Proposed Solar Install thoughts

[AlbertaNewbie]

Planning my solar install and here is what I'm currently thinking. Need opinions on the pros amd cons of my install.

morningstar tristar 45amp mppt charge controller with remote temp sensor and remote meter
250watt 24V panel (to start, will be going up to 1000w next year)
8ga wire from panel to roof mounted combiner box approx 5 feet
6ga wire from combiner to charge controller 6 feet
6ga from controller to batts with 45 amp breaker 6 feet

thoughts? anything you would change?

240 watts is a pretty large panel. Are you sure that you have a 3' X 5 or 6' long area to put it in?

You might want to try more manageable 120 - 150 watt panels.

I don't think 45 amps is enough for 1000w. (four 250s in series/parallel? ) Would be over 60a too. You could get another controller for the second string when that happens and put the two controllers in parallel on the battery bank. Must be a hefty bank!

45 amp controller won't handle the 1kW upgrade unless you are planning more controllers in parallel.
