<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: Arial, sans-serif">
<DIV>I may be out of line here, but most of these comments have been related
to making the right program settings and startup surge current issues. I
did not read any comments that this client is nuts to try and run a 3.5 ton
air conditioner from a solar off-grid system, let alone a system with such a
very small capacity. </DIV>
<DIV> </DIV>
<DIV>I would be surprised if this small existing solar array and
batteries can keep up with the regular loads like lights, kitchen appliances,
refrigerators, and entertainment equipment, let alone also running a
central air conditioner. . </DIV>
<DIV> </DIV>
<DIV>I would not just debate the problems of surge current, I would like
to know how this little solar system is going to keep up with the constant
load of approx. 4,000 watts for the AC unit plus another 500 watts for the air
handling unit which he did not mention. With a constant drain of 4,500
watts, just how long do you think this battery bank will last? For
most locations, during peak summer days a typical AC unit needs to run
constantly 12 to 16 hours per day. </DIV>
<DIV> </DIV>
<DIV>I would be interested in hearing from others on this, but here in the
humid and hot east it is not possible to provide air conditioning for an
off-grid home unless we are just cooling one or two rooms with a low energy
Sanyo type split system in the 1/2 to 3/4 ton range. Of course if you
have enough solar modules and batteries you could run anything, but can
you afford it?</DIV>
<DIV> </DIV>
<DIV>We do lots of off-grid systems and the first thing we tell clients is to
not even think about having air conditioning, electric hot water heaters, or
electric clothes dryers unless they have a really big bag of money.</DIV>
