Contact UsThe above explained ideas for upgrading a low power inverer circuit to a higher power version can be implemented to any desired level, simply by adding several MOSFETs in parallel. Adding MOSFETs in parallel is actually easier than adding BJT in parallel.
Therefore, a boost converter should be inserted between the PV array and the PV inverter (PVI) to boost the voltage of the PV array under SC, but it sustains the full power of the PVI under normal conditions (NCs). To address the problem, an improved transformerless PVI with a minimum power processing unit (MPPU) is proposed.
Abstract: With the penetrations of renewable energies and electrified transportation, there is an increasing demand for power converters with wide voltage gain range operation capabilities due to the nature of the renewable energy sources, energy storage elements, and loads.
If your existing inverter is already working near to its full capacity, for example 3kW-4kW of panels with a 3kW inverter, you have two choices: upgrade to a 5kW inverter and add an additional 2kW-3kW of panels, or your new and existing solar systems will operate side by side.
For the record, a power inverter converts ~ 12V dc--> ~120 AC (normally non-sinusoidal). to increase the power output, the amount of output current the device can source is increased, whereas its output voltage remains the same.
You'll find a plenty of small and medium sized inverters in the market ranging from 100 to 500 watts, the same may be seen posted in this blog. Upgrading or converting such small or medium power inverters into massive high power inverter in the order of kvas may look quite a daunting and complex, but actually it's not.
