Welcome to Nordic Inverters, a leading provider of advanced solar inverters and energy storage solutions. Our mission is to empower businesses and homeowners to harness the power of renewable energy, paving the way for a sustainable and greener future.
[pdf] Use an EI or toroidal transformer with a 12V center-tap primary and a 220V secondary. Ensure the core supports the target power output–typically 300–1000W–without saturation. If you use ferrite cores, adjust the switching frequency between 20 kHz and 50 kHz to reduce audible noise.
[pdf] Special inverters can be connected together to produce 220-volts. This process is called stacking. This process cannot be used for any type of power inverter. The inverter has to be specifically designed to allow stacking.
