Solar panel multiplexer sunrover has six solar panels 3 4w voltaic systems panels running into a set of quad power management boards that provide a multiplexing system so the six panels can be shifted to any of the three sunairplus based charging and power systems motor batteries raspberry pi2 batteries and the arduino power management batteries.
Solar panel multiplexer.
Solar panel multiplexer sunrover has 6 3 5w 6v solar panels.
These will be on a wing across the top of sunrover.
To test a 18v solar panel voltage output directly put your solar panel in direct sunlight set your multi meter to the dc volts setting.
4066 prevents the arduino analog pins from continuous potential.
Parallel series and a combination of parallel and series.
These solar panels have outstanding quality efficiency performance as well as value for money.
These solar panels are popular both in europe and the usa.
Solar panel is not directly connected to arduino.
Instead a 4066 multiplexer switch is used in between arduino and solar panel.
The outdoor enclosures are built fully assembled fully tested with a 30 to 45 day turnaround.
So when we want to monitor the power output by solar panel we short circuit the connection.
Theses are the diodes that i use they are the same ones that are used when building the panels.
4066 pins are controlled by arduino digital pins.
Connecting multiple solar panels.
There are 3 ways to connect solar panels.
Lg neon 2 panels use high efficiency mono n type cells which range from 325w to 335w power rating.
Description we stock the fully tested 16 channel multiplexer cards interface cables.
Ptot p1 p2 p3 p4 9v 3a 3a 3a 1a 90w.
If you connect these four panels in parallel all of them must have the same voltage and therefore will generate at the maximum possible voltage for one of the panels which means 9v.
You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit this means that if you have a panel rated for 20 volts you should set the multi meter to read up to 200 volts to ensure that you receive an accurate reading.
