Excess Energy Management Function EEM
The controller provides a built-in excess energy management function. This
function, in combination with especially designed loads (e.g. Phocos DCL DC
voltage converter , Phocos BCM DC battery charger), allows to make use of excess
energy which would be lost otherwise because of the overcharge protection of
the battery. A better utilization of the solar system is the benefit. Also the battery
treatment is improved because more energy comes directly from the solar panel
instead of the battery. Ask you dealer about available loads that can make use
of excess energy.
To connect your Excess Energy load with the controller, see picture 8 (signal
wires).
The controller is preset to Mode 1 from the factory. Use Programming Menu 2.
to change the setting (see back page).
In case of doubts which mode to choose, consult your dealer because this has
to be evaluated depending on the battery used.
current). Mode with lower disconnection point. Battery is cycled deeper, this can
shorten battery lifetime.
Mode 3:
Disconnect at 11.0 V to 12.2 V depending on load current and previous
charging cycles. This adaptive mode leads to longer lifetime of the battery because
it allows recovery of the battery by full recharge. Maximum battery life.
Mode 4:
Disconnect at 11.5 V fixed setting. Appropriate if bypass loads draw
current directly from battery.
Mode 5:
Disconnect at 11.0 V fixed setting. Appropriate if bypass loads draw
current directly from battery. Mode with lower disconnection point. Battery is
cycled deeper, this can shorten battery lifetime.
