Nope, the PV voltage is just a tad too high. The meter max is 60v.

Okay! I just bid on some of these.. 2 Pairs MC4 solar panel connector male & female, TUV - eBay (item 250721685411 end time Nov-10-10 22:14:35 PST)
And they should be in the mail this week..

Since my panels are in series, I can insert the meter into part of the loop.
I'll probably use 2 panels, so I can cut the meter voltage in half (current will be the same).
That way, I can take data all day and then multiply the watt hours times 2..

It appears that my meter has an option to use an external DC power power supply, to run the meter..

So the data won't be lost when the sun goes down, I'll use the 12v tracker battery to keep the meter turned on, 24-7..

Hey! E-bikers are using these meters..
