Love the pin connectors that came with the charger. like TE Connectivity 736013. Anyone know a source for these?

Yes, it is a simple AC plug 3 prong version.

Does this unit provide clean, rf am radio interference free, 12vdc?

These units will not interfere with this unit at all. There have been no complaints about radio interference.

The manual states the 1250 is for a bank of 500Ah max. Will it work well if an 875ah bank will never be discharged more than 500ah?

There should be no problem. It just takes longer to charge the larger bank. These units have been in use on 800ah banks without issues.
