The PD 92-series converters all have the charge wizard built in, which is how they differ from the 91-series converters. It may or may not have the external remote box with the blinky light and the mode change button; if there isn't one attached, it can be bought and plugged in. But even without the remote, the charge wizard circuitry is included and active.
This converter should be adequate for any battery bank you could reasonably fit in. Naturally, the larger the battery bank, the longer it takes to charge (at least after a point), and in that case a higher power converter would charge the larger bank more quickly (assuming it's set to output the same voltages). For a single battery or a small bank, the limiting factor may well be the impedance of the battery limiting the charge current, not the power output capability of the converter.
The PD converters are among the best regarded ones available, by the way.
