Hello all! I need your help to read data from my MPP-Solar inverter. My goal is to close a relay when battery capacity is under 70% and open back when battery capacity is 100%. The relay is connected with a power generator. I would also like to display some data on an LCD screen My hardware setup is an Arduino Mega connected throw serial1 to a MAX3232 module which is connected to the inverter's RS232 serial port. To connect MAX3232 with the inverter I routed RX -> TX and TX -> RX So, I have the communication protocol and some other projects as a reference for example: QPIGS<cr>: Device general status parameters inquiry Computer: QPIGS <CRC><cr> Device: (BBB.B CC.C DDD.D EE.E FFFF GGGG HHH III [login to view URL] KKK OOO TTTT EEEE UUU.U [login to view URL] PPPPP b7b6b5b4b3b2b1b0<CRC><cr> (OOO is Battery capacity)

Hello We have been an engineer for more than 8 years in the market and have already developed projects for several companies using microcontrollers like ARM, PIC, AVR, NXP, Nordic, Texas, STM, ESP, Arduino, Raspberry among others. Using the general description of your project is possible to make a generic estimate, but the refinement of the total amount of work and the value of it will depend very much on the quantity and complexity of the features to be implemented, so I look forward to your contact for more details.
