I want to use a solar charge controller STECA PR2020 to supply the RUT240. The Output voltage of the solar charge controller can be up to 29.4V which is quite near the given RUT240 's maximum of 30V.  How high can the voltage peaks be, without destroying the RUT240?

Hello,

Recommendations are within 9-30V for RUT240. Something higher or just peaks of voltage won't damage it, but it's better to avoid that slim chance of burning it if peaks get too high.
