Hi Jason - The “d” series micros on the back of those 350 mods are from Solarbridge and probably need to be scrapped. Enphase, the last I checked, was offering their upgrade program pricing for these mods so if you contact them they will set you up with a kit of new micros and a IQ Combiner for monitoring for a good price. Then, you just wire them up like a new Enphase system.
For racking, it isn’t any problem to rack these mods up with non-SunPower racking such as IronRidge and their top clamps.
