What is a good meter/data logger that would allow me to consume it's data through an API?

Hello,

I'm a software engineer recently working in a solar firm and we're building a web application to manage all of our project's consumption/injection and performance data.

Everything works just fine with ABB and SMA inverters, they provide an API and we're consuming their data with 0 issues, but for all other brands, we're kind of in the dark.

Both Fronius and GoodWe say explicitly that they have an API, but when checked it was not really what they said it was, Fronius calls it's Solar Web an API and GoodWe are bad at replying emails and providing useful info (in fact we may not work with those products anymore because it's such a hard work to contact someone that would answer). Ingeteam and Huawei are yet to reply to us.

So I started looking into meters or data loggers that'd do the job we need. But most sales representatives in my (3rd world) country don't really understand that we do not want to manually export CVS from their websites, we just want an API to query data in the way we think is best.

I am new to this world and the first time I ever saw an inverter was like 1 month ago, so I don't know much about Modbus RTU or SCADA systems, but for what I've studied, it's not what we need, but I might be wrong.

So I have come to you for clarification, am I drowning in a glass of water? I just need to query data from a server into mine, is that too much to ask? I've been looking and reading manuals for days now.

I hope someone can share a light!

Thanks in advance /r/solar friends!

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6

Does anyone have any contacts for professionals who I can hire to complete this process for me? Or any tips for completing this process?
