FAQS 4
What are the protection circuits of the inverter?
Protection circuits of the inverter: (a) overcurrent protection circuit, (b) overvoltage protection circuit, and (c) under voltage protection circuit. A PV power-generation system with a phase-shift pulse-width modulation (PWM) technique for high step-up voltage applications is proposed. The proposed power-generation system consists of two stages.
What is the protection function of solarriver-D series inverter?
Introduction of SolarRiver-D series inverter 3.4 Protection function 【Grounding fault】 SolarRiver-D series inverter is designed as floating connection with PV ( positive and negative terminals are not connected to ground ). When there is grounding fault, the inverter will be shut down and display grounding fault.
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.
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.
