The JASPak Solar Generator Power Plan

You must have a plan!

Because you are here and planning to invest in a JASPak Portable solar Generator, you are already aware of what may happen in the future! You already have plans for your family, your food and your security. Electricity is one more step in your plan and the JASPak Portable solar Generator will be the only solution you will need!

To get the most out of any resource, you MUST have a plan on how you are going to use that resource. The JASPak Portable Solar Generator team wants to give you this headstart on a plan for using electricity with your generator. Knowledge of your capabilities will help you make better decisions and bring a level sanity to any crisis or emergency situation.

Step 1:
What is going to be necessary to power, and what is going to be nice to power?

Necessary will likely be:

  • Medical equipment like oxygen machines, CPAP machines or blood pressure monitoring
  • Refrigeration for medicines or food
  • Charging of mobile phones for emergency communications

 

Nice will likely be:

  • Fans
  • Entertainment like TV, Radios and DVD players
  • Lighting
  • Computers and tablet devices if internet is avialable

Step 2:
How much power does each resource require and for how long?

Typical wattage will be:

  • Oxygen concentrator ~ 150 watts per hour running continously
  • CPAP machines ~ 50 watts per hour running for 7 hours of sleep
  • Blood pressure monitor ~ 15 watts occassional uses of 1 minute
  • Refrigerator ~ 120 watts running for 1 hour, then off for 1 hour (12 hours/day)
  • Charging of mobile phones ~ 5 watts for 1 hour per day
  • Box fan ~ 75 watts per hour of runtime
  • 26″ LCD Television – ~ 100 watts per hour of runtime
  • Lights ~ 60 watts per hour for 60 watt light bulb
  • Laptop ~ 60 watts per hour of runtime

Step 3:
Putting it all together

2 standard scenarios will be WITH and WITHOUT sunlight for power generation:

Because an emergency is never planned, let’s begin with the worst-case scenario on battery only operation that started after the sun went down.

Your power plan may include your refrigerator and occasional use of your television for weather and news updates. You would also like to run a small fan for comfort if it is warm. Let’s plug these resources into a power usage plan for your JASPak Portable Solar Generator starting after a storm that occurred at 8pm.

8pm – Power goes out from a severe storm. Trees are down and you could be without power for 24 to 48 hours.

8pm – From the time the power goes out, Foodsafety.gov says you have a 4 hour safety window for your refrigerator. The contents of your refrigerator should stay perfectly safe with no electricity for 4 hours and minimal opening of the doors. You have time before you need to provide power to the fridge. The JASPak Solar GeneratorYou need immediate information on storm damage and what is going on outside of your neighborhood, so the JASPak 300 Portable Solar Generator unit is turned on at 100% battery and your television is plugged in to check the news and weather. You watched TV from 8:30p to 9:00p and then shut the JASPak Portable Solar Generator down to save power.  http://www.foodsafety.gov/keep/charts/refridg_food.html

***TIP:  If you turn down the brightness on your TV, you can save significant power.  Our testing on a 27″ tube-type television showed a savings of 30 watts/hour by dropping the brightness all the way down.  Our test TV and cable box require about 50 watts/hour in this configuration.

      • Power Used from 8p to 9p: 30 watts for the TV for 30 minutes + 10% for the inverter.  33 watts (or 3 amps) used.
      • Power Remaining to 50% DoD: 73Amp-hours or 96%

9pm – It’s probably dark right now and very quiet with no electricity. After some time spent checking the house and property for any damage, you want to check the news again. The JASPak Portable Solar Generator unit is turned on again and you check the news and weather again. You watched TV from 9:30p to 10:00p and then shut the JASPak Portable Solar Generator down to save power.

      • Power Used from 9p to 10p: 30 watts for the TV for 30 minutes + 10% for the inverter. 33 watts (or 3 amps) used.
      • Power Remaining to 50% DoD: 70Amp-hours or 92%

10pm – Your neighbor’s gas generator won’t start and he is asking for help. Seems to be a spark plug problem. There is nothing you can do help. You can hear sirens in the distance and it is pitch black outside. No headlights or streetlights. You check your mobile phone to see what time it is and notice it needs charged real soon. You grab your 12v charger cable from the car and flip on the 12v outlet in the JASPak Portable Solar Generator and let your phone charge until 11pm. While waiting for your phone to charge, you roll out the 300 watt solar panel to the yard and aim it where it will catch the sunrise and begin re-charging your JASPak Portable Solar Generator at first light. Connect the cable and wait for the morning.

      • Power Used from 10p to 11p: 5 watts for the phone charger for 60 minutes + 10% for the inverter. 6 watts (or 1 amp) used.
      • Power Remaining to 50% DoD: 69Amp-hours or 91%

11pm – With your phone charged, you decide you may as well check the news one more time before bed and get the fridge plugged in so it can stay cool overnight. You run the TV for another 30 minutes, until 11:30p and then plug in the fridge.  Now, the refrigerator has been off for 3+ hours and will need to run for about that long to “catch-up”.  Our test refrigerator uses about 120 watts/hour.  It is a standard top/bottom 19 cubic foot frost-free refrigerator.

