Shannon Town Sustainable Energy Community (SEC)

 Finally got round to making a small video explaining how to get the most from your Smart Meter data :) What this video illustrates is  how to make the most of your Smart Meter by: 1) register your Smart Meter at https://www.esbnetworks.ie/ then displaying your usage / generation data on that portal 2) Downloading this ESB data to your computer 3) Uploading this data to https://www.energypal.ie/ for a more detailed analysis and cost breakdown Enjoy.

Dropped off the 1KW (2.4KWh) power station with Essam today to get measurements of how much electricity his food truck uses. He would like to purchase an 2000W 1500Wh power station so he can run lights/fridge/etc. when he's off-grid. https://iallpowers.com/products/allpowers-2000w-portable-power-station https://www.youtube.com/watch?v=cScqnOofMRQ So be collecting and analysing the measurements from today should say whether this is possible :) It look likes the van uses less than 40W for lighting and another 300W whenever the fridge compressor kicks in. But I will have detailed info from the sqlite3 database when I retrieve the unit at the end of the day :) Only just portable! Safe home again! After a grand day out :) So the unit was deployed at around 13:30 and removed around 16:30 so around three hours of data. Essam had been there since 12:00 or so so the fridge had 90 mins to cool its contents. Here, is the graph for the power drawn during that time: It can be seen that time on ...

Finally, added two handles to power station.  I just have index.html code to finish now :) Which needs to work as a hotspot and provide graphs based on stored sqlite3 data tables.

These have been gathering dust in the shed for the last year. So will see if they will still take a charge. The two 100W panels and epever charge controller were recently recovered from being leant to the Shannon Tidy Towns 40' Container. Based on an Epever LS2024B https://shop.thesunpays.co.za/products/epever-ls2024b-solar-charge-controller-20a-pwm And monitored using a Blynk code on a NodeMCU.(A version can be found on my laptop under  Tracer-RS485-Modbus-Blynk-V2.ino as not yet shared to Github) The charging is monitored here..

  Here's the inverter inside the wooden power station housing. So I finished weatherproofing the 1KW power station housing earlier this week and tried it out in the garden. The DPC (damp proof course) plastic stapled to the pine should allow the unit to survive the rain for a few hours :) The unit provides AC out (1000W for 2 hours) and AC in and PV in to recharge the batteries. The unit needs bigger wheels and some kind of handles to allow it to be wheeled around more easily. The 1150W microwave was too much for it and caused the inverter to beep before shutting down. (Reducing the power rating on the microwave made no difference). A 700W toaster worked OK. As it only draws 761W The PV input also worked OK. This allows the inverter to charge the batteries using a solar panels. And the inverter's display showed the batteries PV charging :) So bringing the power station back inside the kitchen to try a 1000W load on it. It is pulling down 900+W quite happily for tens of minutes ...

Here's the agenda items: 1) How can we grow our SEC? (Youtube, etc.) 2) Sustainability day in Shopping Centre 3) Information table 4) Starting an Energy Masterplan 5) Keeping in touch with other SECs 5) AOB
