FAQS about Grid tie solar inverter in Portugal

What is a grid-tie inverter?

A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid.

Which solar inverters are available for on-grid applications?

Grid tied solar inverters for on-grid applications to convert DC power into usable AC power - including string, DC-optimized and hybrid inverters. We stock single and three-phase inverters for residential and commercial applications from Fronius, GivEnergy, SMA Solar, Solis and SolarEdge Technologies.

What is the best grid tie inverter?

When it comes to power, there is simply no stronger grid tie inverter out there than the SMA Sunny Boy 5000W inverter. At 5000W, this mammoth can handle just about anything your solar panels can throw at it, and shouldn’t face any problems even during peak sunlight hours around midday.

How does a grid tie inverter work?

A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal computer that senses the current AC grid waveform, and outputs a voltage to correspond with the grid.

What types of solar inverters are available?

We stock single and three-phase inverters for residential and commercial applications from Fronius, GivEnergy, SMA Solar, Solis and So Grid tied solar inverters for on-grid applications to convert DC power into usable AC power - including string, DC-optimized and hybrid inverters.
