Integrating PV and battery monitoring systems

I have 22Kwp solar PV system with fronius inverters and 36 Kw of solax triple power batteries both have web based apps but they don’t integrate is it possible to do this and increase the functionality by monitoring other sytems?

Hi Justin
Almost anything is possible with enough time, money and determination!
Are you looking to integrate the data from these into emoncms? There are a few examples of getting Fronius inverter data integrated into emoncms, either by direct polling of the modbus, or using http requests. I’m not familiar with the Solax interface but if they have a web based data server then it should be possible to get that data into your hands. I have a Fronius Primo inverter coupled to a Selectronics inverter/battery controller and have been able to get access to all the data needed. If you can be more specific in your requirements, I’m sure you will find all the information you need from the OEM community.

Justin,
Is this what you are looking for ?

My Solar PV Battery app Emoncms

A couple of years ago @sysriqo adapted the MySolarPVdivert app for use with batteries. The pull request was never merged as there was an unfinished discussion on whether to split the app out into its own separate app. Picking up from that point, sparked by recent discussions on this topic, thanks to @miker @haffle @Zarch , I have adapted @sysriqo’s pull request to use the most recent version of the mysolarpvdivert app and made a few other changes. Thanks @miker for helping with testing! The “My…

Thanks for the feedback. I have discussed some solutions with a software engineer who thinks we may have a solution. I will post this if it is relevant to the group.
