FAQs 6

What is a power limit in a solar inverter?

The setting is percent-based. It is the desired active power limit divided by the nominal power of the inverter, as shown in the equation below. For example, this means if a user wants the inverter to only generate a maximum of 3.6kVa (for EEG2012, 70% of the kWp of the PV array) and the inverter has a nominal rating of 5kVA.

How do you calculate the power limit of a PV inverter?

It is the desired active power limit divided by the nominal power of the inverter, as shown in the equation below. For example, this means if a user wants the inverter to only generate a maximum of 3.6kVa (for EEG2012, 70% of the kWp of the PV array) and the inverter has a nominal rating of 5kVA. The user must calculate the percent as shown below.

What is a control state in an inverter?

Each control state is a combination of the following three fields: AC output power limit – limits the inverter’s output power to a certain percentage of its rated power with the range of 0 to 100 (% of nominal active power). CosPhi – sets the ratio of active to reactive power.

How does a PV inverter work?

One method used for this purpose is limiting the export power: The inverter dynamically adjusts the PV power production in order to ensure that export power to the grid does not exceed a preconfigured limit. To enable this functionality, an energy meter that measures export or consumption must be installed at the site.

How to reduce the load of an inverter?

So, you need only to set the reference current of the inverter to a smaller value. The other solution could be implemented in the design phase where one divide the array into two equal parallel strings. In this way one can connect only one of the two strings to the input of the inverter when the load is reduced.

What is the difference between power limit and current Lim?

Power Limit – limits the inverter maximum output power. The power limit can be set to any value between 0-100 [% of nominal active power]. Current Lim – Current Limit: limits the inverter’s maximum output current (available from inverter CPU version 2.549).
