MODULE
1) Install WMarine10 in a dry and adequately ventilated place; it has to 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 fig. 2. When you connect the battery the charge controller turns on and it begins to work.
Use proper cable sections as indicated in fig. 2.
3) WMarine10 recognizes automatically the battery nominal voltage (12V or 24V) and it adapts consequently its working
thresholds. The user must configure the kind of battery in use to adequate the right charge voltage (V
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 (fig. 4).
4) Set the proper load management program to your own application (fig. 4).
Testing
Once made the connections as in fig. 2 it is necessary to proceed with the testing of the system.
1) With the PV module exposed to sunrays, verify that WMarine10 is charging the battery reading the values of charge
current I and I (see fig. 3).
PAN BAT
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 (fig. 3).
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 (fig. 3).
