Operating Instructions
MPPT30-2-R8
This revolutionary maximum power point tracker solar charger was designed using the
technology that won GSL Electronics the prestigious EDN Innovation Awards 08’ and 09’
and the Greentech Consensus Awards 09’. A simple, compact and low cost alternative.
Ideal for charging batteries with the new low cost and high efciency grid type panels.
The MPPT 30-2 is designed to automatically charge 12V, 24V and 48V sealed and vented
lead acid batteries from silicon based PV panels such as monocrystalline, polycrystalline
and thin lm. It has a built-in Load Low Voltage Disconnect congurable as a Dawn to Dusk
switch. It can be connected to the MCM for remote control and full system parameter logging
and display.

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 qualied 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 conrm the MPPT settings, charge voltages and currents are correct for your battery system – if in any doubt seek qualied 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.

BASIC WIRING OPTIONS:
Permanent Load Connection
(Figure 1):
Simplest wiring option where the
load is permanently connected
and the batteries are not
protected from overdischarge.
Wiring With Low Voltage
Disconnect (Figure 2) :
This option protects the
battery from overdischarge by
disconnecting the load. The
LVD option disconnects the
load when the battery voltage
drops below 0.85 of nominal
voltage to protect the battery
from damage. The load
reconnects when the battery
voltage exceeds 0.95 of
nominal voltage. This feature
will not trigger during short
transients. LVD load is 30A
continuous or 50A transient.
