[RE-wrenches] BYD battery 12kW

Mon Sep 29 08:36:13 PDT 2025

Bryan  - The information you provided is correct.

The BYD HVL (all sizes) is the approved battery for the Sunny Boy Smart Energy 3.8-7.7 power classes (SMA did not have the 9.6/11.5 power classes when UL 9540 testing was done with the HVL line)

SMA Backup Home (external accessory like the Automatic Backup Unit with Sunny Boy Storage) will launch along  with the new SMA Home Storage battery (this was the unit on display at RE+). The Home Storage battery will be a monolithic unit with 19.4 kWh usable capacity. Backup Home will allow the full power of the inverter to be accessible in backup mode (unlike Backup Secure and Backup Select).

Best regards –
Mike

I indirectly received a response from SMA this morning and checking with Greentech Renewables to see if they are able to source them as they have them listed on their website:

The SMA battery is not yet available. Previously it was going to be self consumption only but when it does come to market it will be a whole home battery. Hopefully that is in the first half of next year (this is to the best of my knowledge of what I’ve heard internally). We do have the Backup Secure and Backup Select available right now. Beyond that, you are correct, the BYD battery is the only currently compatible battery.

I first became aware of the BYD when I had my 'LG only kinda/sorta works' with the SMA storage inverter debacle.

Not many making a high voltage battery now and shockingly to me, seems that 48V has kind of won the "beta/vhs" battle for now. Maybe the new SolarEdge Nexis ESS and inverter tips this again, but to answer your question, didn't find BYD from any "major" distributors during a cursory look.

We did just install the latest SMA inverter and we liked it...I'm a sucker for SMA string inverters and we enjoyed using the SunSpec functionality which provides great value.

I had someone ask me about this battery for a new SMA smart inverter.

I thought I’d run it by everyone.  My searches came up empty so I’m guessing it’s vapor ware?

thanks

Have you ever seen this battery and do you know anyone who sells them?
I have a customer looking for one or two and they are the approved battery for the new SMA smart inverters ( or so my customer told me)
