Why do people still go for tesla powerwalls when you can get BYD batteries with 70%+ more capacity for cheaper ? You can buy a BYD HVM 22.1 kWh for 6000 euros

Why do people still go for tesla powerwalls when you can get BYD batteries with 70%+ more capacity for cheaper ?
You can buy a BYD HVM 22.1 kWh for 6000 euros now (£5200) vs powerwall 2 13.5kwh for 7000 euros.

- f1shy 10mo agoThose batteries must be connected to the internet to work, and the company could disable them anytime. Same for most of the inverters. I’m just hoping they don’t pull some nonsense like we have seen with other “cloud” devices. In that sense, I trust Tesla as much as BYD, and that is not at all.

- lm28469 10mo agoafaik it doesn't support bidirectional charging, I'd much rather cycle my standalone lifepo4 bank than my EV battery
- flakeoil 10mo agoYes, it does. I haven't tried it as a do not have the cable for it, but the user interface for discharge is there and the manual also talks about this feature. It's probably not ideal for running a full house (as it would require some other electronics and installations), but a couple of appliances should work.
- ok_dad 10mo agoThere are several types of bidirectional EV charging, the one most cars has is about a 1kW fused connection called "Vehicle to Load (V2L)" but the one you are discussing is what they call "Vehicle to Grid (V2G)" and in those cars it supports the full input and output of the vehicle inverter.
- f1shy 10mo agoIn germany was (still is) illegal to use the car as battery… it is going to change soon though
