    How any 330W panels can this system take? I see the input current seems low at 12A? Answer:
    Hi Brian. The system can take up to 14 x 330W on each of it's 2 MPPT's, so 28 panel in total. In the input current is low because you can put all the panels in series (similar to most grid tie inverters). Regards Solar Shop Support

    HiDoes this system use all of the PV power available before using grid power and will it supplement the PV shortage with grid power. (not wanting to push back into grid). Lastly if the grid fails will one still be able to use the PV array backed up by the battery ? Answer:
    Hi Adrian. The answer to all your questions is yes. It can also be programmed to do just about any combination thereof. It's really up to the user to define their requirements.. Regards Solar Shop Support.
