Hello, First of all, I'm not sure that this topic is in the right forum category - apologies if not. My system also has solar panels, battery and a SolaX hybrid inverter. I am in the process of building a data acquisition system (using an Arduino microprocessor) and have succeeded in accessing the registers of the SolaX inverter using the Modbus RS475 interface. To this end, I contacted SolaX for the register map of the inverter, and (after signing an NDA) they supplied the information within 24 hours (very pleasing !!) I have attempted to make contact with Samsung for the equivalent information (register mapping) for their controller but cannot find an email address or messaging system on their website. Has anybody already got this information, or can they suggest any means of contact ? Thanks in anticipation !
