MQTT interface for Voltronic (aka MPPSolar, Axpert, Powland, EASun, etc) solar inverters.

Supports protocols PI30 and PI41 devices.

Exposed sensors:

• Inverter status
• grid_voltage (V)
• grid_frequency (Hz)
• AC output voltage (V)
• AC output frequency (Hz)
• AC output apparent power (VA)
• output_load_watt (W)
• output_load_percent (%)
• bus_voltage (V)
• battery_voltage (V)
• battery_charge_current (A)
• battery_capacity (%)
• heatsink_temperature (°C)
• PV input current (A)
• pv_input_voltage (V)
• PV input watt (W)
• Warnings
