As you may know, I wasn’t enamored with the marketing hype of the so called “Solar Generators” last year. In fact, I was worried that readers would confuse them with actual gasoline or propane generators, which they definitely are not.
Enter the Portable Power Station
But since I like to test everything, and Jackery now has a 1500-watt Portable Power Station with up to four 100-watt solar panels in a kit, I thought this was a good time to jump in with both feet and see if they live up to the hype. I also want to find out if this technology could be useful for boondocking or even during a home power outage situation.
I finally got my wife to take a picture of me with the Jackery Explorer 1500 Portable Power Station. (I’m still having trouble calling these types of battery/inverters a “generator”.) You can see in the above picture that I’ve deployed all four solar panels for a total of 400 watts of solar charging.
However, since this is now November and the solar panels were in the afternoon sun, I couldn’t quite get up to the full 400 watts of power as advertised. But 328 watts of solar charging is quite acceptable considering the angle of the sun and slightly overcast skies. Solar power is anything but constant, so you have to take whatever Mother Natures hands out.
According to documentation, the Jackery 1500 can store 1,534 watt-hrs of energy. That suggests you could run a 1,500-watt heater for 1 hour, or a 750-watt heater for 2 hours, or a 100-watt load (like a 100-watt light bulb) for up to 15 hours. That’s what I really want to know.
Can a portable inverter power an air conditioner?
The Jackery 1500 Explorer also includes an 1,800-watt pure-sine inverter that produces 120 volts AC. So it’s entirely possible that this portable battery pack could power a rooftop air conditioner for an hour, as long as you installed a SoftStartRV controller on the air conditioner compressor.
Without a SoftStartRV controller it’s doubtful that the 1,800-watt inverter could produce the 54 amperes of surge starting current needed for a stock starting capacitor on an air conditioner compressor.
Of course, the total running time with this 1,500 watt-hrs of battery might be only an hour, so this is just a proof of concept test, not something to actually run your RV air conditioner all night long. But as battery technology continues to get smaller and cheaper, I foresee the day when you could actually run an air conditioner all night long from only batteries.
Just getting started
Now realize these are all just quickie field measurements along with my own mind experiments to determine what type of further testing I might be able to perform. So in the next few weeks I’ll have more data that I can use for calculations and post about. It’s getting interesting…
New RVelectricity Forum trial run
Speaking of experiments, we’re trying out our own non-Facebook forum this week. So if you want me to do a specific test or answer a question about the Jackery 1500 Explorer Portable Power Station and Solar Panels, please click on the link below and post your questions and comments there.
And if there are any other experiments you would like me to work on, you can start your own thread on this forum and I’ll do my best to set up an experiment. That is, as long as the manufacturers keep sending me test samples to experiment on.
Let’s play safe out there….
