The analogy to that arrangement is like having a stick of dynamite with a lit fuse of an indeterminate fuse length. Even WORSE, using the engine alternator to recharge a set of deeply discharged deep cycle batteries is fraught with PERIL.
DANGER!
The way I read it the AGM batteries are a waste of $$$$
The AGM vs Flooded is an argument that both sides have a strong following. From what I hear having flooded inside the vehicle is dangerous because of fumes while charging. $800 will get me 400aH for 2x 6volt AGM, I don't really have that much space so I'm going with my best option as the batteries need to be inside.
So far you have all told me I need to keep an eye on the charge levels, not going below 50% which the regulator will help with. Solar will help keep the charge but I need to look into what kind of converter I have in my vehicle at the moment.
I took a look last night quickly and it did indeed say it had overcharge protection, so that covers that issue. It's either a 1990 or 1991 and a quick google I'm seeing most have 3 stage converters but once I get back to it tonight I will take a look.
I will also need to figure out how to turn off the converter if I run shore power into the inverter.
The issue on the alternator charging. How does it charge the battery? Does it go through the converter?
Once I figure out the type of converter then I may look into getting a transfer switch.
