Pic.2 Wiring scheme
1) Install
ESUN PLUS BOOST
in a dry and adequately ventilated place; it must be fixed on a non-flammable surface and
placed
so
to leave an unobstructed space of at least 10cm around the device that allows the cooling by natural air convection.
2) Connect respectively: load, sensor for battery temperature measure (supplied), PV module and, last, the battery as in
the
scheme
Pic.2
.
When
you
connect
the
battery
the
charge
controller
turns
on
and
it
begins
to
work.
Use proper cable sections as indicated in
Pic.2
.
3) ESUN PLUS BOOST recognizes automatically the battery nominal voltage (12V or 24V) and it adapts consequently its
threshworkingolds. The user must configure the kind of battery in use to adequate the right charge voltage (Veoc). You have
to
set SEAL configuration if you use VRLA or GEL sealed batteries, while you have to choose FLOOD configuration if you use
flooded lead acid batteries. If you use lithium-ionn (
Tab.2
).
4) Set the proper load management program to your own application (
Tab.2
).
Testing
Once made the connections as in
Pic.2
it is necessary to proceed with the testing of the system.
1) With the PV module exposed to sunrays, verify that
ESUN PLUS BOOST
is charging the battery reading the values of
charge
current Ipan and Ibatt (see
Tab.1
).
2) To verify that the battery temperature sensor has been properly connected, check on the LCD that at the page
“battery temperature” a reliable temperature value is displayed (
Tab.1
).
3) Verify the correct turning on of the load. If the load is ON only during night, it is possible to simulate the night by
disconnecting temporarily one of the wires of the PV module. With load ON, check the absorbed current by reading in
the proper page of LCD (
Tab.1
).
WARNING!
Do not connect to the
output loads that draw
more
than
15A
as
inverters.
