Solar Energy for My Lab

7 oktober 2023 | Door Jean-Claude Feltes

Solar power using mainly standard and recycled components. I use a reclaimed electric car battery to store solar energy. For the moment my main work is developing a stepup converter that can handle several 100W, to charge the battery. It incudes an MPP tracker

Solar Energy Experiment Kit van Velleman

14 maart 2017 | Door Thomas Scherer

Ik zat net na te denken wat voor cadeautje ik moest kopen voor de puberende kinderen van een vriend, toen ik de Solar Energy Experiment Kit van Velleman ontdekte. „Heel geschikt!“ dacht ik. Laten we eens kijken, wat erin zit en wat we daarmee kunnen doen.

50W Photovoltaic Solar Battery Regulator [080305]

31 januari 2013 | Door Sunil_M

This circuit was originally designed to power a small weather station but it is perfectly suitable for any other low-power application.The regulator was designed for a 10W to 50W 12V solar panel bit the electronics can be easily adapted for higher power

Solar grid tie inverter re-engineered

16 augustus 2015 | Door Pter

I repaired a chinese grid tie inverter for small solar systems, Input 50-100V, Output 230V 300W. The failure was in the reference voltage inside the µC ATMega8, it dropped down arbitrary. To be able to find this failure, I had to re-engineer the complete set and had to draw the schematics by

Simple lithium battery charger by solar:

3 september 2015 | Door gfaman

For another project (pollution detector), I tried to build WITHOUT dedicated IC (which are by the way very convenient) a lithium battery charger from a 5V solar panel. I decide to use a standard regulator LM2931CT (adjustable). I planed to use the low consumption version LP but I could not find

Programmable SMPS Power Supply and Solar Charger

4 juni 2014 | Door Lachlan

This is a flexible and programmable device that provides both a charger and two power rails. The charger includes MPPT tracking to support solar panel input, or standard DC input. The charger is designed to be used with 11.1V LiPo batteries and supports a maximum charge rate of 2A, but multiple

CAN Bus for solar PV cell monitoring

11 februari 2017 | Door bera

CAN Bus for Solar PV cell monitoring 25 KW roof top solar PV cell with 55 big panels each generating 24 volts which goes to a big black box to produce 220 volt single phase AC at the same time one thick pair goes into an invisible room full of batteries. Each shop has a
