Need Help with Solar setup

[Westbranch]

Tell us where each of these components are to be located....  How far apart and where are the batteries in relation to the rest??
Oh , why 2 60A CBs? and is it one or 2 strings?

Panel side and battery side breakers on the C150?

Just my first thought.

...  Mine too.... but I suspect he would need a 125A min for the batt to Inverter/CC based on proposed loads, and for PV he would need 10 or 15A per string for ease of disconnect , even though  not needed by CODE  if only 1 or 2 strings... and 60A for the Classic..

So, does this look like a decent startup build? And am I missing anything crucial? (wiring, cabinet fittings, batteries, etc not listed)

Aims 1500 Watt pure sine inverter                                      $279.00   1   $279.00
Canadian Solar 320 Watt Poly Solar Panel                      $185.97   4   $743.88
100 Foot Black & Red 10 Gauge MC4 cbls                        $84.99   1        $84.99
Midnite Solar Battery Capacity Meter, Model# MNBCM        $63.00   1     $63.00
150vdc breaker 60 amp                                                        $20.00   2     $40.00
combiner box - Midnite Solar MNPV2-MC4                      $149.00   1   $149.00
charge controller - Midnite Solar Classic 150                      $568.00   1   $568.00
TOTAL                                                     $1,927.87

That would be an incredible deal on the PV  - you sure that is the price of a 320 watt panel ? That is only 58 cents per watt.
You don't need that Midnite Solar Capacity meter you listed. You need a Whizbang Jr and a shunt

These will let your Classic tell you the state of charge and do some other features too in controlling loads and charge termination .

This is the combiner box I would get - plenty of room for future expansion if you want to do it . And as others have said you need 15 amp breakers for each string

These are the boxes I recommend for mounting your Classic on and you can get the one that has  the correct size breaker for your inverter ( you will have to check on what your inverter calls for ) . It will be worth the price in the wiring hassles it would save you and has the mounting spots for shunt . Also has the slots to put in the breakers you need - one from PV and one for Battery and then has room for others for DC line if you want another output .

Depending on how you wire between your combiner box and Classic / Mini DC box you would probably use conduit from combiner to MiniDC and use regular wire in it . For the connections between PV and combiner box you can get a piece of PV outdoor rated wire and just get the connectors you need to match your panels and put them on . Since you would be adding on in the future might as well learn how to make up the cables yourself .

Use these at bottom of combiner box to stick PV  wire through for sealed connection .

This is what I have used in the past and recommend.

Look up the wiring schematic for the Mini DC box on the Midnite site and you will see how the wiring goes . Ignore the dotted box on the schematic that says GFI since you probably don't need that .
