Good morning everyone Thanks for your feedback I will monitor the various cases over the next few days and then decide on the best self-consumption. My software (I can share it with you), use SainSmart relay board. I currently "manage" the inverter and relay board separately with C #, at finally I will use them both with the one software. Good day Best regards from Italy Pasquale

Probably I've resolved the mistery...thanks dropkick.. if non available the grid current, the "grid watts" are calculated as balance of all watts, considering some"scenarios" example if PVw-LoadW-Batteryw-inverter_consumption >=0 I assume GridW=0 if PVw-LoadW-Batteryw-inverter_consumption <=0 I assume GridW calculated as below, if you see my error is low ... in the formulas of Grid Calc I've considered 80 w inverter consumption, but probably the consumption is not constant What do you think? Best regards Pasquale

Thank you dropkick, below there is a screenshot of the my laptop in this moment, if you see, in RED in MultisibControl there is this value (now=0) "Grid Watts". I dont't understand where MultisibControl take it (probably caluculated by Grid current?). MultisibControl is connected by USB to the inverter. Best regards Pasquale

Thank you Coulomb for your answer and the file, but there aren't the informations necessary for me. There must be a way to read that value. I have read in various forums, relating to the Infini Solar inverters, that the QPIGS command also results in the "grid current" but not in mine and we in all the "Voltronic similar" inverters. This is the page ok the InfiniSolar RS232, the result of QPIGS command is different Best regards RS232 communication Protocol for InfiniSolar 3K (4).pdf

Hi My name's Pasquale, I'm italian. I ask support about an issue regarding "grid watt" or "grid current" to read from the inverter via RS232. I'm non a professional programmer, I've an inverter hybrid 7,2 kw (Voltronic brand) and I'm communicating via serial wit a simple program written in C# I can see the data with the QPIGS comand, but I can't see the grid current or grid watts. When I use QPIRI command there are the grid current but it is fixed (probably the target data of the inverter). This value is necessary for me because I would like design a software for the autoconsumption managing via a relay board. Acutally I can see "grid watt" on the Multisibcontrol software, installed on my laptpo pc, connected via usb on the inverter the but I don't know where is possible take this value, probably calculated from the "grid current", on the inverter with the RS232 commands. Thanks in advance Best regards Pasquale
