It is now time for a 1 month update! Can you guess how many kWh we produced? ;)

Dala, thanks for posting this. I can 100% appreciate the interest in the live data as I do something similar with my solar pool automation. It's pretty amazing once you realise how much energy is actually present in a square metre of solar exposure! I calculate live BTU measurements from my system (the system generates up to 100K BTU) based on actual flow and live input/output data as well as post a few data points from my SmarthThings hub, via hundredgraphs. I look forward to updates on your system as to how many kWh you are pumping out :-) Is the system based on microinverters, or is this a string system?

Here is live data from my pool automation system. You need to click the "All" button on the page to view the data...

So what are you planning to use for the powerwall? I'd take a wild guess and say LEAF battery..ha.

Hey Dala! Looking to use your can-bridge to upgrade my LEAF to 62kWh. It's a project for this year, but not tomorrow, as I've got to clear some other projects first AND make room in my garage.

After the conversion is done, I intend to use part of my current pack (2015 pack with 11 of 12 bars for a DIY Powerwall and the rest for converting one of my classic Minis to an EV.

I've watched a lot of your stuff on YouTube with a mix of awe and respect. Please keep up the good work!

Thanks, always cool with more secondlifestorage builds! Good luck with your project :)

I just got the 11kWh BYD battery connected to the grid! 8-)

Now to continue with reverse engineering the Modbus RTU protocol so that we can connect ~50kWh of spent LEAF battery packs instead... :D

Dala will soon become Finland's first grid-tie power storage billionaire! ;)
