MPPT30-2-R8
Important notes:
• This MPPT should only be operated with a suitable battery connected.
• To further protect sensitive and or expensive loads we strongly recommend the use of our MIHV
devices on MPPT installations.
• Before any maintenance ensure that the panels are disconnected or de-energised.
• This equipment must be installed by qualied personnel only and incorrect wiring can cause
re, 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 conrm the MPPT settings,
charge voltages and currents are correct for your battery system – if in any doubt seek
qualied advice!
• Use only PV Systems with open circuit voltage below 95V.
• 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 ammable 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.
• The lowest Maximum Power Point system voltages are 18V for 12V batteries, 36V for 24V
batteries and 72V for 48V batteries to ensure full power.

MPPT30-2 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 30-2 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 oat 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 oat 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.
