Logging Inquiry

[PVfish]

Hello!

I am in the process of setting up a solar energy system. I have a few questions about data logging.

Does the MN Classic only log 380 days worth of data if it is set to "Daily History" mode? If it is in "Hourly History" does it only log 380 hours worth of data? Is only possible to get a 2 second temporal resolution if the controller is always plugged into a computer using Local App? Can you export the .csv logging file to a USB flash drive at any time?

If I want to monitor the power use of my load (4 electric hoists), I need a logging device connected to my inverter. The site will not have internet, so using the MagWeb data logger is not an option. Does anyone know a way to get the power use data so it is logged locally?

Ideally I want a central logging center (computer or data logger) to monitor solar insulation data (from a pyranometer), power supplied by solar array, battery state of charge, and power use with the same temporal resolution (synchronized time stamps). Any advice on how this could be possible?

Sorry about the barrage of questions.

Thanks in advance for any help.


System Equipment:

• Eight Grape Solar 280W PV Modules (series pairs)
• Four Deka 6V 370Ah Flooded Batteries (series)
• Magnum MS4024PAE 4 kW 24V 120/240 inverter
• NE250-240 E-Panel
• MidNite Classic 150V MPPT Solar Controller

Electrical Load

• Four 750W Hoists

quick answer, I believe the only way to monitor the loads is going to be with a Battery Monitor as it will read both in and out from the battery.
