How to Connect Multiple Solar Inverters to Central Web-Based Data Monitoring System?

We install Solar Panels.
So we have many sites where panels are installed and along with solar panels Inverter are also there to regulate power.
So we want to monitor the output of these Inverters, for this we want to make a website where data from all inverters can appear on single screen.
So here first query arises how inverter output will reach to website?
We shared our query with few Inverter vendors, they tried to answer it hard but failed.
So I am at EEWEB to discuss this with Experts.

Shishupal, most inverters have a serial or wifi port where they can be connected and interrogated.If your inverters have a serial port then you should be able to design a microcontroller board that will talk to the inverter, recover the required data, and then transmit it to your server - you could use GSM / 3G for this and either transmit the data regularly (once a day / hour etc) or poll the sites individually. It sounds like you have the server / website expertise to correlate and display the data?   Does this help?

Enphase makes a system called Enlighten that appears to do what you are looking for.  Unfortunately, it only works with their micro inverters.Each of their micro inverters sends information over the powerline to their residential gateway. The gateway connects to the homeowners' network through Wifi or an hardwired Ethernet connection. The homeowner can view the information on a PC or smartphone, and can optionally share the information publicly via Facebook or other social networks.  There's also an installer view that allows the installer to see all of their installations.I think there are other companies that make similar systems.

HiFirst off, at the sites these are installed do they have any communications? For example do they have internet?A company I can highly recommend is www.ff-automation.com  they provide remote monitoring capabilities for all sorts of facilities.

do you want to do it on your own , hire an established company or a freelancer? the previous company is a great one but consider hiring good engineers who can do that a good price too. Now ,you will for sure make sure to know if your inverters have the required ports needed for Gsm or internet communication. If it is the case, depending on the manufacturer of these inverters, a design with appropriate technology will follow.
