In a battery based system, it is recommended to connect one of the current-carrying conductors as close to the battery as possible, as the battery is typically the greatest DC source of power. *As with chassis grounds, one reason to ground the electrical system is for safety; however, electrical transients are another major reason.*
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.
Grounded systems are dangerous and unreliable. At this voltage and power level it is not required to ground the system. What is important though is that there be over current protection. So if you are not grounding the system you will have to add protection devices to both polarities. the system is grounded.
Regardless of grounding polarity, battery energy storage systems need to have floating grounds as a critical safety component. That is where galvanic isolation is used. Galvanic isolation is useful in solar projects where electric circuits must communicate but their grounds are at different potentials.
Solar and battery storage make such a natural pairing that it’s becoming surprising to hear about a new utility scale solar project that isn’t incorporating batteries.
There are three main reasons for grounding in an off-grid power system: safety, voltage transients, and the sheer fact that they are required for some loads. But before we address each of these, it’s important to understand the actual definition of ‘ground’. There are two types of ground: chassis (or mechanical) and electrical.
