My adding inverter plans - Pls review and comment - Event Date: 29 Mar 2018

If you can make it work, more power to you. I seriously doubt your measley 150-180A even with your 120W solar would be sufficient. Is that the capacity or 50% of the capacity of the batteries? You don't want to discharge deeper than that or you risk damaging your batteries.

Upgrade to a bank of Lithium Iron Phosphate batteries at double or triple the capacity and it might be doable. Lithium batteries can be discharged much deeper without damaging them.

You would be better off getting a minimum 2000W generator for what you propose.

Agree. The amount of current required to run an inverter at 1500 watts is enormous, and would require humongous wires to support. Just 1500 watts would draw 125 amps. If you should happen to put a 3000 watt load on it, it would go to 250 amps. Now you're talking about welding cables.

Even a 1500 watt load would deplete your 150 AH batteries (if you have two of them) in less than an hour. The usable capacity of TWO 150 AH is about 1800 watt-hours. That means you can run 1800 watts for 1 hour, and then you are done. 

premix and freeze the margs in the pod freezer and cook on the stovetop or charcoal grill.  That sounds like a lot of work for 15 minutes in the nuke box and a blender.  

Nothing much to add -- if solar is your only means of recharging your batteries you're going to be SOL after one cloudy day.

I have and really like the Yamaha 2400iSHC.  You can spend less but you can't get much quieter.  It runs my air con and microwave, but not at the same time.  For what you'd spend on that inverter, you can have power anytime for not a whole lot more.  If you don't care about the noise you can get a generator for a good bit less than that inverter.  And you will have to spend some bucks on cables.

Listen to what folks here say.  I really don't think you'll be happy with that size inverter for very long.

Battery voltage must be measured unloaded and after a resting period. If you get to 10.5V under these conditions your battery is totally dead and probably damaged. Most sources indicate 50% SOC is 11.9-12.0V.
