Maximum Power Point Tracker
Operating Instructions
Please read these instructions before use
Important notes:
•
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 12V, 24V or 48V Lithium Iron Phosphate (LiFePO
4
) and confirm the MPPT settings, charge voltages and
currents are correct for your battery system – if in any doubt seek qualified 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 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.
•
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.
•
To enhance Battery and Load protection the MIHV or equivalent and a suitable BMS rated to the maximum
panel power and 170% of nominal battery voltage is highly recommended.

MPPT30-2L General Information:
•
Green LED On – Battery Ok.
•
Green LED Flashing – Battery Low.
•
Green LED Off - Fault Condition
•
This MPPT is designed to auto detect 12V, 24V or 48V battery systems and select a suitable charge regime.
•
The MPPT30-2L is shipped set to Nominal Charge which is the safest setting. If you require, Long Life or
High Capacity Charging then
BEFORE
wiring the MPPT in, follow the
CHANGING CHARGE TYPE SETTING
PROCEDURE.
•
The maximum Saturation voltage is (when set to High Capacity) 14.8V, 29.6V or 59.2V and the Maintence voltage
is 14.1V, 28.2V or 56.4V for 12V, 24V or 48V batteries respectively.
•
The saturation phase is entered following a low battery condition at dawn and is maintained for the rest of the day.
Otherwise Maintenance voltage is applied.
•
Custom 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 threshold before the charger will enter a Saturation charge is 13.9V / 27.8V / 55.6V
