+|pv_total:| Optional | `none` | Provide a sensor for total pv power. If omitted the card uses internal logic to calculate this based on the pv1-4 power (W)
 |battery_voltage_183: | Optional | `sensor.sunsynk_battery_voltage` | Battery Voltage (V) |
 |battery_soc_184: | **Required** | `sensor.sunsynk_battery_soc` | Battery State of Charge (%) |
 |battery_power_190: | **Required** | `sensor.sunsynk_battery_power` | Battery Power (W). Requires a negative number for battery charging and a positive number for battery discharging. Set the `invert_power:` battery attribute to `yes` if your sensor reports this the other way around |
