FAQs - What You Can Expect The 4K will run any modern 25 cubic foot deep freeze 24 hours a day with power left over on an average US day of sunshine.  Take it completely off the grid, assuming average sunshine. As it sits, a 4K will run most modern home refrigerators all day and night, on an average US day of sunshine.  More efficient fridges will make it through the night with power to spare; less efficient fridges will drain it earlier and start to get warm.  Adding a pair of golf-cart batteries and a pair of panels can make it more of a sure thing; take your fridge  completely off the grid, assuming average sunshine. Refigerator power usage is impossible to predict simply because you can’t know how often someone will open the door. "So what's with this "assuming average sunshine" bit?" Your solar panels need sun to recharge the batteries, or the system gets drained and can't do anything until the batteries are re-filled.  A pair of our 200-watt panels will charge a pair of our golf cart batteries on an average day of US sunshine.  If you get storms that run more than one day, you need a somewhat larger battery bank to get through the dimmer days, and some more panels if you want to recharge quickly when the sun comes back out.  Most people want their battery bank completely recharged in one day of normale sunshine; set yours up the way you like.  More panels recharges faster, more batteries lasts through longer cloudy periods. "What do "standard draw" and "emergency draw" mean?" In your car, you have a "red line" engine speed, right?  If you keep the car below the red line, you won't damage your engine at all.  If you drive it faster than the red line, you might burn the engine a little bit or destroy it entirely. "Standard draw" is the red line: if you use the 4Kto power more than 4,000 watts of equipment at once, you might start heating up the electronics, to the point where the breaker flips and shuts it down to protect itself.  If you use it to power 12,000 watts of equipment at once, you will flip the breaker in fairly short order.  You will NOT burn it out, only flip the breaker to protect it from overheating.  You’ll lose the use of it for the time it takes to cool down. "Will my panels charge the batteries on cloudy days?" They  WILL charge the batteries, but at a lower rate, because they need bright, direct sunshine to reach their peak output.   It's roughly a direct percentage: if you get ten percent less light, you get about ten perent less electricity out of your panels, and your battery bank is charged that much less than it would be on a bright day. "The 4Konly has four panels and one pair of batteries.  Will that REALLY give me 4,000 watts?" Absolutely! For about forty minutes. What are you planning to run that will use 4,000 watts all at once?  To use that much power, you’d have to have the water heater running (2,000 watts), then go turn on every light in the house and about half the kitchen appliances - ALL AT ONCE. No one does that. Here's a thought: since it's for emergencies, how about not turning on everything in the house at once when you're running on it?   Are you really using 4,000 watts?  Almost no one ever does.  it's VERY difficult to do in a home setting.  The less power you're using, the longer the power in the battery bank lasts, just like the gas in your car's gas tank.  Then it will take the panels about a day of average US sunshine to refill the batteries, after which you can do it all again.  Don't let other companies' misleading advertising mess with your mind: nothing is free, and solar power isn't cheap.  However, solar power IS as reliable as the sun, and we've used the most solid electronics, cables, batteries, and connectors available to build longevity and reliability into the system.  This system CAN be expanded to get you completely off the grid, but all our customers so far have bought it as insurance against the failure of the grid (predicted by both NASA and NOAA). "How long will the 4K give me 4,000 watts?" How many charged batteries did you hook up in your battery bank?  Heavy work requires lots of "fuel."  How big's your “gas tank”? As it's configured from our factory, the 4K will give you 4,000 watts for about 40 minutes. "That's not much," some say. "Really?  What are you going to do that needs 4,000 watts?  That's like driving your car with the gas pedal on the floor, doing the full 125 mph or whatever it may be capable of.  How often do you actually do that?" we ask. "Huh?" they say. We ask, "What are you actually going to run all at the same time? The bulb usually goes on right about here.  "Oh...at once?  A fridge, a chest freezer, a couple lights, a computer...that's about it." We do some addition in our heads, and say, "Okay, a fridge is normally about 800 watts, and runs about five minutes every hour.  A chest freezer normally uses about the same, but runs even less.  Lights are normally 75 watts and occasionally 100 watts, and a computer about 400.  Add up the lights and computer, and you've got about 600 watts you're using constantly.  The fridge and freezer use about 800 watts for about 4 hours per day altogether, or 3,200 watts for an hour - 3.2 "kilowatt hours."  You may have seen that word on your electric bill; it's how electric use is measured and sold. Now let's assume you use the computer and lights eight hours a day; that's 600 watts for 8 hours, or 4,800 watts for an hour - 4.8 kilowatt hours. So in this scenario, you're using 3.2 kilowatt hours every day for the fridge and freezer, plus 4.8 kilowatt hours every day for the other stuff, totalling 8 kilowatt hours of electricity every day. To provide that on an average US day of sunshine, you need about 3 pairs of our golf cart batteries and six of our 200-watt panels to recharge them.  Sunshine varies; brightness is not the only factor. Since the 4K comes with one pair of batteries and four 200-watt panels, to reach that goal you'd need to add two pairs of batteries and two to five 200-watt panels, depending on the sunshine in your area. See how it works? Whether you expand your 4K System with our products or someone else's, we want you in control of your power.  That means knowing how to figure out how many batteries and panels you need, which we've just gone over here.  It also means knowing how to connect additional batteries and panels, and our user manual tells you that.
