4.OPERATIONS
SUNCONTROL2 charges up to two batteries: one
service battery (B1) and one starter battery (B2), with
priority charging to the service battery.
SUNCONTROL2 will start charging the batteries if the
following conditions are satisfied:
1. The connected Solar Panels deliver a voltage 1V
higher than the voltage of the batteries to be
recharged.
2. Battery voltage higher then 8V.
The Leisure Battery will be charged with the selected
curve.
The Starting Battery will be charged if the following
conditions are satisfied:
• Leisure battery charged between 80% and 100%.
• Starting battery with voltage under 12,5V.
Every charging phase have a maximum run time, with
the exception of the maintenance phase, which
constantly monitors the state of charge and, if
necessary, delivers an impulse current to keep the
battery 100% charged.
NOTE
If the photovoltaic panels interrupt the power supply (during
night, shadowed solar panel, etc. ...) the system goes into Stand-
By mode: LEDs off and self-consumption to the minimum
(<2mA).
