Charger selection help please
I'm thinking about buying a Noco Genius G26000 26a smart charger for when the sun isn't getting my batteries charged. I have a FR Stealth Toyhauler with two Interstate GC2 208ah batteries. They do...

With no solar, let the batts run down until your "morning voltage" is 12.2ish. Then do a 50-90 on gen and get as high in SOC as you can after that on solar till dark.
You don't have to recharge every day. The batts will recover to 100% next time you have shore power or some longer times with good solar conditions.
Note--
A.you will not be recharging to 100% on generator, just to 90% unless you are crazy :)
B. You can rig any deck mount converter as a portable charger simply by using a set of cut-off jumper cables (4 AWG though--not those skinny wire ones) in the terminals with the clamps to go on the battery bank (that's what I do with my 75ADJ )
I have a 48v system at my off grid place with 370ah Trojan RE batteries. I rarely take those below 80% SOC and hope to get 12 years or more from them. They are not cheap batteries. I guess that's why I like to charge every day in the trailer. On the other hand the Interstates are cheap at Costco and I'll probably spend more on gas than replacing them more often.
I'f I'm only going to 90% SOC when using the generator then the Noco can surely do that. On the rare occasion that I have to use my generator at my cabin I go to 90% and let the CC take over the absorption and finish.
