Lead acid support for DEYE inverter?

[mace-de]

Would it be possible to add a Support for lead acid batteries on Deye Inverters? The two main parameters battery voltage and current could be read from the inverter Modbus registers 587 and 591. This makes it obsolete to acquire them by hardware. Maybe a NTC or DS18B20 temperature sensor could be used on a port pin for temperature compensation. All other Parameters like

• Capacity
• Absorption Voltage
• Float Voltage
• Equalisation Voltage
• Temperature coefficient
• Battery resistance
• Charging efficiency
• Maximum allowable discharge level are constant has to be configured by the user. With these parameters a charging curve and a SOC could be calculated to be transferred as BMS-Data. I think I am able to stumble the above together as a separate arduino project with no additional features and unusable for others. But maybe it's better to have this included here. I for my part, I'm definite not able to integrate this in your project code. Regards Oliver
