Current limiting battery charger supply

[davegravy]

I have an MPPT solar charge controller which has a fixed input current limit of 5A. Unsurprisingly it's fed by solar panels.

I have an AC-DC converter that produces 15VDC and just under 5A and has overcurrent protection (hiccup mode shutdown). I need to charge the battery from this supply when it's available (and disable solar charging). I think I can manage power path with an LTC4412, the bigger question is whether I should:

1) feed the solar charger with the AC-DC converter using some intermediary current limiting circuitry so its protection doesn't trip, or
2) add a second parallel charger (without MPPT) designed with a lower input current limit, dedicated to the AC charging path. 

It's not an option to change the AC-DC converter or solar charger.

It seems redundant to have two chargers but comments like this make me think I'm barking up the wrong tree by adding current limiting. If current limiting's a viable option, are there any simple circuit options?
