Don't use the low cost breaker shown, they are unreliable.
I posted a schematic diagram, follow that.
Before you do anything else, disconnect the negative wire at the battery. Reconnect this last, when the rest of the DC circuit is complete. This will prevent accedental shorts whilst working on the system. If at any stage you wish to make alterations , isolate the solar then battery. Reconnect battery first then solar.
Putting a circuit together is not following pictures, you need understand the resion for each wire and component part and how there are connected.
Follow my diagram and let's consider the battery.
The battery positive connects to the positive buss bar via a 'master' battery fuse and optional isolator. The battery negative (disconnected for now) connects to the negative buss bar. If the optional shunt (for battery monitor) is used connect as shown
Now the inverter, its 2000 watts, 12v. The inverter negative connects to the negative buss bar, the inverter positive connectes to the inverter fuse, then via a very short cable to the positive buss bar.
The MPPT battery negative connection connects to the negative buss bar, the positive connects via a fuse and a very short cable to the bositive buss bar.
The distribution fuse box common negative end is connected to the negative buss bar, the positive to the positive buss bar, again via a fuse.
Consider fuse values and types.
MPPT fuse, as its a 60 amp unit, use a 70 or 80 amp , midi link fuse with holder
Auxiliary fuse box, typically you wont need more the 50A for DC accessories, use a 50 amp Midi fuse with holder.
Inverter fuse, 200 watts at nominal 12v is 170 amps , use a 200 or 225 watt fuse, ANL or Mega with holder.
Master battery fuse, the maximum current will be in the region of 250 amps or lower if the battery has a BMS. Use a 250 amp
MRBF fuse in a Blue sea holder, bolts on the battery post.
Once all this is connected up , check carefully the wiring matches the schematic diagram.
Now energise the circuit by connecting the negative wite to the battery post. ( and turning on the battery isolator if fitted.)
At this stage the Inverter and 12v ancillaries should work, and the MPPT should show signs of life.
Now consider the solar. Connect the panel string to the MPPT an isolation switch in series with the positive.
Cables have not been considered. Estimate the maxinum current and select the the cable from this chart.
