200W Solar Charger
Maximum Power Point Tracker
Operating Instructions
Please read these instructions before use
This revolutionary maximum power point tracker solar charger was
designed using the technology that won GSL Electronics the prestigious
“2008 EDN Innovation award”. A simple, compact and low cost
alternative. Ideal for charging batteries with the new low cost and high
efciency grid type panels.
Important:
• Use only PV Systems with open circuit voltage below 55V and a V
MP
no less than 17V for 12V Charging
and 34V for 24V Charging.
• Use wires suitable for at least 15a, 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 15A 24V fuse would do.
• Locate the PV fuse (PVF) as close to the MPPT as possible (10A 60VDC Rating). PVF only mandatory
with high power panels.
• If used, this fuse is optional, locate the output fuse (of) as close to the MPPT as possible
(15A 24VDC rating).
• Before connecting battery always check battery and PV panel polarity.

Basic Wiring Instructions:
MPPT12-1 General Information:
• This MPPT is designed to auto detect 12V and 24V battery systems and select a suitable
charge regime.
or 24V batteries respectively.
• The absorption phase is entered following a low battery condition and is maintained for
approx. 1.5 hours.
.
• This MPPT has a built in multilevel over temperature protection to improve product reliability
while maximising output power availability.
• The peak maximum output power is 250W and the continuous output power is 150W on 12V
systems and 200W on 24V.
over 20%.
• The fuse PVF can be replaced by a suitably heatsinked 20A 60V schottky diode ( its anode
connected to the + panel and cathode to the MPPT white wire). This diode will avoid a small
drain during night time (approx. 0.04A ) as well as protect against panel short but it will also
slightly decrease the battery charge current.
Note: First start up may take up to one minute.
