Solar Inverters grid connected from 1.5kW to 1MW

A solar inverter or PV inverter converts the variable direct current (DC) output of a photovoltaic (PV) solar panel or solar array into a utility frequency alternating current (AC) that can be fed into the electrical grid or used by a local, off-grid electrical network/ island solution. A solar inverteris an essential part in a photovoltaic system. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Micro inverters

Solar micro inverter , converts (DC) electricity from a single solar panel to AC,improving the system’s efficiency up to 25%

Solar micro-inverter or micro inverter, converts direct current (DC) electricity from a single solar panel to alternating current (AC). Micro-inverters have several advantages over conventional central inverters. The main advantage is that, even small amounts of shading, debris or snow lines in any one solar panel, or a panel failure, does not disproportionately reduce the output of an entire array. Each micro-inverter obtains optimum power by performing maximum power point tracking for its connected panel. Each micro inverter is individually connected to one PV module in the solar panel array. This unique configuration achieves Maximum Power Point Tracking(MPPT) at the PV module level, thus eliminating single-point failure, minimizing the effect of shading, soiling, orientation or PV module ageing, and improving the system’s efficiency up to 25%.

 

The conversion is performed by a solar inverter; also known as a grid tied inverter

Advantages of a micro inverter
Panel level MPPT (Maximum Power Point Tracking)
· Increase system availability – a single malfunctioning panel will not have such an impact on the entire array
· Panel level monitoring
· Lower DC voltage, increasing safety. No need for ~ 600 V DC cabling requiring conduits
· Allows for increased design flexibility, modules can be oriented in different directions
· Increased yield from sites that suffer from overshadowing, as one shadowed module doesn’t drag down a whole string
· No need to calculate string lengths – simpler to design systems
· Ability to use different makes/models of modules in one system, particularly when repairing or updating older systems