      • Power Used 11p to 12a: 30 watts for the TV for 30 minutes and 55 watts for the refrigerator for 30 minutes  +10% for the inverter.  116  watts (or 12 amps).
      • Power Remaining to 50% DoD: 57Amp-hours or 75%

7am – You left the fridge plugged in while you slept. It runs from midnight until 2am to “catch up”.  It runs again from 4am to 5am, then from 6am to 7am.  You wake up at 7am and get some nice cold juice from your fridge and prepare to start your day. You check the status of the JASPak Portable Solar Generator as it has been in use all night. Your 7am status is this.

      • Power Used 12a to 7a:  480 watts for the fridge for 240 minutes or 4 hours +10% for the inverter. 530watts (or 53amps).
      • Power Remaining to 50% DoD:  4Amp-hours or 5%
      • You have approached the 50% Depth of Discharge rule. This is recommended operation.

You shut down the outlet for the fridge because it won’t need to run for several hours.  You decide to check the morning news and plug the TV in.  You only watch it for 30 minutes, from 7:30 to 8:00am.

      • Power Used 7a to 8a: 30 watts for the TV for 30 minutes + 10% for the inverter. 33 watts (or 3 amps) used.
      • Power Remaining to 50% DoD:  1 Amp-hours or 1%

As you prepare to start the day, you have just run for 12 hours on the JASPak Portable Solar Generator!  You had television available for news and weather updates and you woke up to a cold refrigerator with fresh food!  You slept well because your generator was silent!  You have also operated your generator to the recommended 50% depth of discharge rule and have PLENTY of room to spare.  The sun is coming up and you set your panel to begin catching that POWER!

________________________________________

8am – That sun is getting cranked up and putting in 90 watts of power from 8a to 9a
9am – As the sun continues it’s rise and you track the panel, it is putting in another 150 watts of power between 9a and 10a
10am – A few morning clouds are floating about, but Mr Sun is still putting in 190 watts of power from 10a to 11a
11am – Clouds are less now and you are getting 200 watts of power from 11a to 12p

      • Power Used 8a to 12p: 0 watts.
      • Power Generated: 630 watts, or 60 amps
      • Power Remaining to 50% DoD: 60 Amp-hours or 79%

12pm – Time to turn on the fridge for a bit and check the news to see if power crews are getting to your area for repairs yet. Make yourself a nice lunch with some cold juice from the fridge and check the weather.  You run the television and refrigerator for the entire hour of 12p to 1p.  The sun is high and warm and giving you 225 watts of power.  You are running your television and refrigerator AND charging your battery!

      • Power Used 12p to 1p: 170 watts for the TV and the refrigerator for 1 hour  + 10% for the inverter. 190 watts (or 19 amps) used.
      • Power Generated: 225 watts
      • Net Gain: 55 watts back into the battery, or about 5 amps
      • Power Remaining to 50% DoD: 65Amp-hours or 85%

1pm – The fridge needs to continue to run for a bit longer again to catch up, so it ran for 2 more hours from 1p to 3p and the afternoon sunshine is giving you about 225 watts per hour. It is getting warm, so you better leave the fridge plugged in for the afternoon and not let it get too warm.

      • Power Used 1p to 3p: 240 watts for the last 2 hours
      • Power Generated: 450 watts
      • Net Gain: 210 watts back into the battery, or about 21 amps
      • Power Remaining to 50% DoD:  76Amp-hours or 100%

3pm – The fridge is caught up and shuts down from 3p to 4p and the afternoon sunshine is giving you about 225 watts per hour.  You battery is back to 100% and you can use this surplus time for charging phones/tablets/laptops/tools or watching TV or whatever you want to do.  From now, until the sun stops giving you power you can use what the panel is giving you and NOT IMPACT THE BATTERY AT ALL!  You have several more hours of sunshine and extra power!  Use it!  Keep the refrigerator plugged in until the panel is giving you less than the fridge needs.

7pm – The fridge ran from 4p to 5p and then from 6p to 7p and late-afternoon sunshine is still giving you power at about 150 watts/hour for the last 3 hours. You shut down the outlet for the fridge and let the battery finish it’s charge on the remaining sunshine and prepare for another 24 hours with out grid-power.

      • Power Used 4p to 7p: 240 watts for the refrigerator for 2 hours  + 10% for the inverter. 265 watts (or 26 amps) used.
      • Power Generated: 450 watts
      • Net Gain: 185 watts back into the battery if there was room
      • Power Remaining to 50% DoD: 76Amp-hours or 100%

8pm – 24 hours later and here you start again – at the exact same place you were yesterday. 100% battery and fresh, cold food with a television to give you news when you want it and a phone that is charged every day!

That is a power plan and that is how you will get through the storm!

 

That is piece of mind you can only get from the JASPak Portable Solar Generator!
