Looking for suggestions on solar controller with built in data logging

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
(voltage/current stats).

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
charge current

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.
