Default Re: Solar Panels and CME

I was referring to photo voltaic cells not heat exchangers. If you have solar hot water, then unless there is an electric pump I doubt CME or EMP would be a concern.

Low voltage is usually considerered to be anything where the voltage is less than 60 volts.

Normally this means 48v or less since the main voltages for solar power systems are 12/24/48v - this is down to common arrangements for battery arrays being in multiples of 12v.

Higher voltages are found in grid tied systems, but they are no good in a CMP/EMP because without the grid, they are useless.
