Technical FAQs 4

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 to control the maximum power output of a solar inverter?

Set this parameter to Percentage fixd-value limitation (open loop) to control the maximum power output of the solar inverter in different periods of a day. If the solar inverter needs to run with specified maximum power in certain periods of a day, add setting records based on site requirements.

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.

How to set a solar inverter to run at full load?

Log in as Special User, and choose Monitoring > SUN2000 > Running Param.Power Adjustment. On the displayed page, ensure that Remote power schedule is set to Enable. Set the parameters for active power control and click Submit. If this parameter is set to No limit, the solar inverter runs at full load.
