13 Facts About Solar inverter

Solar inverter or PV inverter, is a type of power inverter which converts the variable direct current output of a photovoltaic solar panel into a utility frequency alternating current that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

Solar inverter cells have a complex relationship between solar irradiation, temperature and total resistance that produces a non-linear output efficiency known as the I-V curve.

MicroSolar inverter designed specifically for three-phase supply can eliminate much of the required storage by simply selecting which wire is closest to its own operating voltage at any given instant.

Such a device would be less expensive and less complex, although at the cost of requiring each Solar inverter to connect to all three lines, which possibly leads to more wiring.

Primary disadvantage of the three-phase Solar inverter concept is that the only sites with three-phase power than can take advantage of these systems.

However, the main advantages of the microSolar inverter concept involve issues of shading and panel orientation, and in the case of large systems, these are easily addressed by simply moving the panels around, the benefits of the three-phase micro are very limited compared to the residential case with limited space to work in.

An intelligent hybrid inverter or smart grid inverter is a solar power inverter which connects to battery storage.

Micro-Solar inverter advantages include single panel power optimization, independent operation of each panel, plug-and play installation, improved installation and fire safety, minimized costs with system design and stock minimization.

Solar inverter panels produce direct current at a voltage that depends on module design and lighting conditions.

Main problem with the string Solar inverter approach is the string of panels acts as if it were a single larger panel with a max current rating equivalent to the poorest performer in the string.

MicroSolar inverter attached to a single panel allows it to isolate and tune the output of that panel.

Monitoring and maintenance is easier as many microSolar inverter producers provide apps or websites to monitor the power output of their units.

In 1991 the US company Ascension Technology started work on what was essentially a shrunken version of a traditional Solar inverter, intended to be mounted on a panel to form an AC panel.
