As I recall, the Fantastic Fans are about 3 amps each, less if you run
them at low speed. They are not much of a load on the SOLAR/Battery
system by themselves. And the freezer is probably a peak load of 6ah, I
doubt that is continuous, it must cycle by themostatic control although
it could be continuous in a high temperature situation.
The biggest concern I would have is a 2000 watt inverter, that's going
to suck down battery power at a tremendous rate when being used. Best
solution is to not use any AC powered devices when off grid and relying
on the battery/SOLAR system for power. I've learned to find other
solutions rather than run the Inverter and AC appliances because the
converter consumes so much battery power. You can exhaust your 400 Ah
battery bank usable capacity in about 1 - 1/2 hours of inverter
operation. Use it very sparingly if you must...
As to the quote, for the most part it looks good to me excepting the
installation charge. That seems high but you already know that from your
previous post. The price per panels is about right, that is about what
I paid ea for two new ones a year and a half ago. Installation hardware
and related items they have listed looks very reasonable. The SENOR MPPT
(SRSC-40/6/4 PRO) seems slightly high, I paid about $600 for a 45 amp
MPPT controller with remote digital readout module (different make) a
year and a half ago so maybe that price reflects a price increase since
I bought the one I am using.
Over all, I think excepting the installation charge, the rest of the
quote looks to be in order...
