I've pretty well got the arduino system tested and working, just need to do some test witht the inverter in the system.

I was just looking at the specs, and I saw the PV power limit..
Electrical Specifications:
Grid-inverter Type 500W
Recommended Maximum PV Power Ppv=720Wp
DC Maximum Input Power PDC.max=600W
DC Maximum Voltage VpvDC30.2VDC
PV MPPT DC Voltage Range Vpv 12.5V~28VDC
Peak Inverter Efficiency ηmax>94%
MPPT Efficiency 99%
PV Maximum Input Current Ipv.max30A
I'm just wondering how the MPPT 'brain' handles being connected to a battery bank??
It seems like a big 24V bank would appear like an almost unlimited
amount of PV is being used.. Unlimited current..?.
I know that a couple of old car batteries can pump out way more than 720 watts of power..
Will the MPPT try to suck those batteries bone dry?
