For the curious (i was), here's the manual for that DCM120100C monitor.

Oh, heck ... it's only 107 kbytes... here it is as an attachment: View attachment DCM120100C_-_Amp-Volt-Ah_metre.pdf
Since the one meter seems to be able to handle a bunch of shunt sizes, its calibration method seems quite complicated...
Based upon the manual, SeattleNewbie appears to have it wired correctly.
(but i'll go back and review his drawing)
**WHOOPS** found something ...gimme a minute...
You've got it wired as their "two wire Discharge" drawing (fig 1).
I'll bet a cookie that for bi-directional measurement ("Charging") your meter requires a *separate external* power supply (as their other two diagrams indicate).
Try hooking some other power source (two 9v batteries?) to their Vext pins and see if it starts noticing the Solar input. Completely separate their Vext(-) from your system. (and Vext(+), too).
Acceptable would be a 120vac to 12vdc wall-wart power supply (Goodwill has many) ... plug it into your inverter and then connect it's 12v output to the Vext pins. The inverter should provide adequate isolation.
Since you indicate **No** connection to the Sprinter's frame or battery/alternator, simply a 12v cigar plug into one of the Sprinter's 12v sockets would work perfectly. Under the driver's seat is the EK1 terminal strip with a fused "Battery +" available for "hard wiring".
