Technical FAQs 4

How does a power inverter control reactive power generation?

A power inverter controls reactive power generation by adjusting the phase relationship between the output voltage and current. When the voltage leads the current, capacitive reactive power is generated, whereas if the current leads the voltage, inductive reactive power is produced.

Do all inverters have reverse polarity protection?

Depends on if it has "reverse polarity protection" or not, not all inverters do. Most grid-tie inverters include DC reverse polarity protection, and it usually consists of a reverse-connected shunt diode.

What is reverse active power protection?

Reverse active power protection calculates the active power with the RMS values of the voltages and currents. A time delay is associated with the protection. The positive sign of active power is defined by the power sign setting. The same sign is used for active power measurement.

How does a reverse current meter work?

When reverse current is detected, the meter communicates the backflow data to the inverter via RS485 communication. The inverter responds within seconds, reducing its output power to ensure the current flow into the grid is nearly zero. Anti-Backflow Solutions Different configurations are available to meet various scenarios:
