[RE-wrenches] graphic software for mac

[Jonathan Hill]

Dear fellow wrenches-
I'm looking for a good, simple drawing program for mac. I need it for pv system layouts. Free if possible. Any suggestions?

>>> This just came up for us recently. I learned this, surprisingly, from a Customer Generation tech at our local utility. We are installing a GTWB system with two SI5048s and two SB5000s. The CG tech spoke with SMA tech support about the possibility of the SIs selling back to the utility as well as the SBs. He learned that there is a software patch that can be installed in the SIs that will allow them to do this, but that SMA will only allow the patch to be installed upon receiving written permission from the utility. This was sufficient for our utility to consider our system to be a 10kW interconnected system.
