It displays the battery voltage (V
BAT
), the charge program currently selected (either SEAL or FLOOD),
the day/night status detected by the PV module. The load icon, if ON, indicates that the load is power
supplied.
button
It displays the current (I
PAN
) of the PV module. We remind that the current delivered by the PV module
depends on its state of sun-lighting and on battery charge status. With charged battery (Vbatt>14,4V
@12V o Vbatt>28,8V @24V) and even with a good lighting of the PV module, you have low recharge
currents since the regulator limits such current so to avoid the battery overcharge.
button
PV module voltage (V
PAN
).
button
It displays the power in watt actually delivered by the PV module.
button
It displays the counter of energy that is delivered by the PV module in KWh. It is possible to reset this
measure pressing simultaneously the buttons
for 2 seconds.
button
It displays the recharge current inside the battery (I
BAT
).
button
It displays the battery temperature that is currently measured by the temperature sensor connected to
WRM20.
button
It displays the current that is currently delivered to the load; even if in this screen the load icon is on,
this does not mean that it is effectively power supplied; in fact the load is controlled according to the
management load program that is currently set.
button
It displays the power that is currently delivered to the load in watt.
button
It displays the Energy counter in KWh consumed by the load. It is possible to reset this counter
pressing simultaneously the buttons
for 2 seconds.
