when in use, please discontinue use immediately and contact technician or retailer
-
This inverter is design to be maintenance free, but requires occasional attention as dust may build
up after period of time. To clean dust off, please switch off power from inverter and unplug AC
plug. Carefully clean unit with a dry cloth. Do not use a wet cloth or cleaner
-
Check and tighten the DC input terminal on regular basis, as if the inverter is stored in an
environment with a lot of vibration (eg in a vehicle) it may cause the hand screw to become loose
-
Keep out of reach of children

Low input power protection warning
– the input power is below 10.8V± 0.2V for 12V input inverter
and 21.6V± 0.4V for 24V input inverter. This indicates the power bank is running low or DC power supply
is insufficient, requires charging or boost of DC power supply.
Low input power protection critical
– the input power is below 10.2V± 0.2V for 12V input inverter and
20.4V± 0.4V for 24V input inverter. This indicates the power bank or DC power supply is critically low, to
protect the battery and dc power supply from over drained, inverter will switch off AC output.
Input over power protection
- the input power is over 15.5.2V± 0.2V for 12V input inverter and
31V± 0.4V for 24V input inverter, the inverter will shut the output off to stop inverter from damage by the
extra input power.
Over heat protection
– when inner temperature exceeds 45°C, temperature controlled fan will
automatically switch on to try to cool down the unit. If unit can not be cooled down due to high ambient
temperature or any other reason and inner temperature reaches 75°C, the inverter will automatically shut
down the output to stop inner temperature creeping higher to cause damage to components.
Short circuit protection
– in case of short circuit occurs, AC output will be switched off to eliminate
shock hazard to user.
Over load protection
– in case of overload occurs, AC output will be automatically switched off to
protect inverter from damage.
