The C35 (35 Amp controller) has long been the main stay of Xantrex’s
charge controllers because of it versatility and reliability. The C35 is
a 100% solid state, microprocessor-driven controller which is UL and
cUL listed. The C35 controller may be configured for solar panel battery
charging, or DC load control (e.g. low voltage disconnect) or DC
diversion operation (e.g. wind turbines and hydro generators). Whatever
the charging source, the C35 Xantrex Charge Controller is sure to meet
your DC controller needs.
Note that the C35 does NOT have the black aluminum heatsink shown in the product photo. Only the C40 and C60 require the black aluminum heatsink to handle the higher current ratings.
