General features of SkyTronic inverters
• high performance at low heat production
• 50Hz stable output frequency
• regulated 230V output voltage
• protection against short circuit and overheating
• with SkyTronic battery protection system. If the battery voltage drops to 10.5V (21V for
24V batteries) the inverter emits an alarm signal. If the battery voltage drops even further, the inverter
shuts off automatically. This advanced protection system avoids to over discharge the battery.
WARNING
SkyTronic inverters supply an output voltage of 230V which is as dangerous as the domestic mains
voltage! Therefore only use double-insulated devices and replace immediately leads that are in bad
condition. Don’t expose the inverters to humidity and place them in a well ventilated area. The inverters
with an earth connector can be connected to a grounding point such as a metal part of a boat or the car
chassis.
Important!
Under full load, high current is flowing through the battery cables. Therefore it is recommended to use
only the supplied cables and no extension cables in order to avoid unacceptable voltage losses. If
necessary, use an extension cord in the 230V circuit to the connected unit. To comply with the legal
standards, the inverter may only be used with the supplied low voltage cables. Do NOT extend them.
The connected battery must be in good condition and fully charged. After some time, it may be necessary
to start the car or boat in order to recharge the battery. At that moment, the inverter must be switched
OFF beforehand in order to avoid damage due to excessive battery voltage.
On/off switch
Connect the inverter to the battery (red is positive, black is negative). Make sure that all connections are
of good quality. First switch on the inverter and afterwards the unit to be powered. Switch off in reverse
order.
Thermal protection
All SkyTronic inverters are protected against thermal overload. If the temperature of the inverter rises
above 55°C, the protection circuit is automatically activated and the unit is switched off. First switch off
the connected unit and then the inverter. Let the units cool down before you switch them on again. Check
if the cooling fan is not obstructed and make sure that there is sufficient air flow around the unit.
TROUBLESHOOTING
If you experience problems with appliances not operating correctly when there are two or more devices
connected to the same circuit, the only remedy is to disconnect one of the units to reduce the load. If
the inverter overheats when the load is at the rated maximum, try running the vehicle engine while
running the inverter. (REMEMBER to switch OFF the inverter when starting the enginee.) This will boost
the battery voltage allowing the inverter to operate more efficiently, allowing use of the inverter for
longerperiods of time in high load applitcations.
