Important notes:
• Only qualied electricians or technicians who are familiar with solar system design and wiring
practices should install this product.
• Use only PV Systems with open circuit voltage below 180V and a minimumV
MP
of 16V for 12V
batteries, 32V for 24V batteries and 64V for 48V batteries.
•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, vented or calcium 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 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.
• The MPPT preferred mounting position is vertical with the fan on the lower side and at least 50mm
clearances on top and bottom.
• 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. (Always use DC fuses rated to match your
batteries and charging situation.)
• Before connecting the battery always check the battery and PV panel polarity.
• The MPPT30HV chassis must be properly earthed - if in any doubt seek qualied advice!
(We Recommend at least one of the one of the mounting xtures is tted with an external star
washer against the heatsink.)
• Make sure that if the electrical circuit requires grounding that it is only grounded in one point.
Ground on multiple points, such as on PV and Battery, may compromise MPPT Protections.
• Make Sure that the connection sequence is as follows. 1st “Panel -”, 2nd “Panel +”,
3rd “Battery -”, 4th “Battery +” and nally 5th “Load -”
MPPT30HV General Information:
• Green LED On – Battery voltage above nominal.
• Green LED Flashing – Battery voltage below nominal.
• This MPPT is designed to auto detect 12V, 24V or 48V battery systems.
• The MPPT30HV is shipped in a sealed battery setting. But if your batteries are vented or
calcium then, BEFORE wiring the MPPT in, follow the CHANGING BATTERY TYPE
SETTING PROCEDURE.
• This MPPT has an automatic output power derating to 70°C to improve product reliability
while maximising output power availability.
• The maximum continuous output power is 1800W in 48V systems, 900W in 24V systems
and 450W in 12V systems. The output current is limited to 30A.\
• For additional safety and reliability we recommend the MPPT30HV to be used in
conjunction with the MIHV240.

MPPT FAQs
Q: What is an MPPT?
MPPT stands for Maximum Power Point Tracker and is a specialized converter designed to
maintain the PV voltage at the level in which it delivers maximum power to the load or battery.
The panel’s nominal output power can only be obtained with the use of an MPPT.
Q: What are the GSL MPPT’s advantages compared to standard solar regulators?
1. Suitable for lower cost non battery type PV since the MPPT can efciently charge the
batteries from relatively high voltage, say 24V batteries from 40V MPP panels.
2. Less interference and more accurate voltages during absorption and oat.
Q: What sorts of loads can I power with the MPPT30HV?
1.The maximum bulk charge current with the MPPT30HV on a 12V battery and 400W panel
is approximately 30A, so you can expect about 100AH per day which means a 100W load
for about 10 hours daily.
2. Following the same reasoning with a 24V 800W panel the MPPT30HV will supply a daily
load of 200W for about 10 hours.
3. Following the same reasoning with a 48V 1600W panel the MPPT30HV will supply a daily
load of 400W for about 10 hours.
Q: Why are MPPT not more common in standalone solar systems?
Until now and despite their overwhelming advantages MPPTs have not been commonly used
in standalone solar systems because of cost. The new GSL MPPT specically addresses this
issue making economic sense in a wide range of solar systems.
Q: What sort of batteries should I use?
1. A deep cycle battery is a must due to the cyclical nature of the solar system with a
recommended battery capacity of at least a few days of running your load.
2. A larger battery will not only give longer run time during low light but also will be able to
avoid available PV power being unstored such as when battery reaches the oat stage.
Q: How do PV temperatures affects charge current?
Temperature increase brings down the PVs maximum power point voltage reducing the
MPPTs current gain available. In principle at 25C it is possible to achieve 30% gain but at
40C, a more realistic average temperature, about 20% is still available.
Q: What happens at low PV currents?
The MPPT will outperform the conventional regulator above 3% of nominal panel power.
Below 3%, about 10W in a 400W panel, the MPPT will have a slightly lower output current
than a non MPPT.

Q: Is interference possible? and If so what do I do?
GSL’s MPPTs produce far less interference than conventional solar regulator during
the absorption and oat stages, that is during most of its operating time, and its
designed to comply with local and international EMI standards however some
interference is still possible. If interference occurs rst try and reorient the aerial or move
the sensitive equipment away from the MPPT wires. Ensure the MPPT chassis is grounded.
Grounding a battery terminal (but only ground one point in cirucit do not ground both input and
output) may also help and nally you can try adding ferrite clamps.
