- What happens when a Victron Energy inverter/charger loses battery communications? In this video, we discuss what happens and how to edit the inverter's default charging parameters, allowing you to charge your battery bank with the appropriate voltages until communications are restored. This example off-grid power system includes 48-volt Pylontech US5000 LiFePO4 batteries. When adjusting these settings, reference your battery's manual.

As a rookie, I am amazed at the possibilities you reveal and thankful for your intelligent assistance.
That looks like a nice van setup for traveling.
Ha! This system could power a small house, honestly, but it's a really cool system to feature - it's not as common to see 48V systems in mobile applications. This van is going to be used by the University of Montana and the US Forest Service to monitor air quality - it’s really hard to get science instruments out to prescribed burns, etc., so a mobile station offers a quick deployment option in the event of a fire. I'm excited to see the final product - we'll certainly share a link to a little story or case study, I'm sure.
Thank you for this video, definitely will help me with our system moving forward.
Great, so glad this was helpful!
Thank you! Looking forward for your next videos.
Thank you, Viktor!
Good morning, nice video congratulations....
I have three Pylonteck 5000 connected in parallel. I have a Chinese-made inverter that does not communicate with them. I set the various parameters manually in use.
They work well because I can see it from the LEDs on the batteries.
Can you connect a Victron Cerbo GX to connect and view the batteries in more detail? What software should you use then?
Thank you very much
Hey, thank you and good Q! You could totally buy a Cerbo GX and a touchscreen and just use it as a really expensive battery monitor. It would also give you remote access. You would also need a BMS cable, and you could even get a Cerbo-S, which would be a bit lower cost. And then, when you’re inverter dies you can get a Victron inverter and live the dream. :)

Thank you very much, very kind...
so should I buy a cerbo -S (this works with wifii), a monitor and a cable BMS RS485 cable? Thanks again
@@user-ml8gg6xv7w What you would buy is called a Victron VE.Can to CAN-bus BMS type A Cable
Hello! Very usefull video! How do we get MTTP back to "Controlled by BMS" setting?
Hi Cristian, thanks for the question. In a Victron system with a Pylontech battery, it’s an automatic setting. If there’s a BMS and it detects a BMS, it toggles it to "Controlled by BMS." Different batteries communicate differently (or don't communicate at all), introducing complications - and that’s where battery choice really matters. But in this setup, when reconnected (the coms cable is connected and if the DVCC is turned ON), the MPPT will automatically switch to controlled by BMS.
There is an error in your setting since Pylontech recommend the Bulk/absrtion to be 52 and float 51V
Hi Sebastian. Good catch, but those float and absorption numbers are based on an older version of the Pylontech batteries. The new Pylontech manual specifies a charge voltage of up to 53.5V.
