Specifications

This sensor will be tested by using a power generator and by sending 30 amps into the

sensor. This should relay a voltage reading, which should show that the sensor is

reading 30 amps through the wire. We will then test the voltage sensor by using a

multimeter and then see if the reading off the voltage sensor matches the rest of the

system. We will then vary this to determine that the sensor is acting properly. There will

also be a fuse in the system in case there is a short we will not damage our sensors it

will just blow the fuse.

7.2.3 Complete Power Generation System

At this point, the wind turbine and solar array sub-systems should have already been

thoroughly tested and confirmed to be working properly. Now it‟s important to combine

the two systems and use them to charge the battery, making sure that nothing changes

in the power generation of each system individually. In order to perform such tests,

methods that are repeatable yet able to be performed simultaneously must be used.

The only option for such tests is the use an electric motor which we can specify different

RPM‟s to spin the turbine at, and lights so that we can raise and lower the amount of

light incident on the panels in specified intervals. These factors should be varied in the

same manner as they were when the generators were tested individually. While these

tests are being performed, the system must be closely monitored to make sure that the

charge controllers and/or the battery are not overheating.

We must also perform multiple real world tests. Such tests will show that not only does

the charging system as a whole provide ample power mathematically; it also does so in

real life. This will also allow for additional problems such as overheating and moisture

related issues to arise due to the environment. Thus, the temperature of the charging

systems components must again be closely monitored in addition to any leaks in the

enclosure or possibly moisture buildup. The battery should be completely discharged,

and then connected to the generators and left to charge. The Voltage of the battery

should be measure at a set interval, say every 30 minutes, in order to obtain a rough

plot of the charge level vs. time. It should also be ensure that the battery is back to fully

charged in less than 6 hours, as was originally specified.

7.3 Power Storage System Testing

There are a few different aspects of the power storage system that must be tested to

ensure correct functionality. The first, and perhaps the most important, is the runtime of

a laptop and projector when no power is being generated. While this is very important, it

is also very easy to test. The basic idea is to connect a laptop and projector to the

system with a fully charged battery and with the power generation sources

disconnected. It is preferred that the laptop and projector are at the higher end of the

spectrum when their power consumption is compared to other similar electronics. The

devices will be left on until the battery voltage drops below 10.5V, causing the inverter

to shut down and as a result the electronics finally turning off. This will be considered a

full discharge cycle real world test. If at the end of the full discharge cycle the

electronics ran for more than 2 hours, we have successfully met the goal. Perhaps a

more accurate and repeatable way to test the same thing but at maximum designed
