Most of the modern solar power systems have a number of safety features integrated. While solar inverters alone have safety features constructed into them to protect your solar power equipment from too much voltage, adding cut off switches and breakers will add the minimum required safety measure to protect your inverter.
FAQs ABOUT SOLAR PROTECTION
Do I really need additional solar protection?
It isn’t standard to have fuses or breakers back when solar power was a young technology. As it is, there’s already a small chance of fire even if back feed happens. The glass, aluminum, silicon and other components should be durable enough to withstand combustion – that is, if you get your equipment from a reliable provider.
The difference between using additional safety switches and breakers is pretty cheap and the amount could easily be justified by the sound sleep and assurance that they provide.
Where do I put these protections?
Common protection measures include adding fuses or breakers between panels and the controller. Additional solar protection on the array as a whole is not necessary electrically but may be needed to meet local inspection or a breaker can be used as a convenient array disconnect.
It is also advisable to add protection between the battery and the charge controller. If possible, it’s best to add protection from the battery to every load including the inverter as well.
How do I know what size of solar protections I need?
We normally recommend reading up on the NEC or having your system professionally designed for this matter.
Here are just some items you may want to consider in sizing the right switches and breakers:
- Solar Panel
- Battery Fuse/Breaker to Inverter
- Charge controller to Battery Fuse/Breaker
- Parallel/Combiner Box
