Pre-installation
Upon delivery the Solar Charger Unit is installed as follows:
- Gas control active (see functions)
The above functions can be turned off at any time.
Gas control de-activate
1. Unscrew the 4 screws (see diagram) on the Solar Charger Unit and carefully remove the sassing/lid.
2. Disconnect the jumper J6. The gas control is now de-activated.
Installation – Warning: Take care that the Terminals/Poles correspond!!!
The Solar Charger Unit should be placed in close proximity to the battery and be sufficiently protected against the weather. Take care to place
the battery in a well ventilated place. To enable the unit to function properly, the electrical connections should face downwards. To guarantee
that the unit functions properly it must be connected to the solar generator, the lead-battery and the load.
Each part of the system-solar generator, lead battery, load and Solar Charger Unit should have the corresponding power supply. Please check
each component before installation, when in doubt contact a specialist! Take careful attention on the following installation instructions:
1. Connect the battery to the corresponding terminals on the Solar Charger Unit. To prevent the wiring from overheating and power supply
reduction the use of cable/wire 2,5mm² flexible is recommended. Use always fuse to connected to the battery +terminal/pole. Both
components must be installed close together in the same room.
2. Connect the solar panel to the corresponding terminals on the Solar Charger Unit.
3. Connect the load to the Solar Charger Unit. The connection-terminals pictured on the Solar Charger Unit or see diagram.
Temperature sensor Should be attached closed to the battery.
Battery – complete loading The LED’s indicate the level of recharging. The present charging level of the solar panel and possible
disturbances.
Protection against over discharge (LED red)
By over discharge the load is automatically switched off and the LED is red. When the rechargeable battery is recharged the LED does not
illuminate. The rechargeable battery is ready to be used.
The Solar System fails to Function – possible reasons
Battery terminals/poles are wrongly connected: Avoid at all costs!!!
Load terminal/poles are wrongly connected: The apparatus can be seriously damaged before the fuse blows. Batteries contain considerable
amounts of electrical energy. A short-circuit can result in a large build-up of heat leading to FIRE!!
Two LED’s indicate the operating conditions under different circumstances and possible mal-functions in the Solar Charger Unit.

LED red During the day At night Additional note
1 OFF OFF No flow of charging current Deep discharge not active
No flow of charging current Module poled; Consumer short-circuit
Check flat fuse Check flat fuse Remove cause of defect
Load does not work although fuse
o.k.
Charge control defect.
2 ON OFF Flow of charge current
Battery is charging
The green LED reduces luminous intensity
when reaching the charging limit
Strong light of green LED Charge control defect
3 OFF ON Battery empty Load disconnection active
Consumer switched off
No flow of charging current Check poles, interruption
4 ON ON Battery empty
Flow of charge current
Load is automatically switched on after
reaching the minimum charge
