1700W Solar Battery Charger
Maximum Power Point Tracker
MPPT30-1 General Information:
•
Green LED On – Battery Ok.
•
Green LED Flashing – Battery Low.
•
This MPPT is designed to auto detect 12V, 24V or 48V battery systems and select a
suitable charge regime.
•
The MPPT 30-1 is shipped in a sealed battery setting which is the safest setting but if your
batteries are vented then,
BEFORE
wiring the MPPT in, follow the
CHANGING BATTERY TYPE SETTING PROCEDURE.
•
The maximum absorption voltage is 14.5V, 29V or 58V and the float voltage is 13.5V, 27V
or 54V for 12V, 24V or 48V batteries respectively.
•
The absorption phase is entered following a low battery condition or dawn and is
maintained until the battery demand falls below 1.5A.
•
Custom float and absorption voltages and thresholds are possible but minimum orders apply.
•
This MPPT has a built in multilevel over temperature protection to improve product reliability
while maximising output power availability.
•
The maximum continuous output power is 1700W in 48V systems, 850W in 24V systems
and 425W in 12V systems. The output current is limited to 30A.
The MPPT 30-1 is designed to charge sealed and vented lead acid batteries from
photovoltaic pannels. Silicon based panels such as monocrystalline, polycrystalline and
amorphous are suitable.
Important Notes:
• Use only PV Systems with open circuit voltage below 95V and a V
MP
of 18V for 12V Charging
36V for 24V Charging and 72V for 48V charging.
• This equipment must be installed by qualified personnel only and incorrect wiring can cause
fire, injury or death – GSL will accept no responsibility for MPPT misconnection or misuse.
• Use only sealed or vented 12V, 24V or 48V lead acid batteries and confirm the MPPT settings,
charge voltages and currents are correct for your battery system – if in any doubt seek
qualified advice!
• Use wires suitable for at least 40A, but if wire runs are over 3m then larger wires are
recommended to limit voltage drop and losses.
• Install the unit in a dry place out of direct sunlight and away from flammable liquids or gases.
• Battery fuse ( BF ) is always required and must be located as close to the battery as possible,
its sizing depends on the wire size and load ratings. Typically a 40A 60VDC fuse would do.
• Before connecting the battery always check the battery and PV panel polarity.
•
Optional Diode
A suitably heatsinked 40A 60V schottky diode ( its anode connected to
the + panel and cathode to the MPPT + input white wire) may be used, see wiring diagram.
This diode will protect against panel short and block any voltage on the panel but will slightly
decrease the battery charge current.
• I
F
the optional diode is not installed then shorting the panels when the batteries are
connected may damage the MPPT.
• The lowest Maximum Power Point system voltages are 18V fo 12V batteries, 36V for 24V batteries
and 72V for 48V batteries to ensure full output power.
