No I did not. Let’s keep each other posted as we figure this out.

[@super2222sd]

hi can you give me the pinout for the rs232 port please, thanks

[@CurrentConnected]

Please source the RS232 cable from your point of sale for SK48V100 batteries.

[@brucecarter5856]

Watch out, does not communicate with eg4 6500 , error 61 pops up

[@cseaton42]

Ever get communication working with EG4 6500EX?

[@cseaton42]

@currentconnected Anything to say about this? I'm about to try this with EG4-6500EX-48 and wonder if you've actually connected these batteries to that specific inverter.

[@HuyTran-zy9sv]

@@cseaton42 Have you had any success with this? I just bought an SOK battery locally but have not have communication cable to try.
If you got it working, which protocol to set to?

[@quickquote1568]

Voltronic Power, high frequency, transformerless inverters. No thanks! Low frequency, transformer based inverters are so much better that these units.
