About this topic, so a detailed source I could find did not think 🙂 or even an intermediate forum request had been my best I’ve done much good I did not have but detyl a source I find that I will share told the microcontroller, power electronics be helpful to be influenced, to give an example

LOW POWER GRID CONNECTED PV INVERTER CIRCUIT
Anthony Kahl, Geoffrey Walker Solar Energy, in particular photovoltaic (PV) power generation, will become an important alternative to traditional power generation in the years to come. This technology utilises the sun’s power directly, hence eliminating emissions and allowing the potential for very high efficiencies.
Objective of this thesis is to investigate one way of converting DC PV power to AC power suitable for injection onto the domestic power grid. There are two schools of thought when it comes to handling PV power, one involves the use of mid to high power inverters fed by series strings of PV panels. This method is fine for relatively large installations or commercial “solar farms” but lacks the flexibility required for small residential installations. The second, and the focus of this thesis, is the use of small low power inverters, one for each individual PV panel. The inverters can be incorporated into the panel itself thus resulting in a fully self contained 240VAC power generating unit. This method allows greatest flexibility whilst maintaining efficiencies comparable to larger systems.
Basic Operation of the inverter in accomplished in two stages. They involve the conversion of the 12 – 24DC V PV output to 350DC V followed by inversion to 240VAC. The unit also electrically isolates the panel from the grid via a high frequency power transformer and optically isolated feedback techniques.
