The only time you need a 2000 plus inverter is for big appliances such as microwave, blender, electric Heaters......ect - you know popcorn can be popped on a stove, barbecue.... 😜😜😜 besides microwave or such will draw down your 4 batteries very fast, with a 3500-5000 I'd have at least 6 12V batteries.

To Run Satellite, TV, Stereo and LED lighting all night long for couple days a 1200- 2000 watt would work great on 4 12V batteries - charge w solar or generator definitely research panels - output Amps is important for re charge time. Also how efficient the panel are - some panels lose more than 50% charging capacity if not align to the sun correctly

I ran a 1500 inverter for years in my last RV --the biggest gain in time was when LED lighting came out huge difference in battery consumption.

Some generators have an optional battery charging kit - which helps recharge your batteries much faster too.

I'm just doing the research again - solar panels and inverters have changed a lot in 5 years

And the shore switch is the way to go as others have stated

Good luck

2000w inverter runs everything just not all at once fused at 300 amps and with a disconnect. Run with 4 6v golf car batteries 4/0 wire and transfer switch into sub panel that powers all outlets except one. LED lights a big help. Inverter near the batteries and batteries in a naturally vented box. (I used a Walmart truck tool box, almost perfect fit with some tweaking). 300w mono solar panels with MPPT controller. And a 2500w gen for an occasional boost.

PH . yes micro will draw down fast but only on for a few mins at a time .I think the 800 watt inverter should run my 120 watt tv and blue ray player or hopper . since our units will run on DC all but the fridge and microwave . I think i just need it for the entertainment center. have the generator for charging the saving propane during the day . when at the koa full hook ups but want to get set up for no hook ups and last weeks

435ah 12v battery bank Vmax Charge Tanks, 2000watt Cotek hard wire with transfer switch, 520 watt solar array, Morningstar MPPT TS60 charge controller, all remote monitors and fusing, about $2500 or so in my project. Works very good!!! Pic in my album if you'd like to look at them.

Your installation looks very clean. Great Job...

What are your thoughts on the Vmax 155 AH batteries?
Only draw back is weight but I believe they are one of the best AGM batteries around. Batteries are the last purchase for my solar setup.

You should determine your actual energy usage first then you can size your battery bank, then divide the battery bank ah by 2 and that will give you the total ah available. Then you can determine inverter size based on your projected ac load.

I have 2 of the SLR155 and 1 of the SLR125 I like them so far. I think a good charge controller is also key. Your solar array size you will want 5% to 10% charge capacity of your battery bank. So Mine at 435 X .05= 21.75 amps so I'm at about 6%. I have monocystilline panels.

One thing no one mentioned is, if using for electronics like BR player, flat screen, etc., you should get a pure sine wave inverter. They are much more expensive but the way to go. Go Power has a good blend of value and quality. I have the factory installed roof 160 watt panel and am thinking of getting a Go Power 3000 watt inverter, matching 50 amp transfer switch, and remote monitor panel.

Cotek makes Go Power inverters and yes mine is a Cotek true sine wave, I run my 42" flat screen tv, computer, microwave, blue ray DVD, stereo, all LED lighting, side by side fridge, central heat, and all works perfectly. If you buy a Go Power open it and you will see Cotek stamped on the components. I have the hard wire with built in transfer switch. 160 watt mono panel by itself won't get you vary far with only 8 amps on a good sunny day.

You might want to reconsider the name brand of the transfer switch as I went through two Go Power switches that were both bad out of the box. Parallax builds a great switch, but it isn't small. Both of the Go Power switches I used buzzed constantly and would not switch. Check the reviews on Amazon.
