I am going to be replacing the solar panels at a remote radio site
with some 130-watt Sharp panels. I have a Morningstar Prostar 30M
controller, but will need to replace as the 4 new panels will exceed
the 30 amp current limit of the controller.
Is there a controller (45 amp or higher) that has built-in data
logging? I would like to go to the site every 4-6 months and pull
stats out of the controller via a serial or USB or Ethernet connection
Any controller that comes to mind?
Thanks in advance

60 Amp Plasmatronics

Just some more detail on my requirements:
- Load current is 15-amps max
- Data logging needs to be on-board as I have no remote communications
access. I would "pull" the data by connecting a computer on-site and
retrieve data that way.
- It would be nice to have one full year of data logging storage
- Mainly looking for a daily maximum and minimum voltage and maximum

You might browse through the controllers here:
Here's an Outback 60 amp MPPT type controller that might work for you.
It does 128 days of logging and has a RJ-45 connection. They have an 80 amp
model for just a few more dollars.

I second the Outback recommendation. It's an expensive controller, but
it includes MPPT. You might also consider this

controller of your choice.
