Call MorningStar and ask their technical support rather than basing your
decision on what people in this forum think. I've found their support to
be very helpful.

I have 6 solar panels producing a total of 3,84 amp (.64x6). I want to
install one additional panel of .64 so to produce 4.48 amps. I am
concerned if the solar regulator will handle the additional amps. Here
is the information I have on the Morningstar regulator:

Rated Solar Input: 4.5 amp
Max Input (5 min): 5.5 amp
Short Circuit Rating: 5.5 amp

My solar capacity of 4.48 will be very close to the regulator stated
capacity of 4.5. Is this dangerous? If such is the case and since I
can not afford a bigger regulator at this time I will not get the much
needed additional solar panel. The solar panels are permanently
attached to the deck and it is unlikely that all seven panels will be
simultaneously exposed to full sun light. But it can happen. I have a
430 amp battery bank.

Please let me know if it safe to go ahead and install another solar
panel of .64 amp without changing the regulator. Thanks for your
wisdom. Roy )
