Inverters are a component needed for PV solar installations requiring alternating current or AC electrical power. Solar panels generate direct current or DC power. The inverter changes DC power to AC power for further more use at homes installations whether on-grid or off-grid.inverter is an essential component in any solar power system, and have to intelligent and responsible yield monitoring management system

What should we know about solar inverters

There are 4 basic types of solar inverter: String, String + Optimizer, Micro-inverter, and Hybrid.

string (grid tiled) inverter is the most economical approach. Works just fine in direct Sun when shade is not an issue. Multiple strings, or groups of panels, are wired together, and than connected to the inverter. Each string operates independently. The string inverter working time is 15 to 20 years. String are ideal for ground-mounted systems or buildings where rooftop shutdown is not required.

String inverter with Optimizer has a small device added to the back of each panel to optimize performance. Each panel operates independently, it can be monitored, and includes rooftop shutdown capability. Optimizer help minimize shade losses and improve overall performance.

Micro-inverters has device to back of each panel to optimize performance and convert from DC to AC power. Each panel operates independently, it can be monitored and includes rooftop shutdown capability. Micro-inverters help minimize shade losses and improve overall performance. The smaller electronics has a longer life, for example Enphase has a 25 year warranty.

Hybrid inverter can work both on-grid, or off-grid with batteries. The solar panels and storage batteries are in one unit. The hybrid inverter also has an internal power transfer switch to deliver power during an outage. Some hybrid inverters even lets connections to a fuel generator or another power source to charge batteries.

Inventer main characteristic are :

Maximal DC input power from 350W and more

Maximal DC input voltage from 50 to 60 V

Maximum AC output power from 245 W and more

Maximum continuous AC output power from 245 W and more

Nominal AC output power from 240 W and more

Maximum continuous AC output current from 1 to 2 A

Maximum units per 20 A branch circuit
