Grounding Kc 120 Solar Panel

To be clear we are always floating the leads of the solar panels never tie panel lead to earth ground other through a dc surge protector if used.

Grounding kc 120 solar panel.

When installing a solar photo voltaic system pv it is extremely important all the equipment is grounded correctly. This junction box located on the back side of the module is weatherproof and is designed to be used with standard wiring or conduit connections. Chassis or mechanical and electrical. It also limits the voltage to ground that can occur on normally non current carrying metal components ranging from frames and rails to conduit and enclosures.

There are two types of ground. Even if you seldom have electrical storms all it takes is one lightning strike or a single lose wire and all the. Safety v oltage transients and t h e sheer fact that they are required for some loads. Long driven into the earth.

Failure to ground the entire system to include all the individual pieces can be devastating especially in an area that experiences lightning on a regular basis. Sub panels are grounded through the cable that provides the sub feed circuit power. Even if you are a good candidate for a rooftop solar energy system there are many benefits to choosing a ground mounted solar panel system. The ground bar is bonded internally when an external bond to earth is installed as described at the link for electrical grounding below.

From a lightning control point of view there is probably little reason to connect a 6 awg cable from the mount ground rod 100 to the house ground rod after the fact. This is a minimum procedure in an area where the ground is moist electrically conductive. Where the ground may be dry especially sandy or where lightning may be particularly severe more rods should be installed at least 10 feet apart. As shown in module mounting specifications all of the kc modules utilize the type g junction box except the kc 70 kc 80 and kc 120 1 modules which utilize the type m junction box see j box details.

First ground mounted solar panel systems are very easy to place because they can be located on open land. Grounding a sub panel. Leave around 6 above ground to properly attach your copper wire to the grounding rod. Although many inverters come with integrated grounding and arc fault protection proper care to ensure complete grounding is necessary to ensure that your inverter will not be overcharged from a power outage and other outside forces.

When grounding an electrical panel the following applies grounding a main panel. Bonding and grounding pv systems ensures public safety as well as the safety of pv installers and field electricians said andy zwit codes and standards manager at ilsco. Minimal grounding is provided by a copper plated ground rod usually 8 ft. To find out more about grounding looking up the authority to full grounding techniques for your electrical system and specific environment the nec.

Drive a grounding rod at least 8 feet deep into the earth near the system. There are three main reasons for grounding in an off grid power system. Here s how we ground our solar water pump systems.
