6 FAQs about [50kW inverter high frequency protection setting]
Can a PV inverter be set to stand-alone mode?
The PV inverter can be set to stand-alone mode and reduce its feed-in power if this is required by the battery state of charge or the energy demand of the connected loads. To do this, use the integrated frequency-shift power control (FSPC). Selecting the PV Inverter You can use the following PV inverters in off-grid systems.
How does a PV inverter monitor the frequency change?
This frequency change is monitored by the PV inverter. As soon as the power frequency increases beyond the value specified in FAC Start Delta, the PV inverter limits its output power accordingly. fAC refers to the base frequency of the stand-alone grid (here 50 Hz).
How much AC power should a sunny island inverter have?
In off-grid systems, the nominal AC power of the PV system must not be more than double the nominal AC power of the Sunny Island inverters. The battery capacity per installed kWp of the PV array must be at least 100 Ah. Example: In a PV array with 5 kWp, the battery capacity must be at least 500 Ah.
Can I use PV inverters in off-grid systems?
You can use the following PV inverters in off-grid systems. You can order all the listed PV inverters with preset off-grid parameters from SMA Solar Technology AG. The PV inverters must be equipped with at least the firmware version given in the table, or a higher version.
What is the battery capacity of a PV inverter?
The battery capacity per installed kWp of the PV array must be at least 100 Ah. Example: In a PV array with 5 kWp, the battery capacity must be at least 500 Ah. To change grid-relevant parameters in the PV inverter after the first ten operating hours, you will need a special access code, the SMA Grid Guard code.
