Question 1: In the BYD example diagram (shown), in wiring unlimited and several other sources, it is mentioned that the negative battery pole should be grounded. In this case the BYD battery has its own grounding point, is this just the casing, or is that the negative pole? Do I need to ground the negative pole in addition?
Grounding such a connection will damage the product. The AC ground terminal of all inverters and inverter/chargers is connected to the chassis. The neutral of all inverters rated 1600VA and above and the Inverter Compact 1200VA is connected to the chassis. Grounding the chassis will therefore also ground the AC neutral.
In case of battery negative grounding and multiplus primary ground (chassis), information advice you to use same size that dc main cables as you suggest in no. 1a (or fuse rated). But which cross-section you suggest for the one earthing point to stake/rod/connection from the main grounding busbar? eg.

Question 1: In the BYD example diagram (shown), in wiring unlimited and several other sources, it is mentioned that the negative battery pole should be grounded.
Use one ground only, close to the battery. The battery poles are supposed to be safe to touch. The battery ground should therefore be the most reliable and visible ground connection. The DC ground cabling should have a sufficient thickness to be able to carry a fault current at least equal to the DC fuse rating.
System grounding Ground or earth provides a common return path for electric current in an electric circuit. It is created by connecting the neutral point of an installation to the general mass of the earth or a chassis. Grounding is needed for electric safety and it also creates a reference point in a circuit to which voltages are measured.
