Great CC... no TC
on October 15, 2007
CC-10000 is a fantastic charge controller, simple, reliable and inexpensive. Unlike most of its competitors in the same price range, it's a two-stage controller. It will float at 13.7V but will boost up to 14.5V for up to two hours once battery has dipped below 12.5V. (Morningstar's SunSaver just maintains constant voltage (14.1V for sealed/14.4V for flooded batteries) -- way too high for float but not quite enough for absorption). It goes without saying that it's a PWM design, for efficiency and long battery life.
My only complaint about it: it is not temperature-compensated (I've just confirmed this with the manufacturer). This should be OK if it is used indoors only (as the manual unconspicuously recommends), or in the mild climate. If, on the other hand, it is used e.g. in sub-freezing temperatures, it will under-charge the battery by half a volt or more. So if you absolutely must have temperature compensation, check out CC-25000 (twice the price) or consider another brand.
