Pairing the CH200 with the SP90-L allows the CH200 to operate at the maximum useable solar
current of 4.3 A for longer periods of time than it would with a smaller panel. As the SP90-L
output current increases above 4.3 A, the CH200 will continue to function at the maximum
useable solar current of 4.3. It will remain at this level until the SP90-L output once again drops
below 4.3 A. To take advantage of current levels above 4.3 A, the CH201 with a maximum current
of 10 A must be used.
NOTE:
A second solar panel can be connected to the CH201 when additional power is required. One
CH201 can handle two SP50-L or two SP90-L solar panels.
(p. 3) shows how two
solar panels are wired in parallel, leaving the second DC input terminal free for an alternate
source of DC voltage.
