Frequently Asked Questions

What is the DC switch on a solar inverter?
A DC switch on a solar inverter is a safety disconnect device that isolates the DC input from photovoltaic panels, allowing safe maintenance and emergency shutdown of the inverter system.
What are the PV protection devices?
PV protection devices include DC fuses, circuit breakers, surge protectors, and disconnect switches that protect photovoltaic systems from overcurrent, overvoltage, and fault conditions.
How does a DC switch work?
A DC switch interrupts direct current flow by creating an air gap between contacts and extinguishing the DC arc that forms when the circuit is broken, ensuring safe isolation of electrical circuits.
What is the purpose of the DC isolator switch?
The DC isolator switch provides safe electrical isolation for maintenance work, emergency shutdown, and load breaking under operating conditions in DC power systems and installations.
What voltage ratings are available for DC switching devices?
DC switching devices are available in various voltage ratings from 600V to 1650 VDC, with most PV and ESS applications requiring ratings between 1000-1500 VDC to handle modern system voltages.
How do I select the right current rating for my application?
Select a current rating 125% of the maximum expected current in your system, considering factors like temperature derating, future expansion, and safety margins for reliable operation.
What certifications are required for PV and ESS applications?
Key certifications include UL 98B for DC switches, IEC 60947-3 for international applications, and UL 248-13 for ESS fuses, ensuring safe operation in photovoltaic and energy storage systems.
