Alternator + SmartSolar charging

I would like to simultaneously charge the LiFePo batteries in my van from both my 200w pv panel controlled with a smart solar75/15 and the alternator via an Orion 12/12. However, I’m finding that the smartsolar always goes to Float shortly after I start driving and the alternator kicks in - even with soc at 50%. Is there any way to avoid this?

Had the same experience, but the other way around. Battery absorption and float settings must be identical in both. Also check the solar charged voltage, detection time and tail current. If they're still at default, tweak by lowering tail current and increasing the other two.
