6 FAQs about [Photovoltaic circuit board selection requirements]
Why is circuit breaker selection important in solar PV systems?
Background In solar PV systems, circuit breaker selection is something that is easily overlooked and time should be taken to select the correct solution. If the circuit breaker is not appropriate, it will cause frequent tripping of equipment, overheating damage and even system fire.
How to choose a circuit breaker in a PV system?
For the selection of circuit breakers in PV systems, temperature is the most important consideration. According to the IEC 60947-2 standard, all circuit breakers have a datasheet detailing the derating/increasing current value of the ambient temperature.
Are there any UK standards relating to a PV installation?
While many UK standards apply in general terms, at the time of writing there is still relatively little which specifically relates to a PV installation. However, there are two documents which specifically relate to the installation of these systems that are of particular relevance:
Are all PV products covered by IEC61730 'photovoltaic (PV) module safety qualification?
In future it is expected that all PV products will increasingly be covered by International standard IEC61730: 2004 ‘Photovoltaic (PV) module safety qualification’.
What are the requirements for a PV installation?
Virtually all domestic PV installations will fall under the scope of Part P. Part P requires the relevant Building Control department to be notified and approve the work. There are two routes to comply with the requirements of Part P: Notify the relevant Building Control department before starting the work.
What are the current ratings assigned to PV circuit breakers?
The current ratings assigned to PV circuit breakers are defined by the performance requirements of UL 489B in order to protect PV modules during overcurrent situations. MCCBs and MCS’ are listed for a continuous load application. The assigned service rating should be reduced at increased ambient temperatures above 50°C.
