If you can return that solar panel kit and the battery, that would be ideal.

Again, when I say that marine battery will be useless for running your loads, I mean you'll be able to run it for ~20 minutes or so before the battery is dead and takes DAYS to fully charge again (assuming each day is sunny) before it's useful again.

Also, without an Inverter/Charger (and just a stand alone inverter like you have linked to), you can't use your generator to easily charge the battery/batteries back up.

If you can return the stuff you bought so far and order different equipment, that would be best.

​

EDIT:

Here's the 'super budget build' which you can use to run some random appliances like maybe a small fridge and such, and use your generator fed through the automatic transfer switch while you're there to run the AC:

​

Solar panels:

400 Watts (Either get 4 x 100 Watt panels, or look into getting 2 x 250 Watt panels, like the utility scale 60-cell ones.)

Charge Controller:

EPever Tracer 4210AN MPPT Charge Controller

https://www.amazon.com/EPEVER-Controller-Regulator-Backlight-Lead-Acid/dp/B077HHYYHT/

Batteries:

2 x Universal UB121000-45978 12v 100AH Deep Cycle AGM Battery

https://www.amazon.com/Universal-UB121000-45978-100AH-Cycle-Battery/dp/B00S1RT58C/

Inverter/Charger:

AIMS Power 2000 Watt 24 VDC Pure Sine Inverter / Charger

https://www.amazon.com/Power-Inverter-Charger-6000W-Surge/dp/B00BXTOQD4/

​

This system will cost you about $1600 give or take. But it will be able to at least be moderately useful, and the inverter has a built in transfer switch and charger, so you can use your generator to power the AC while you're there, and then have everything just fail back over to battery when you shut off your generator and AC.

It's also somewhat expandable, which is the reason for the 24 volt nominal battery bank (and inverter) instead of 12 volt nominal.

​

EDIT 2:

Is there a bit more to your use case here? No grid power available? Is this a mobile installation? As with a lot of things, 'the devil is in the details'.

This one. Turns out it's 40A so I'm probably good.

I haven’t yet determined the charge controller. I am currently considering this 40AMP Epever MPPT charge controller : https://www.amazon.com/EPEVER-Controller-Regulator-Backlight-Lead-Acid/dp/B077HHYYHT/ref=pd_cp_86_2?pd_rd_w=RTARC&pf_rd_p=ef4dc990-a9ca-4945-ae0b-f8d549198ed6&pf_rd_r=A30ZESRECHRVT1NXREEH&pd_rd_r=376fa169-36b6-4c2a-a56d-163aa901ad0f&pd_rd_wg=JtZJ9&pd_rd_i=B077HHYYHT&psc=1&refRID=A30ZESRECHRVT1NXREEH

And the Renogy Rover 40AMP MPPT
(Two versions, I can’t tell the difference between maybe being two different years?)

I am very open to suggestions on the charge controller. The ePever comes with the voltage reader and what not, so seems like a good deal. However, through my very limited research, Renogy seems to be a standard go to.

As far as a battery, forgive me, as I am about two hundred miles south of it at the moment, but it’s just a standard deep cycle marine battery I purchased from Napa to work with a battery isolated in my old truck. I believe it has something like 150AMP charge. But it might be as low as 110. It weighs about 50lbs, not that helps anything.

Sunlight is not an issue.
