When grounding an electrical panel the following applies grounding a main panel.
Grounding kc 120 solar panel.
Here s how we ground our solar water pump systems.
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.
Grounding a sub panel.
Drive a grounding rod at least 8 feet deep into the earth near the system.
Sub panels are grounded through the cable that provides the sub feed circuit power.
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.
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.
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.
There are three main reasons for grounding in an off grid power system.
First ground mounted solar panel systems are very easy to place because they can be located on open land.
Chassis or mechanical and electrical.
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.
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.
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.
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.
The ground bar is bonded internally when an external bond to earth is installed as described at the link for electrical grounding below.
Ground mount solar panel systems offer benefits for all homeowners.
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.
Long driven into the earth.
When installing a solar photo voltaic system pv it is extremely important all the equipment is grounded correctly.
Leave around 6 above ground to properly attach your copper wire to the grounding rod.
Even if you seldom have electrical storms all it takes is one lightning strike or a single lose wire and all the.
This is a minimum procedure in an area where the ground is moist electrically conductive.
There are two types of ground.
To find out more about grounding looking up the authority to full grounding techniques for your electrical system and specific environment the nec.
For outdoor grounding you need to use thick bare copper wire that can handle large electrical currents like lightening.
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.
