In researching a BAC4000 controller I see they claim to improve the power:

- 5kW with stock battery

- 7kW with stock battery with bypassed BMS

- 12kW with upgraded 60V battery

- 12kW with upgraded 72V battery

However the stock surrons claim these power outputs:

- 2020: 5kW

- 2021: 5kW

- 2022: 6kW

- 2023: 6kW

- 2024: 6kW

- 2025: 8kW

So these numbers would indicate the BAC4000 (with stock battery) is never an upgrade? However all the user experiences claim otherwise...

What am I missing?
