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)
Hi Sir,
We can read your solar system and can fetch it to your destined location.
We are professional engineers and developers who do such projects from the last 10 years.
We offer you our skills for this project at very low rates comparatively without compromising the quality of work.
Let me introduce you to our company TURKTRONICS.
We are TURKTRONICS. We are team of professionals with 10+ years of experience in Circuit designs, PCB designs, embedded system solutions, mobile app development, programming and software development. We provide complete end to end solutions for all kind of development projects. IOT is our strong point.
In this bid, prototyping and shipping cost is not included however paying extra slight of money to include prototypes. We have the manufacturing facility and we produce the very high standard PCB boards and send ready products to customers doorsteps via DHL.
We care about our clients and help them to get out of any potential problem throughout the projects and also give post completion technical support if ever required.
We are very much looking forward to hear from you on this in coming days!

Hi,
I went through project description and willing to work on this project.
contact me to offer the project. I have commissioned 3 and 5KVA solar systems.. I can extract data and display it on screen.
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.
Hello, I'm experienced in the technologies required in this project. I would like to know more about the task. Please contact me, I have some interesting ideas
I learned c language and assembly language . I had strong grip on arduino coding . We work according to your satisfaction and try to recheck for more than 2 times . because your satisfaction matters alot.
Hello,
I am an electronic engineer, I have knowledge with power control, embedded programming, arduinon, PCB design.
I have the necessary skills to help you with your project.
I have
