I have 2kW of panels on my balcony and 4kWh of batteries. I'm happy with the setup. I expect it to pay for itself in just a few years. The only thing I wish it had is open APIs to control the inverter and the batteries, ideally over bluetooth, so that I'm not forced to use an app.
- effdee 7mo agoIf port 502/TCP is open you can probably access it via Modbus protocol. Implementing a Modbus client is trivial. My rebranded Fox ESS hardware has it enabled and there's even official documentation of the so-called "registers".
