Solar PV datalogger and upload to Thingspeak / PVOut

26 januari 2018 | Door Wim312

ESP32 datalogger between Danfoss ULX 3600 inverter and Thingspeak / PVOut. The Danfoss ULX 3600 is a single-phase Unilynx inverter that transforms the DC voltage (PV solar panels) to AC 230 voltage (Grid) and has an RS485 interface. The ESP32 datalogger receives solar information

Cheap, accurate 12V battery checker for solar banks [150077]

20 augustus 2014 | Door Ram

This little idea came about when I was thinking about an accurate way to constantly measure the voltage of each battery in my solar battery bank. A lead acid battery's voltage remains fairly constant as it discharges. As the attached chart indicates, a no-load voltage of 12.6 volts means 100

Maximum Power Point Tracking for Solar Photovoltaic Panel [150411]

6 juni 2015 | Door bera

MPPT – Maximum Power Point Tracker Funny most of the solar panel that I see around my place even some are very big from 25KW to 2MW but none are controlled by any MPPT. 25% power is straight away lost for poor operating zone of parameter. For battery chargers

Solar plant telemetry - using image analytic with machine learning

14 april 2020 | Door bera

SCADA is too old & too scary: After the success of the hydel plant telemetry project at less than INR 10K my boss thought why don’t I take up a similar project for the 16 MW solar field! The solar field has a total 15MW PV setup. The setup is about 4500 meter at a

16 september 2013 | Door gfaman

Many of us want to receive regularly a picture of a place, which can be a beach for activity, a second house, a place in mountain for hiking or biking. Also, it can monitor a house under construction or other daily monitoring needed.But if there is no power, it's become complex. Solar

SolarBench: test your solar panel up to 300W with a MPPT matchbox

12 februari 2016 | Door greenlicium

What is the power really delivered by this solar panel? is that panel working properly? are the real performance derated because of aging or counterfiet origin?This small and convinient tool can help you selecting and sorting panels by finding MPPT automaticaly. It also displays Voltage

Positioning a Solar Panel to a light source (sun) with Arduino and stepper

31 maart 2018 | Door Guidovanb

This project makes a stepper motor control the position of a solar panel to make it turn to the position that it recieves the most light from the sun. After sundown (light dims below a set level) the unit turns towards the 'morning' position. (east) The software that drives the
