Hi everyone, I'm brand new here so apologies if this has already been asked or is in the wrong section. Fwiw, i did try the search function.
I'm very new to solar in general, I have only one success that is a small off grid system for a shipping container I use frequently. But this question is about something I've been thinking of throwing together. I have a leftover panel from our business (435W, 72.9V, 5.97A) and I'd like to turn it into a kind of emergency backup system I can wheel out if we have a week long (or more) power outage. Bear in mind this would be just to keep a few essentials running like fridge, chest freezer, and charge some phones, headlamps, etc. My thought is to make a cheap version of something like the ecoflow Delta pro type products where I have a couple (few?) batteries and an inverter strapped to a dolly or something, I can wheel it out, plug in the panel, charge controller, and a couple essentials, and be a hero because the taquitos don't go bad. Of course if this doesn't work or the weather is bad, outage extended, whatever, I have a couple gas generators I can use to supplement or replace.
Finally arriving at my main question: what considerations, if any, do I need to have due to the higher than normal voltage of the panel? Are 12v batteries still ok? Standard 12v inverters still ok?
And lastly is there anything else I'm missing or is this just a bad idea in general?
Thanks in advance for the help guys!
