Is my inverter/charger large enough?

[MambaJack]

So purchased an inverter charger from a local distributor to charge my 24v 470ah battery bank. (8 @ 6v 235ah)
They advertised it to me as a 40amp charger, but turns out it is only 30.
Would this give me enough amperage to charge the batteries?
The guy is telling me the only difference is the time it takes to charge?

Eventually I plan to put solar on my bus to charge the bank.
When i looked into that before, I believe it was recommended that i get a 24v 50amp mppt charge controller to get the charge rate i needed.
Should it be the same charger from shore/generator?

Thanks!

30A charger will work. Flooded batteries would want about 10% of capacity, for decent charging, si it's a bit undersized, but better than nothing Best would be 45A - 60A charger
Getting a 120V outlet to power that is going to be rough. You may have to use a 240VAC charger

Best way to charge from bus, is to buy an auxiliary bracket for a new 24V alternator and bolt that into the engine. 24V 50A alternator is large enough.

A 30A 24V solar charge controller will barely work. It will want at least 900W of PV to deliver that to the batteries. Good luck fitting that much solar onto the roof.
1500W of PV woudl be better, because it will never be well aimed, but that will never fit up there, unless it's a really large bus

Thanks Mike. He says he has a 40 amp version. But it comes with a 3k watt inverter. Would that be better then? I have 00 cable for the battery bank

Before you get other charging sources set up, how deeply will you be discharging the batteries ?

[MambaJack]

my plan is not to go below the recommended 50% for fla

They guy at the store called me back and said that both would do a fine job charging. The 30 amp 2k watt that I have will take 8 hrs to charge half way and the 40 amp 3k watt version would take 6 hrs to do the same. He did say that the 3k version had 2x the idle consumption than the smaller version
