I agree that it is better to build your own system.... so much
more for so much less.... At 50% discharge of the battery
(65AH x 12 V = 700WH + ) you would have a more robust
system. However, a bit more solar
capacity would be required
to fully charge the battery it you routinely used 50% of its

100 Misc wire and parts
The above prices were found without too much shopping
around. Lower prices can be attained with patient shopping..
My system ran about $800.
I have been using a similar setup for years and it has never
failed to provide enough power for my boondocking
sun is blocked for several days. I run basic trailer LED lights
Computer, phone charging, ham radio, satellite radio, coffee grinder,
juicer, etc. My rig has no microwave
and the refrig does not
have electronic control... Just a little ventilation fan that runs
constantly on warm day using about .4 Amps.
It is interesting to note that these self built systems can
provide more performance at a lower cost than the ready made
systems. If you can live without your system talking to your
smart phone you might be satisfied with one you build yourself.
Also, consider the educational opportunity building your own
charging system would provide...
Of course, if you can't or don't want to take the time and effort
to put together your own system, a ready made system might be
better if you can live live with the reduced performance and
Good Luck, Larry H
