My Christmas holiday project... Taking inspiration from some existing repos using pysolarmanv5, I've made a good number of changes, additions, fixes, improvements etc to suit my set up, which includes the ability to poll multiple inverters using different modbus mappings, and in addition from...

I've just started out on the journey to build my own battery, replacing my 3x5kWh of packs with a 2p16s 30kWh one. I've placed an order with NKON for some absolute bargain Envision Grade B 305Ah cells. The process of getting the order and import right dealing with taxes into the UK correctly...

Thought I'd post my DIY array as its (probably) a little unique because of the astroturf! On the left, above the kitchen, was my first foray to test the water for solar, how to hook up etc. Since it was a single story, which can be seen from bedroom doors, I wanted it to be somewhat aesthetic...

Following on from my last posts about getting metrics from inverters via modbus and creating grafana dashboards, I've now moved on to getting detailed stats from my batteries. This was driven by an issue I was having with my 3 packs deviating in SOC and an issue with the way the inverter handles...

So, back when I was being experimental I installed 6 panels on a low garage roof. The garden/rear is SSW facing (233SW). The house shades the panels in the late afternoon in the summer, and the winter sun causes shading from some nearby trees. I know it was not optimal, but it was a first...

I'm currently importing 30kWh of cells to make a DIY battery of a layout that can fit into a shaped area I have. My current set of batteries will be up for grabs, 3 of them 15kWh in total. They only have about 300 cycles, one much less. All grade A cells. Two are branded Basen Green. They...

After stalling for so long because of the frankly ridiculous pricing of commercially installed solar, I've now installed my own system. I was fortunate enough to have plenty of ground floor roof space in fairly optimal south facing positions, on top of a rear extension and garage. So far I...

Due to multiple chops-and-changes to how I've set things up and the space I have to put things, I've ended up with a surplus of batteries and cells... and wasted cash, I suppose :-( I have 2x Basen Green 5kw packs using CATL Grade A cells. One has 438 cycles, the other 377, of the 6000 rated...
