Share The Minute Mate DC isolator comes fitted with four integral Type 4 connectors – so the unit can simply be plugged in to the final solar PV panel in the array, and the inverter.

A spike in fires caused by DC isolators has alarmed the NT's workplace safety watchdog, as figures show most other jurisdictions are also recording fires from the devices.

The report warns that DC isolators – intended as a safety mechanism to disable dangerous high-voltage DC between the solar array and inverter – “can easily degrade and malfunction” and ...

Single-axis tracker systems, frequently used in large solar installations, can cause increased mechanical stress on unsecured wiring and connectors within the DC system due to their regular daily ...

Conclusion It is essential to know the significant difference between an AC and DC isolator switch. Is a DC or AC circuit being created? Is an inductive or resistive switch to be used?

The PV series are not just suitable for solar arrays. The wide input range and isolation levels make them suitable for use a wide variety of industrial applications as front end power supply ...

You must provide ground fault protection for DC photovoltaic (PV) arrays. But you don’t have to, if they are ground- or pole-mounted PV arrays with not more than two source circuits isolated from ...

While most utility-scale PV developers are grappling with the choice of string or central inverters, is “Yet Another PV Architecture: Medium Voltage DC Plant (MVDC)” ready for consideration?

Case study examines a common PV inverter failure that can drive uncommon issues in the field — namely, damage to the AC protection equipment from DC fault currents for short periods during transformer ...
