The grid tie inverter is generally adjusted by PWM. There is a term called duty ratio, which is equal to the component series voltage/ DC bus voltage. The duty ratio has a close relationship with the efficiency. A higher duty ratio tends to generate smaller voltage difference and higher efficiency. [pdf]

DC-coupling refers to a co-located battery and solar farm being connected behind a shared inverter - where power is in direct current (DC). Both assets operate in DC - and require an inverter to convert electricity to/from the alternating current (AC) in which the electricity grid operates. [pdf]
[FAQS about DC coupling of the inverter]
The inverters overcome the major drawbacks of the conventional CSIs-high device voltage stress, low operating-frequency range, large commutation capacitance, etc.-by using a simultaneous recovery and commutation concept. They use only one commutation capacitor and can be built at very low cost. [pdf]
The main reason for oversizing an inverter is to drive it to its full capacity more often. Oversizing the inverter is not a requirement. An experienced PV designer might choose to. .
SolarEdge allows DC/AC oversizing depending on the inverter model. [pdf]
[FAQS about The inverter outputs more than 200 volts of DC]
An inverter overload occurs when the power demand from connected appliances exceeds the inverter’s maximum capacity. The gap in supply and demand causes the inverter to draw excessive current. This results in overheating and potential damage. [pdf]
[FAQS about DC inverter overpower]
As solar PV panels produce DC electricity, this electricity is fed into the combiner box via cables to its input ports; its internal circuitry then aggregates and redistributes it, sending it to inverters or additional apparatus. [pdf]
