Customer Service690.2 – Definition of Grounded, Functionally Change at a Glance: The previous definition for "Functional Grounded PV System" was revised to "Grounded, Functionally." Informational Note also revised to clarify the operational purposes for functionally grounding a system. 690.2 Definitions. [Solar Photovoltaic (PV) Systems]
Customer ServiceWhen I connect the positive and negative leads that run directly from the PV Controller to the house batteries, the PV and controller does not work. If I remove the leads that power the RV from the house batteries but leave the PV pos and neg leads attached, then the system is a stand alone PV/Controller/Battery and it works fine
Customer ServiceIsolating devices shall be provided to isolate PV modules, ac PV modules, fuses, dc-to-dc converters inverters, and charge controllers from all conductors that are not solidly grounded. While the wording changed I think it still says basically the same as the 2014 690.15.
Customer ServiceIn my off grid cabin I want to install a victron smart solar mppt controller 100/30. I noticed on the side of the controller there is a screw for grounding. Does this connect to a grounding rod hammered into the ground outside.
Customer ServicePhotovoltaic (PV) System is the combination of components, circuits, and equipment up to and including the PV system disconnect, that converts solar energy into electrical energy [100]. Inverter Generating Capacity is equal to the sum of parallel-connected inverter maximum continuous output power at 40°C in watts, kilowatts, volt-amperes, or kilovolt-amperes [100].
Customer ServiceCheck your AHJ and Utility for disconnect needs. My utility required one at the panel (even though my meter panel has a breaker inside it too). You mention rapid shutdown in your title, another check your AHJ, mine did not need it since it was not "on the house".
Customer ServiceUse Your DMM on a Dark Panel and measure resistance between ground and panel positive. 0 or less than 1 Ohm = Grounded. Open Circuit = Not Grounded. If it is grounded, as soon as you connect the panels, they are shorted out and will not work.You will need different panels. Ground is a nasty thing and can get you hurt or burnt. So far just dark.
Customer ServiceI am wiring up the solar system in my van and I need help with claryfing some things up. I have a Phocos CA08-2.2 controller and in the manual one can read: Be aware that the positive terminals of the controller are connected internally and therefore have the same electrical potential. If any grounding is required, always do this on the
Customer ServiceAs I navigated these solar panel not charging battery issues, I also discovered the importance of a properly sized system; undersized panels can''t keep up with the energy demands. By sharing my journey through these common issues and solutions, I hope to help others facing similar challenges. Continue Reading to Understand These Key Points: Check
Customer ServiceNet metering is a great way to save money. It lets consumers get credit for extra solar energy they put back into the grid. This can cut down their electricity bills, making solar energy more affordable. This also makes solar power easier to use. Cost Savings for Consumers. With a net metering setup, those with solar panels can lower their
Customer ServiceIf your charge controller is not grounded, then it may not be able to properly control the charging process and damage may be done to the batteries. Therefore, make sure to do your research and purchase a charge controller

Customer ServiceIn my off grid cabin I want to install a victron smart solar mppt controller 100/30. I noticed on the side of the controller there is a screw for grounding. Does this connect to a grounding rod
Customer ServiceThe DC side of the inverter is grounded, along with the charge controller, to a unique earth stake ( panel frames are grounded to a separate earth stake and have surge protection earthed to this ground stake). The AC side of the inverter( connected to the DB board) has a standard earth leakage grounded to the house earth.
Customer ServiceFrom what I''ve read the general consensus for 12V DC off-grid systems seems to be that you should run a ground wire from components such as the Inverter and MPPT Charge Controller to the DC negative bus bar, and
Customer ServiceSolar inverters can be grounded by using a grounding rod made of copper. That rod should be connected to a common grounding point and copper grounding wire is used for that purpose. It is better to have an electric panel connected to a single ground point. Grounding solar inverter can be done using the following steps: Step 1: First of all, proper
Customer ServiceThe DC side of the inverter is grounded, along with the charge controller, to a unique earth stake ( panel frames are grounded to a separate earth stake and have surge
Customer ServiceIf they are isolated, then you must ground a current-carrying wire, and connect it to casings (to trip OCPDs during line-to-case faults). But this is only regarding system grounding, not equipment grounding.
Customer ServiceGrounding is one of the most critical elements of any solar panel installation. Not doing so can lead to static discharge and lighting strikes that destroy the solar panel, inverter, battery and
Customer ServiceIt''s not unusual for solar charge controllers to be "positive common"/"positive ground". Of course, the controller doesn''t care what you connect to earth ground... but in a "positive common" system, the (+) legs of the battery, load, and solar panels are connected together, and the switching is done on the (-) leg. So if you want to

Customer ServiceFrom what I''ve read the general consensus for 12V DC off-grid systems seems to be that you should run a ground wire from components such as the Inverter and MPPT Charge Controller to the DC negative bus bar, and then run a ground wire from DC negative bus bar to a grounding earth point (in my case, via the grounding bus bar in my Solar Panel
Customer ServiceSolar panel systems come with their own set of equipment that must be properly installed and maintained. One of the most critical components is the solar inverter, which converts the DC power from the solar panels into
Customer ServiceThere is no way to connect to house earth cable and there are no metal parts outside of the shed. For the reference of future viewers: if you do want to ground a system like this, beware how you do it. It's not unusual for solar charge controllers to be "positive common"/"positive ground".
It's not unusual for solar charge controllers to be "positive common"/"positive ground". Of course, the controller doesn't care what you connect to earth ground... but in a "positive common" system, the (+) legs of the battery, load, and solar panels are connected together, and the switching is done on the (-) leg.
If I understand the electrical code (and I may not), bringing and running a system ground wire out with the PV wires from the inverter (or whatever panel in the house) to the ground mount is a requirement. However many of these ground mounts are 100's of feet from the house and the AC ground rod.
If you are up on a hill and are likely to draw lightning, I would recommend grounding. More importantly, you should place spikes slightly away from the panels and slightly above them so that they draw charges from the air and attract a lightning before it hits the panels.
I've also read that 12V off-grid / standalone systems (like mine) don't need to be grounded, but nonetheless, I'd like to understand / learn how to do it right. Looking for any ground wiring feedback / comments please based on my diagram below.
Bringing the system ground out from the inverter to the ground mounts and/or grounding the mount and frame to a ground rod at the mount (or both).
