Allan,
Are you running 100+ volts DC through a Square D breaker? They are not
rated for anything above 48VDC. Midnite Solar makes a manual transfer
switch that can be fitted with 150 VDC breakers. That may be a better
choice.

Allan,
Here the electrical inspector won't let us install the CU-200 or other
SQFlex controls because they are not UL listed. The pump is not
listed either, but he doesn't object to that. So I've installed the
SQFlex pumps using a pair of SQ D QO breakers with interlock kit so
they can be run on a generator or solar system. To turn them off, a
2-gallon pressure tank with pressure switch (adjusted to operate at 10
psi) works great if the PV array is near the pumping system.
