I want this to work all the time and be truly off grid. The guy on youtube used a Killawatt meter. No cold air escapes when opening a lid on a chest type freezer. He said if he didnt open it a lot or at all he saw this. It makes me wonder now if the freezer is not running when it wants to come on will it be able to with the inverter asleep will it wake up? I am thinking i will have the freezer right next to my inverter so there not be a need for more than a three foot extension cord and if one is needed I will use a heavy duty one like 8 gauge.� I have not bought a deep freeze yet. I want a cheap as possible one I can find used. I have been looking on Craig's list and I am wanting to find one around 50 or 60 dollars, close to my home not too terrible far to drive and it needs to be pretty small I'm thinking for better efficiency.

I just purchased two Go Power Inverters a Go Power! GP-SW2000 24v 2000 Watt Pure Sine Wave Inverter and a Go Power! 1500 Watt 24v Pure Sine Inverter  GP-SW1500-24. They are both known to be very dependable inverters. Any way I am wanting to set up off grid PV systems. I already have a couple of solar trackers with 7 230 watt panels on them. I will be making a freezer hack. I want to use a old chest freezer for a fridge because it is suppose to be highly efficient. I saw video on Youtube the guy claims it only used .3 Killowatts in a day.

GP-SW1500-24

The GP-SW1500-24 will run practically everything in your RV or cottage and still have pure power for the sensitive loads. Features include a duplex GFCI receptacle with full overload protection and power save mode. 24 Volt input with remote option.

Pure Sine Wave Advantage:
Motors run cooler and last longer
Microwaves heat in normal times
TV monitors will be crystal clear (as good as using city power)
Digital clocks keep time accurately
Medical equipment often requires pure sine wave for proper operation

I only have four deep cycle batteries for now so i may be using only one inverter for awhile until I decide on more batteries and what kind to get. I am poor so they will have to be very affordable.
I will keep everyone up to date on my progress as the project progresses.
