Is it available for purchase yet?

 

Also I have  two 280ah indoor wallmount, can this be added using the parallel indoor cable?

Great news - Impressive evolution!

  • Could you please offer tech details about combing this unit with existing 280Ah Wallmount?
  • For instance this new unit has Active Balancing
  • How will the separate Wifi connectivity be leveraged
    • Just for Firmware upgrade? Or more data about battery performance (like cell level voltage to Monitoring server)?

Appreciate the accessibility of the BMS for long-term maintenance.

@t345

currently only available in US

Yes, however, you will need to set the New 314Ah indoor battery as the master battery and this configuration is not a UL9540 configuration.

I'm gathering more details on paralleling these batteries together and also about the Wi-Fi Antenna.

It does have active balancing.
