Field trial of the 1KW (2.4KWh) power station begins

Dropped off the 1KW (2.4KWh) power station with Essam today to get measurements of how much electricity his food truck uses.

He would like to purchase an 2000W 1500Wh power station so he can run lights/fridge/etc. when he's off-grid.

So be collecting and analysing the measurements from today should say whether this is possible :)

It look likes the van uses less than 40W for lighting and another 300W whenever the fridge compressor kicks in.

But I will have detailed info from the sqlite3 database when I retrieve the unit at the end of the day :)

Only just portable!

Safe home again! After a grand day out :)

So the unit was deployed at around 13:30 and removed around 16:30 so around three hours of data. Essam had been there since 12:00 or so so the fridge had 90 mins to cool its contents.

Here, is the graph for the power drawn during that time:

It can be seen that time on the graph goes from 9:45 to 12:30 (so about 3 hours). The time was set wrong on the computer gathering the data :)

At first the fridge is on all the time drawing 372W peak but after 30 mins or so starts turning on for 5 mins and off for 8 mins in a cycle. When it was off typically 40W was been used for lighting.

Later in the day Essam turned on the extraction fans which raised the power draw by about 130W

So to summarise the food wagon never drew more than 600W and over the 3 hour test period used on average 300W continuously (assuming the extraction fan on).

So the 2000W 1500Wh power station Essam is thinking of buying can easily accommodate the 600W peak power and would supply 300W for 5 hours.
