GSR 36/48V
GSR 36/48 is a control circuit for photovoltaic (PV) panels to
batter charge. GSR 36/48 V implement PV panels step up
tension circuit (Step-up) it can so work with PV panels having
a working voltage inferior to the voltage of the batter . In fig. 1
it is possible to find a complete GSR 36/48 V scheme.
The charging circuit of the batter makes the PV module work
in the maximum power point in a voltage range from 2.0V
down to a voltage close to the batter voltage . The batter can
be both 36V and 48V, and the voltage can be changed using a
switch.
The GSR 36/48 can be configured to charge lead-acid batteries
(charge - end voltage, temperature compensated) and lithium-
ion batter (LiFePo) and in this case applies a constant charge -
end voltage with temperature.
There is a LOAD terminal that can be used to control the
activation of an external load at the same voltage of the
batter with a maximum current of 5A.
The LOAD terminal can be configured using a dip switch to
fuction for 24 h/da or it can be set to function onl at night
(SW3).
The LOAD terminal doesn't function in case of low batter
(voltage lower than the low-batter signal- see Tab 3).
Two LEDs on the GSR 36/48 indicate the operational status of
the s stem , a green LED indicates the charging current
delivered to the batter , while an amber/red LED indicates a
low batter condition or overtemperature (see Tab.2).

Electrical connection and plugging
1 ) Set the DIP switch 1 according to the voltage of the batter in use 36 V or 48 V.
If the GSR 36/48 is powered b an incorrect configuration of the dip switch can ruin the
batter or not function properl .
2 ) Set the DIP switch 2 according to the t pe of batter (Pb or LiFePo ) as described in the
following table 1 ( configuration dip-switch) . If the GSR 36/48 is powered b an incorrect
configuration of the dip -switch can ruin the batter or not function properl .
3 ) Set the DIP switch 3 according to the t pe of LOAD expected, 24 h or at night.
4) Install the GSR 36/48 in a dr place , not exposed to rain and adequatel ventilated.
During its operation the GSR 36/48 generate more heat and keep warm , to prevent entr
into operation its overtemperature protection ou need to keep a clear space around it so
that it can circulate air that helps cooling.
5) Make the electrical connections as shown in Fig. 2,
First of all connect the Load, then the batter and last the PV module. If this sequence is
respected the GSR ma signal a batter error( red led stable).
be sure to use the electric cables to the appropriate section of current that must flow . As
soon as the batter is connected both LEDs light up for a second to report good start to
the charge controller.
6 ) Test the installation just connected b verif ing that the s stem charges the batter .
With the PV module exposed to good light , verif that the green LED is flashing, it
indicates that charging current is flowing into the batter . For a closer examination of the
proper functioning of the regulator is recommended to check with a voltmeter while
charging the batter voltage measured at the terminals of the PV module PV + and GND is
close to the maximum output voltage of the photovoltaic module in use ( see the
datasheet module to locate the voltage of maximum power t picall referred to as Vmp .
During this test, make sure the batter has a voltage lower than the voltage - end load
set.
