Be carerful with all electricity. I was retrieving a 48v golf cart from a pond after it had been submerged for 5 days. The seat had floated away and my hand passed about 12 inches from the positive terminal while I was grabbing the frame with the other, while I was chest deep in water. Strange sensation. Leaking acid? No, that doesn't feel like acid. So I moved my hand a little closer and it got stronger. It was actually such a strong feeling about 8 inches away that it would have been one hell of a shock on contact. The batteries measured 51 volts, still had air space, and were totally undamaged by being underwater. I've heard of 50v killing and I'm certain this is a situation where it could. I received one hell of a 50v shock from a phone line while laying on my belly in a damp crawl space too. Soaked hands grabbing chassis ground and positive 50v certainly would have been worse. Now that's only 50v. What's the voltage of these chargers? Pond water is full of electrolytes and can carry enough current to kill. Electricity has a ranged effect in it, and touching even a low voltage source while wet with pond water will really get current into you.
If batteries are the heart of your system you have lots of problems anyway. Unfortunately the batteries are the most expensive, most complex, and most maintenance intensive part. Solar is a better match for charging batteries at the C/8 rate (8 hours to fill, 4 hours from half charge) which is best way for a flooded lead acid battery. A charge cycle will have the generator running for 4 hours whenever the batteries hit half-charge, and you still need inverters and all the other crap. If batteries are going to be your main power source then solar is actually a really good option, geography permitting. Having big batteries and inverters allows you to right-size the generator to some extent down towards average load, and that's good. And you'd want this anyway because you really can't repeatedly charge batteries too fast.
I used to run solar in an RV. I lived off of it. I know how to design a solar system and the first rule of that is to take what you need and then at the very least double it. A system that has panels, batteries, and a generator might actually come in the cheapest because you could actually right-size everything and run the generator very rarely and shoot for a 20 year TBO on runtime. You'd use less fuel, fewer panels, and fewer batteries, and you'd have much more redundancy. tldr; solar is good.
Now the standard library will be rewritten leading to a bifurcated Dual Monarchy under the Googleburg Empire. Only time will tell if the House of Google is strong enough to hold together as one peoples of such different worldviews.

This happened because the Anglo-German alliance never got off the ground.
