Good day guys

Just a quick question, can I mix old and new Pylontech batteries. I have 3 which are a year old and I want to add 1 more due to the current load shedding we are having. 

Thanks

You won´t have any problem. Each module is protected.

Hi

I have something similar - 2 "older" batteries" and a newer one.

the FW versions differ so experiencing some issues.

How do you update the firmware on the batteries?

 

Sorry to hijack your thread 😏

I would speak to your supplier. Updating firmware can be traumatic and I know of an Aussie user that bricked his module. I have 4 batteries with 2 different firmwares. Yes there are some idiosyncrasies but essentially they work. It is not an arena I would rush into.

What is the reason why  the "older'"  Axpert  Inverters were not Lithium-Ion compatible ?

Attached is the Leoch LFeLi spec sheet which claims it :   "Can use most VRLA Chargers for this system"

Many thanks

Possibly when the first Axpert came out, batteries like BYD and Pylontech weren't on the market yet.
