Grounding. The nominal battery voltage in these systems is 48 V DC. The operating voltage may be as high as 62 to 65 V. Normally the multimode inverters do not ground one of the battery circuit conductors and the NEC requires that one of the battery circuit conductors be connected to earth with a grounding electrode conductor (690.41).
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 …
If you connect more than one or two 400W portable solar panels in series, the total output voltage will exceed 12V, and you''ll blow a fuse (at best). However, many grid-tied and off-grid residential solar power systems require high voltage, which can''t be achieved by wiring in PV modules in parallel.

How to Connect Ground Wire to Car Battery? Now that you know the proper place to connect a ground wire to the car battery, it is time to know how to connect it. We will present a step-by-step procedure to connect a ground wire to the car battery or simply to ground the car battery. The process is divided into two parts. Let''s begin.
A grounding wire of 6 AWG must be connected to the grounding terminal on the inverter and connected to a single-point grounding connection wire. If there is no suitable grounding connection point, then the grounding wire from the inverter must be connected to the negative terminal of the battery bank for off-grid systems.
The grounding point of the inverter is connected onwards to the grounding system or grounding electrode of the residential facility or building (see figure below). 15) PV circuits having 30V or 8A more shall be provided with a ground-fault protection device (GFPD). Nowadays, in general, this is a built-in function of inverters.
System grounding. To limit the voltage induced by lightning, one conductor of a 2-wire PV system operating at more than 50V must be solidly grounded (connected to the earth) per 250.4(A)(1) [690.41]. The grounding connection can be at any single point on the grounded conductor of the PV DC output circuit [690.42].
