1 Array voltage of 50V can only be applied with a 24V battery,
otherwise the unit will be damaged.
2 If the battery is lower than 17V, the charger will recognize it
as a 12V battery.

RELATED SYSTEM EQUIPMENT

TM
The Sunsei CC25000 is an integral part of a solar electric
power system that includes a solar panel, a battery and a
load.
SOLAR PANELS ("photovoltaic (PV) array", "solar modules"):
The Sunsei TM CC25000 is compatible with all makes and
models of photovoltaic solar panels.
The entire solar array's open circuit voltage (Voc) cannot
exceed 30V with a 12V battery or 50V with a 24V battery (the
sum of the Voc of all solar panels in series). Also, the solar
array's peak operating current (Ip) cannot exceed 25A. (This
is the sum of the peak operating currents (Ip) of all the solar
panels in parallel).
Install all panels with the correct series-parallel confi guration
to ensure proper system voltage and current.
The Sunsei TM CC25000 circuitry uses a MOSFET transistor to
eliminate leakage of the battery power into the solar panels at
night. No additional protection is needed.
OTHER CHARGING SOURCES: Systems with an additional
source of charging (alternator, battery charger, etc.) can
operate with a solar array and a Sunsei
charging sources need to connect directly to the battery on
independent lines and have their own form of over-charge
protection.
Sunsei TM CC25000 FOR NON-SOLAR APPLICATIONS:
These units will only operate with solar electric panels. Do not
use to regulate other power sources, such as a hydro or wind
generators/alternators or AC battery chargers. These charging
sources can damage the controller and/or the generating
equipment.
BATTERIES: The Sunsei
charging of standard lead-acid batteries that are normally
used in recreational vehicles, boats and remote stand alone
systems. These include wet cell batteries (with fi ller caps),
sealed, maintenance-free and gel-cell batteries. Automobile
batteries can also be charged, but these batteries are rarely
used as the primary battery in a solar system. Install all batteries
with the correct series-parallel confi guration to ensure proper
system voltage and current.
SYSTEMS WITH TWO BATTERY BANKS: When solar
charging two separate battery banks, a switch can be installed
to allow manual selection of one battery or the other.
BATTERY ISOLATORS: In installations that use a diode
battery isolator with two batteries, the Sunsei
needs to connect directly to one of the batteries or an output
from the isolator.
