Pylontech US2000B Plus V2 vs US2000C vs US2000C Plus

Hi,

I currently have US2000B plus batteries and I’m looking to add a couple more batteries to my stack. The problem is, I can’t figure out what’s what with Pylontech’s current lineup in the 2.4kWh capacity.

Until recently I was convinced that the US2000C would be the one to get, assuming it is the replacement for the US2000B plus (which I also assumed would be discontinued in due course). However, now another two similar models have cropped up:

There’s the US2000B plus V2:

… and there’s also the seemingly new US2000C plus:

Does anyone know what the differences between these models are? Given that I currently have US2000B plus batteries, which should I get?

Thanks!
Pierre
