Mean Well power supply for my usage
I've been reading old threads for a couple of hours. I'm fairly sure a Mean Well p.s. can do what I want to do, but I'd appreciate if one of you early adopters can point me to a specific model, etc. ...

Like a car. You either have control of it, or you don't (back seat driver). If I don't feel like driving I don't let a 12 year old substitute. Much like letting a "Smart Converter" do all the thinking for battery charging.
If and when someone makes a "converter" that is the equal of the 25-year-old technology of the Trace 2500SB Inverter Charger, then I'd say the industry is getting places.
1. Adjustable absorbsion voltage limit
2. Time spent at absorbsion limit
3. Float voltage control
4. Temperature compensation
Folks who are weekend warriors or suckle at power posts regularly do not need this level of battery charge control. RV's that cycle their batteries down to 70% full then recharge do not need this level of control.
And I keep in mind that a few folks would rather die than admit their method of doing things did not work out in the long run, after all. Some of the claims that I read sound like the 4 lb fish that grew to 10 lbs after a few years, and fuel economy claims that no one else on the face of the earth can equal. A person cannot help but learn to take these claims with several grains of salt.
Batteries that routinely see 50/50 cycling are in a different universe than batteries that see 30% discharges, or occasional 50% discharges. Even a week or so is not long enough to allow batteries to display their inner sometimes psychotic behavior. In short someone who routinely discharges batteries 20-30% overnight then quickly refills them the next day with generator and solar power hasn't the faintest idea of how their little monsters will react if forced into a 50/50 march for weeks at a time. More demanding yet is a 50/20 or 50/30 charge routine with occasional bouts to make up the missing 20-30% of amp hours.
At home I am mostly fortunate where I can float my 28 volt system and play with float finishing voltage. But when a storm or hurricane comes long and knocks power out for a couple of weeks, I have to change the routine totally and completely from an overnight or day long outage. Twenty-two years is a long time for a battery to last. If they had seen regular 50/50 operation I'd bet the lifespan would have been cut in half.
A Honda engine coupled to a tiny 70 amp alternator like an ND would make a formidable battery charger. Where a standard generator may struggle to power a 40 ampere charger, the 70 ampere alternator load would be a breeze. It's all about efficiency.
