PD4655 Charging Graph
I have been reading quite a bit about different converters and charge rates, specifically some claims that PD's seem to drop off earlier than other brands. That is not what I have noticed on my setup,...

In all the years I've spent charging car batteries, not necessarily Deep Cycle batteries, my observation has pretty much been that if you take the chargers Amp output on a meter, what it is capable of putting out on a low charged battery, say for example 10 amps, you can take 50% of that amp capacity the charger is capable of putting out, ie, when the charger is only putting 5 amps in the battery, and you are then pretty much at 90% state of charge when the charge rate drops to the 50% of capability of the charger. This has pretty much held true, whether a trickle charger, a 2 amp/ 6 amp charger, a 10 amp charger, and battery sizes from slightly smaller than group 24's to group 29 sized batteries in cars.
I can't be certain on high antimony batteries like CG-2's and Trojan T-1275's, industrial grade batteries.
So if your PD 9260 is putting out only 30 amps with the clamp meter, there's a good possibility you are 90% charged, and can shut down the generator and go to solar for top off charge, if you are solar capable.
Of course, that would be about 22.5 amps showing with a PD 9245, and 15 amps showing if a PD 9130.
YMMV. Wire gauge makes all the difference on these charge controllers.
