The inverter has disconnected from the utility grid. Check whether the grid voltage at the connection point of the inverter is permanently in the permissible range.
If the grid voltage is outside the permissible range due to local grid conditions, contact the grid operator. The grid operator must agree with an adjustment of the voltage at the feed-in point or with a change of the monitored operating limits. If the grid voltage is permanently within the permissible range and this message is still displayed, contact Service. The ten-minute average value of the grid voltage is no longer within the permissible range.
The grid voltage or grid impedance at the connection point is too high. The inverter disconnects from the utility grid to maintain power quality. During the feed-in operation, check whether the grid voltage at the connection point of the inverter is permanently in the permissible range. A stand-alone grid or a very large change in the power frequency was detected. The power frequency is not within the permissible range. If possible, check the power frequency and observe how often fluctuations occur.
If fluctuations occur frequently and this message is displayed often, contact the grid operator and request approval to change the operating parameters of the inverter. If the grid operator gives his approval, discuss any changes to the operating parameters with the Service. The inverter has detected an excessively high proportion of direct current in the grid current. If this message is displayed frequently, contact the grid operator and check whether the monitoring threshold on the inverter can be raised.
The AC cable is not correctly connected or the country data set is not correctly configured. Check whether the DC voltage is below the maximum input voltage of the inverter. If the DC voltage is below the maximum input voltage of the inverter, reconnect the DC connectors to the inverter.Forums New posts Search forums. What's new New posts. Log in Register.

SMA can't tell me what wires I need to run to my inverters. Is it 3 hots no neutral help GoldDigger Moderator Staff member. GoldDigger said:. Often there is a configuration jumper to select one mode or the other, which primarily changes what the unit is looking for when qualifying the grid.
Is it 3 hots no neutral help. The SMA grid guard settings are the inverter settings that control how the inverter reacts to changes on the grid. Typically the inverter comes preprogramed with the settings appropriate for where it is being installed but sometimes there are local variations that require these setting to be changed.
The settings are accessed with a Grid Guard Code you get from SMA, because they don't want just anyone mucking around in the settings. I have no idea why SMA would give this to you in response to your situation. It does not jive.

They have been installed by Solargain from until present. SMA inverters initially came with a 5-year warranty with the option to extend it to 10 years. Solargain can assist you with any SMA warranty issues. We will need the fault code and serial number to lodge an insurance claim.
Some faults will require testing prior to lodging the claim, though. We recommend adding a health check to the attendance to ensure that there are no underlying issues with your installation.
SMA has the fastest industry response to warranty claims with a response time of about 5 working days. If your SMA inverter is out of warrantyyou will need to purchase a new inverter in the closest possible size. Some faults, like varistor failure, can indicate a surge has occurred and can therefore be covered by insurance, although, sometimes, the cost of repair is less than the excess, depending on your policy.

Please note that the personal SMA Grid Guard code for changing the grid-relevant parameters must be available after completion of the first ten feed-in hours see "Application for the SMA Grid Guard code" available at www.
I'm in the US and purchased the inverter from a large US seller, so I don't anticipate needing to change the grid parameter, unless they are not already set to US. I have the unit mounted and powered up, but the web interface is limited in functionality until the inverter comes on-line, which will be Tuesday when I install the panels not here yet. Just curious if I need to submit an application for this code. There's a 59 Euro fee as well.
Tags: None. After watching the SMA deployment video, I think what the manual is saying is that you have 10 hours to set the unit to the correct grid config, and after 10 hours, the settings are locked and you need to code to make changes in the future.

The existence of this scenario was discovered and proven to exist by Willem Westerhof during his internship at ITsec in late Following the responsible disclosure period, details are now made available to the public. As an addition to reading this website, you could also check out the presentation at SHA The Horus scenario, is a scenario describing a large scale cyber attack targeting the vital electrical infrastructure. This scenario was both theoretically and practically proven to exist during the thesis of Willem Westerhof.
Horus is an ancient Egyptian god, refered to in many different ways, which is in most cases related to the heavens or the sun. In mythology, one of his eyes stands for the sun, the other one of his eyes stands for the moon. In essence, this means that a scenario was created and proven where a malicious hacker targets the electrical grid by focusing on PV-installations and succeeds in causing large scale Nation-wide or even continental power outages.
The power grid needs to maintain a constant balance, between supply of power, and demand of power. If supply exceeds demand, or demand exceeds supply, outages can occur. In order to maintain stability all sorts of countermeasures exist to prevent outages due to peaks or dips in demand or supply.

Under normal circumstances, these countermeasures ensure grid stability. There is however a limit to these countermeasures.
A maximum peak or dip value in a specific period of time. If an attacker is capable to go beyond this maximum peak or dip value, outages will occur. The thing with power grids, at least in Europe, is that they are very intertwined. Nations are constantly exporting and importing power to each other, and power grid regulators have made agreements to help each other during crisis times.
Because of this intertwinedness an attack or failure of any part of the power grid, automatically has effects in other intertwined power grids as well. PV installations influence the balance of the power grid in two ways. They supply power directly to local appliances lessening the demand and any excess power is supplied to the grid increasing the supply.
An attacker capable of controlling the flow of power from these devices can therefore have a direct effect on the balance of the Power grid. The available countermeasures for grid stability will easily protect us from such an attack. Hacking these devices becomes a problem when done at a large scale. In Europe there is over 90 GW of PV power installed, an attacker capable of controlling the flow of power from a large number of these devices could therefore cause peaks or dips of several GigaWatts causing massive balancing issues which may lead to large scale power outages.
In order to proof that this scenario is possible, two methods were used. A statistical method, and a comparison to the solar eclipse. Using a mathematical model it is possible to estimate the amount of PV energy in a power grid at a given time. Based on this model as well as official sources it was determined that an attack like this is statistically possible.
Almost instantly causing a very large nation-wide, up to continental due to the intertwined power grids power outage. Sadly, it is impossible to determine exact numbers on the threshold values though hearsay shows a range of GW. It is simply too costly for power regulators to have that amount of power balancing on standby at all times. It may even be impossible, to have that kind of reserves trigger instantly as power plants take quite some time to increase and decrease their overall power output.
