A CC/VC‐based power tracking method for photovoltaic inverter

The PV inverters with the proposed method successfully handle this problem as the PV2 changes its output power to compensate the shortage power and the PV1 quickly tracks the desired operating point within 0.04 s. After that, the PV inverter stably operates until the load increases at 4 s and the power shortage is triggered again.

How Does Sizing A Solar Inverter Work?

The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1.

PV Interconnection: Load-Side vs. Line-Side

This is a common setup in our area, which is prone to frequent electrical shutoffs. If the inverter connection is on the load side, it will kick on when the generator kicks on, but without the capacity to take the energy produced, causing a voltage surge. A connection on the supply side will keep the inverter off when the utility supply is off.
