The Marey gas tankless water heaters can accept preheated solar water. There are controls on the front of the Marey 5L, 10L and 16L units that can be adjusted to accommodate the higher temperature incoming water. You would want to set the temperature knob and flow control knob to a good desired temperature. If the outgoing hot water is still too high then a thermostatic mixing valve may be installed right after the heater.
Below are the models that support solar preheated incoming water:
Marey GA5LP (Liquid Propane)
Marey GA5NG (Natural Gas)
Marey GA10LP (Liquid Propane)
Marey GA10NG (Natural Gas)
Marey GA10LPDP (Liquid Propane)
Marey GA10NGDP (Natural Gas)
Marey GA16LPDP (Liquid Propane)
Marey GA16NGDP (Natural Gas)
