I use this hack i a citroen c1 EVie electric car.
The ctek xs 3600 have 4 charge modes:
- Desulphation: pulses with high volt/amp is made
- Bulk: after 80% charge, the charger deliver a constant current until battery i fully charged
- Absorpsion: charge up to 100%, current will fall but the voltage will be constant
- Puls: this is a puls charge mode, it maintenace the battery, a keep it in goog condition. This mode charge between 95% and 100%. This is the mode used when charger is connected in months.
This MPPT solar charger is build around Tim Nolans open source MPPT solar prototype project. I made a print layout for the MPPT solar charger, and below you can se how the mechanical mounting was meant to be. Continue reading
Update 27-02-2016: I have stopped working on this project, and therefore i no longer support the code/schematic and printed circuit board.
Update 20-12-2014: this arduino mppt charger shield is tested and works withTim Nolans version of the arduino sketch. The placement of the mosfet’s on th
e circuit board was designed to fit to a Aluminium U profile.
Just make sure you don’t try to cool down the power from a 9 map solar panel, with this small aluminium Profile.
To do that, you need a bigger cooling plate. You can find a link in the article below for an example of how to use a salvaged pentium 4 cooling plate. Continue reading
SunTracker running on an Arduino web server and is designed as a LEGO model.
This Arduino suntracker /solar tracker called: ‘Sun-Trackuino-Delsol’.
I use a Arduino with nuelectronics ethershield which is used a few times in the past as solar data logger and stokerlogger / controller with Arduino is a WebClient (Remember use ARDUINO IDE 0018 to ethershield from nuelectronics! ).
Unfortunately this shield is discontinued but you can use any other arduino ethernet shield but you must change the code. Continue reading
This is v.1.1 of a simple solar inverter made with arduino and old 12 volt trafo’s from scraped electronic and halogen lamps.
Read techmind.dk GENERAL Disclaimer before you continue.
This version 1.1 if for single coil trafo’s also i made a prototype v.1.0 printed circuit board for trafo’s with center input.
