7.2 Fence voltage indicator
The fence energiser measures the fence voltage and briefly blinks the light indicating the fence voltage after each
impulse (approx. 7 kV: green; 5 kV: green; 3 kV: yellow; 2 kV: red). If none of the lights blinks, the fence voltage may
be insufficient. The fence should be improved or the Full Power operating mode chosen.
7.3 Battery voltage indicator
The fence energiser measures the battery voltage and indicates it with the light bar as follows:
Battery indicator light Battery level
Status
Green (upper)
75–100%
Battery OK
Green (lower)
50–75%
Battery OK
Yellow
25–50%
Battery should be charged.
Red
Under 25%
Charge the battery ASAP.
Red blinks
Discharged
Risk of permanent battery damage, charge immediately! If deep
discharge protection is active, the fence output has been reduced.
When the battery is low, the MODE light is not ON continuously but blinks briefly in the rhythm of the fence impulse
to save power.
7.4 Use with solar panel (optional accessory)
The battery can be charged with a solar panel if you purchase the Olli 20 W solar panel kit. Connect the white solar
panel connector to the white connector on the battery cable. Protect the connection against moisture. Connect the
fence energiser to the battery (see Section 6.4).
The charging current now flows from the solar panel to the battery through the energiser. The energiser protects
the battery from overcharging. Battery charging and overcharging protection are also active while the fence ener-
giser is in the standby mode.
The fence energiser will not operate on the solar panel alone; the battery must always be connected.
Note! When the battery is charging, its charge level cannot be reliably deduced from the energiser’s battery indica-
tor. The battery charge may appear to be higher than it actually is. Therefore, when using a solar panel, the battery
charge level indicator works best when it is dark or when the panel is disconnected. Be sure to read the operating
manual of the OLLI 20 W solar panel kit as well.
7.5 Battery deep discharge protection
The energiser has built-in battery deep discharge protection. When the battery voltage drops below ca. 11.8 V,
deep discharge protection delays the destruction of the battery by lowering the energiser’s current consumption.
The fence energiser does not switch off completely but gives low energy impulses with longer intervals. The bat-
tery signal light blinks rapidly.
The voltage of a battery in poor condition can sometimes be lower than normal, even if the battery is still usable
to some extent. Deep discharge protection will prevent the use of such a battery. In such cases, deep discharge
protection can be switched off:
1. Start the fence energiser and set it to the Full Power mode.
2. While the fence energiser is operating, disconnect its black battery clamp from the battery’s minus pole.
3. Repeat the following steps three times:
4. Wait 10 seconds.
5. Reconnect the battery clamp to the battery. The fence energiser starts.
6. When the red impulse light has blinked three times, disconnect the battery again. Return to step 4.
Deep discharge protection is now deactivated. To indicate this, the energiser blinks its yellow battery light three times
before the start of fence impulses every time the battery is connected. The low battery voltage warning functions in
the normal manner, but the energiser’s power and pulse interval do not change when the battery voltage drops.
When battery voltage drops below approx. 8.5 V, the energiser switches off regardless of deep discharge protection.
To re-activate the deep discharge protection, repeat the deactivation steps.
