GSR 36/48V
Technical manual
Model 36/48
Electrical connection and plugging
1 ) Set the DIP switch 1 according to the voltage of the battery in use 36 V or 48 V.
If the GSR 36/48 is powered by an incorrect configuration of the dip switch can ruin the
battery or not function properly.
2 ) Set the DIP switch 2 according to the type of battery (Pb or LiFePo ) as described in the
following table 1 ( configuration dip-switch) . If the GSR 36/48 is powered by an incorrect
configuration of the dip -switch can ruin the battery or not function properly.
3 ) Set the DIP switch 3 according to the type of LOAD expected, 24 h or at night.
4) Install the GSR 36/48 in a dry place , not exposed to rain and adequately ventilated.
During its operation the GSR 36/48 generate more heat and keep warm , to prevent entry
into operation its overtemperature protection you 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 battery and last the PV module. If this sequence is
respected the GSR may signal a battery error( red led stable).
be sure to use the electric cables to the appropriate section of current that must flow . As
soon as the battery is connected both LEDs light up for a second to report good start to
the charge controller.
6 ) Test the installation just connected by verifying that the system charges the battery.
With the PV module exposed to good light , verify that the green LED is flashing, it
indicates that charging current is flowing into the battery. For a closer examination of the
proper functioning of the regulator is recommended to check with a voltmeter while
charging the battery 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 typically referred to as Vmp .
During this test, make sure the battery has a voltage lower than the voltage - end load
set.
