This should be suitable for 150A for distances up to 5 meters. When wiring the system, please make sure that the cross-section of the connection between the batteries and the DC distribution point equals the sum of the required cross-sections of the connections between the distribution point and the DC equipment.
Generally, 20-30 feet is the ideal distance between a solar panel, such as an array, and the solar battery backup supply. The longer the wire from the solar panel to the battery, the more energy lost in transport. The amount of energy lost also depends upon the gauge or thickness of the wire. Thicker wires lose less energy.
Battery cables are generally larger in size, ranging from 2-4/0 AWG, depending on the system capacity and the current they need to carry. Inverter Cables: These cables connect the inverter to the battery bank, transferring the DC power from the batteries to the inverter.
A DC system should always contain a main fuse. Removing the fuse will also break the circuit. So, when the system needs to be maintained or if the battery needs to be replaced, removing the main fuse will be sufficient to isolate the battery from the rest of the system. Always use quality isolator switches.
The array should be within 30 feet of the batteries, and the controller should be within a yard of the batteries. The controller is not closer to the solar panels than it is to the batteries because it will limit the power provided by the solar panels, and there will be some bleed-off that occurs naturally.
If the DC system voltage is increased, the DC current will drop, and the cables can be thinner. If you want to increase the system voltage, but there are DC loads or DC charge sources that only can deal with 12V, you could consider using DC-DC converters rather than choosing a low voltage for the entire system.

Where does the load go on this DC circuit breaker?
You could put a directional DC breaker going from the SCC output to the battery and another DC breaker from the battery to the inverter. So if you want to protect your circuit in a AIO going to and from the battery use a fuse.
How to Wire Solar Panel to 120-230V AC Load and Inverter?
This way, you will only be able to power up the DC 12V load. You won''t be able to charge the battery quickly. If there is no battery at all, You can only power up the DC load during normal sunshine / day time. In other words, without battery, you won''t be able to power up the AC or DC load during shading/night.
