You have power?
As of today, NO!

 

Generator time.....

 

Yup!

 

I never lost power other than everything flickering throughout the storm. My internet on the other hand went down well after the storm finished and remains down now for the 3rd day.

 

Still out.

 

Nothing yet!

 

Still out.

 

Think it was yesterday morning saw a national tv interview of someone in Connecticut that had downed wires, poles, trees leaning on wires, etc and he was saying they hadn’t seen anyone from the power company.

looked like it was in a suburban neighborhood (vs way out in the country somewhere)

 

FINALLY!!!!!

 

Hello, I didn't lose power either

 

I am new to the industry (about 4 1/2 weeks), just got my truck last Friday from : [https://wattinsider.com/best-inverter-for-truck]. I was told it might have a 1800 watt inverter in it turns out it doesn’t. I was given a 300 watt inverter with a deep cycle battery so I can run my CPAP machine. I was told to only run the CPAP off it. I was thinking of maybe just repeating the setup on my own, buying a battery and inverter. Things I am looking to run are a TV and PS4, I have an electric kettle and air fryer, also looking at a 12 volt cooler and also an induction hot plate.

Questions:

1. What ,if any, of the above things can be safely run off the 300 watt inverter? It is connected directly to the deep cycle battery.
   
2. What size inverter do I need to run the things on the above list, I read that the kettle and Air Fryer take about 1800 Watts, seems like heating requires a lot of juice?
   
3. Can I run a large inverter (2000/3000 Watts) off one deep cycle battery? If so how long should I expect it to last between charges. My plan was to alternate days: charge company battery one day/my battery the next.
   
4. Do I need a specific type of deep cycle battery, I’ve read marine battery’s are better for this type of thing.
   

 

Good Taco Tuesday morning Charles.
Your question is a little more complicated to answer. The basics is power consumption of a device in watts. If the device does have the Watt rating listed, the formula is;
Watt (P) = AMP X VOLTS
(W = A X V)
(P = A X V)
P = 3a X 110v
P = 330W

So with a 300w inverter you could not run the device is the above example!

Yes anything the has a heating element will draw large amounts of power.

2-3K inverters can be ran off of a single Deep cycle battery but a standard marine battery will only run for a short time. The larger the inverter the more Amp Hour draw. The more load on a 2-3k inverter will draw more power from the battery to maintain the output!

Now to batteries.
Standard Lead Acid car batteries are not designed to be depleted of more than 20% or below 10.5 volts. You can typically get by doing this once or twice but you run a risk of Irreparable damage. Automotive AGM are about the same in maximum discharge but you can squeak by with a few more heavy discharges.
Marine batteries or Deep Cycle batteries which is an incorrect label can take a heavier repeated discharge. But the are not designed to be fully depleted and must be fully recharged within 12 hours of damaging sulfation will occur! Again AGM will take a slightly deeper discharge.

Now we get in to Solar batteries. The are designed to take very heavy discharge and recover with less chance of damage. But even they can be damaged by too much discharge and not recharged soon enough. But they are about 2-4 times the price but have a much longer life!

As a general rule, a standard car battery (the gold or top of the line) will have an amp hour rating depending the group size of 65-100 AH. That means a device that draws 1a could be ran on a 100ah battery for about 20 hours! That is a generous rule of thumb! Then the battery will need to be recharged fully before being used again!
But if you had Two 100ah batteries hooked in parallel (positive to positive and negative to negative) that is 200ah and Theoretically that would let you run that same device for 40 hours.

Again the is no simple answer to you question. There is plenty of information out there about backup battery/inverter use and builds. Look up building a "Solar Generator" (which is a bad name for a portable power supply) and there is plenty of info about that.

I am on a Satellite phone and internet connection. I use two 110ah automotive H7-AGM and power a 400w inverter. This lets me run the Satellite and Phone for about 4 days with about 25% discharge. We do not run them after we go to bed. So 24hrs X 4 days is 96 hours. the system is turned off for 8 hours a night for 4 days, or about 32 hours. 96-32 = 64 hours of run time!

Hope this helps. I know it is long and somewhat confusing.
