Can SMA inverters be used with high-current modules?
SMA inverters can easily be used with high-current modules. The absolute limit is the maximum connectable short-circuit current (I SC PV) of the inverter. The maximum input current (I DC max) of the inverter is not an absolute limit in the selection of the PV module. All SMA inverters can exceed I DC max without any problems.
How much power can a commercial inverter provide?
Large commercial inverters are in the 60 kW to 100 kW range. Inverters can be combined to provide up to or above 1 MW (1,000 kW) of three-phase power. Review Questions What determines the required input power to an inverter so that it achieves a specified output power?
What are inverter specifications?
Specifications provide the values of operating parameters for a given inverter. Common specifications are discussed below. Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage.
Can SMA inverters exceed I DC Max?
All SMA inverters can exceed I DC max without any problems. The Sunny Design planning takes all the relevant factors into account and indicates the impact on yield. SMA inverters have a connectable PV power of at least 150% of the nominal AC power. That keeps something in reserve for system planning.
What happens if a PV inverter exceeds MPP current?
Should the MPP current of the PV array exceed the maximum input current (I DC max.) of the inverter in a particular system design, there will not be any potential for damage to the inverter. Exceeding the MPP current therefore also has no impact on the inverter’s statutory warranty.
What happens if an inverter reaches a maximum power point?
Due to the common Maximum Power Point (MPP) characteristics of the inverter input, the inverter will not be able to find the optimal power point if the current is outside of the specified range. In that case, losses in energy yield can occur.
