SOLAR BATTERY
BACKUP BOX
BENEFITS INCLUDE
• This special solar battery backup unit is
used to store solar energy for day and
night use and is originally designed for
fountain pumps, but its application could
be universally extended to air pumps and
lights.
• The input power should be from the solar
module or DC power supply with an
output voltage of 18v.
• There are four output ports each of
which has a different output voltage. The
electronic connector of the appliances
to their output 1 (6V), 2 (12V) and 3
(18V) should be compatible with the
output port. The interface of output 4
(12V) is of universal terminal which could
be compatible with any applicable dc
equipment.
• The battery station has built in protection
for overcharging and over discharging.
• There are seven LED indicators to show
the status of system charging, timer,
output 1, output 2, output 3 and output 4.
The system indicator is bicolour.
• Green shows the battery is in normal
operating status. Red shows the battery
is in low voltage status, which requires
the battery to be recharged and Red-
Green flashing shows the battery is
preparing its readiness to output.
• Timing function is provided only for
output 3 (18V) to reduce the energy
consumption. The pump connected to
output 3 will work 10 minutes every hour
periodically by the time, as energy saving
mode, it is especially useful in winter or
on cloudy days.
