Do you remember my post about the first steps to build my own Energy Storage System (#ESS) for my home energy backup, and at the same time increasing the self-consumption ratio of the electricity produced by my #PV installation in normal conditions?

Today, I'll share a small update :-) I've done it. In general, the prototype was on my second desk for a while, tested and ready for production use, but I wanted to pack it into a nice enclosure. Unfortunately, most of them available as empty sets are ugly and rack-based.
I wanted to hang it on the wall, and there were some adversities to solve. The weight of the cells is the main one.
I found a nice, solid, steel cabinet, with perfect depth. I've made some measurements, designed the stand for the cells, and started planning how to arrange other elements inside. My design includes a cell compression, BMS location, and fuse ... and a few elements are still not ordered, as I haven't decided which manufacturer I want to use.
What was achieved, is nice capacity in the price I've paid for the parts. It's 16kWh built with cost a little higher than popular ESSs with 5kWh capacity.
The next steps are to add some main switches, additional fuse, and DC connectors on the external part of the enclosure plus cut the hole in the steel door to place a display and communication ports.
Now the ESS will charge with the solar-produced energy during the day, and discharge during the cloudy hours and night. And from today, it is connected to my home electricity network in production mode :-)

well okay, Silk Sonic!
