MPPT60-1 General Information:
• Green LED On – Battery Ok.
•Green LED Flashing – Battery Low.
• This MPPT is designed to auto detect 12V or 24V battery systems and select a suitable charge
regime.
• The MPPT 60-1 is shipped in a sealed battery setting which is the safest setting but if your batteries are
vented or Lithium Iron then, BEFORE wiring the MPPT, follow the CHANGING BATTERY TYPE
SETTING PROCEDURE.
• The maximum absorption voltage is 14.5V or 29V and the float voltage is 13.5V or 27V
for 12V or 24V batteries respectively.
•The Absorption Mode is entered following a “low battery condition” at dawn and that mode is
maintained for the remainder of the day. If the battery is not in a “low condition” at dawn then
the Maintenance (Float) Mode is entered and that mode is maintained for the remainder of
the day.
•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 24V systems and 850W in 12V systems.
The output current is limited to 60A.
•Can now be installed in parallel on the output for increased charge current. Multiple chargers on
separate solar
The MPPT60-1 is designed to charge lead acid and lithium batteries from photovoltaic panels.
Silicon based panels such as monocrystalline, polycrystalline and amorphous are suitable.

Important notes:
• This MPPT should only be operated with a suitable battery connected.
• To enhance Battery and load protection the use of the MIHV or equivalent is recommended
• Before any maintenance ensure that the panels are disconnected or de-energised.
• Use only PV Systems with open circuit voltage below 84V
• 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 or 24V Lead Acid or Lithium batteries and confirm the MPPT settings,
charge voltages and currents are correct for your battery system – if in any doubt seek
qualifed advice!
• Use wires suitable for at least 80A, 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 80A 60VDC fuse would do.
• Before connecting the battery always check the battery and PV panel polarity.
• Optional Diode A suitably heatsinked schottky diode rated at or above 80A 60V (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.
WARNING
• DO NOT Disconnect battery and/or load whilst charger is operating. Disconnect charger
from the PV first
• IF the optional Diode is not installed then shorting the panels when the batteries are
connected may damage the MPPT
• Lithium batteries must have a battery management system with built in under votlage
and over voltage protection.
• The lowest Maximum Power Point system voltages are 18V for 12V batteries or 36V for 24V batteries
to ensure full output power.

Changing Battery Type Setting Procedure
1.Ensure all the MPPT wires are disconnected. Disconnecting PV first.
2.Remove the 5 front panel screws and the move the front panel ajar. Then remove 1 middle rear screw
on the back panel (bottom middle below fan) then slide out bottom cover – see Figure 1.
3.Locate connector J4 – see zoom window in Figure 1.
4.Move link on J4 to vented position or Remove link for Lithium batteries – see Figures 2 ,3 ,4.
5.Slide in the cover and fit front panel carefully, secure the front panel again with the 5 screws and
the 1 rear screw.
•The above procedure can be repeated to revert a different battery chemistry setting – see Figure 3.

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 eff ciently charge the
batteries from relatively high voltage, say 24V batteries from 40Vmp panels.
2. Less interference and more accurate voltages during absorption and f oat.
Q: What sorts of loads can I power with the MPPT60-1?
1.The maximum bulk charge current with the MPPT60-1 on a 12V battery and 800W panel is
approximately 60A, so you can expect about 200Ah per day which means a 200W load for
about 10 hours daily.
2. Following the same reasoning with a 24V 1600W panel the MPPT60-1 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 specifically 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 180Ah.
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 the battery reaches the float 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 a conventional solar regulator during
the absorption and float 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 first 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 may also help and finally you can try adding ferrite clamps.
