WARNING: This inverter is not compatible with devices that have a
capacitive power supply; due to their design they will not work with the
simulated AC voltage (modified sine wave) of this inverter. Such power
supplies are no longer sold from new in Europe due to their reliance on pure
sine wave AC and are fairly rare. They do not meet current European safety
standards but if you suspect your device has such a power supply, make
sure you monitor the device when first connected. If it is a battery charger
that contains a rechargeable battery of any type it is recommended not to
try it due to the possibility of damage to the batteries.
WARNING: If the inverter is constantly running at a very high temperature
or is shutting down in use, it is possible the device connected to the inverter
is not ideally matched and should not be connected. Always monitor the
inverter and mains device when connected for the first time for the first 5
minutes or so to ensure both are working correctly at normal temperatures,
then check on the device every half hour for the first 2 hours. Once the
device is confirmed as compatible mark it so its compatibility is recorded.
WARNING: The mains sockets fitted to the inverter are a universal type
which accommodates a wide range of world mains plugs. It is important
when using devices fitted with a non-UK or European plug that you check
the device is compatible with 230V 50Hz. This is especially important for
devices intended for the US market; these will normally be 120V 60Hz
only and must not be connected. Only if the rating label of the product
specifically states a wide input voltage and dual mains frequency, for
example '100-240V - 50/60Hz' can they be used.
IMPORTANT: The inverter is reliant on being connected to a DC power
source sufficient to power your AC mains devices. It is not a fault with the
inverter if the current is inadequate to power your mains devices.

IMPORTANT: If you are using an RCD with the inverter check that the
inverter is operating normally. As with all RCDs use the test button to make
sure it is operating correctly before use. If the RCD is not operating normally
with an inverter this does not indicate a fault with the inverter or RCD and
is likely caused by either the modified sine wave output or lack of neutral/
earth bonding you would get from normal domestic sockets.
IMPORTANT: The inverter may shut down as a vehicle engine is being
started due to the high electrical current required by the vehicle starter
motor. Ideally turn off the inverter before starting the vehicle.
Notes
• The inverter simulates mains AC voltage using a modified sine wave
(Fig. D). A small number of devices may not be compatible with this
type of AC waveform. Most resistive load devices (kettles, filament
bulbs etc) are compatible. Inductive loads, typically those that have
electrically powered moving parts or have circuit boards with electronic
components, are more likely to be incompatible. These have components
that make use of magnetic fields and often require a high starting current
as well as being more selective about the AC wave form. Generally
even domestic mains sockets don't output pure sine wave AC but their
waveform is closer to pure sine wave than a modified sine wave inverter.
Many devices are designed to work with AC wave forms that are not
pure sine wave, so most devices are compatible with modified sine
wave output
• Some inductive load devices may consume slightly more current or
produce more noise with modified sine wave AC compared to pure sine
wave AC
• Some devices have huge starting current requirements which means
even if the average power consumption is well within the inverter's rating
the device will not be compatible. Pumps and compressors typically have
the highest starting current requirements (a refrigerator is a common
device of this type). Generally an inductive load with the same wattage
power as a resistive load is less likely to be compatible due to starting
current requirements although some resistive loads still have higher
starting current requirements like filament bulbs
• If an inductive load device will not function at all with the inverter, or
is not functioning correctly, connecting a resistive load device with the
inductive load may enable it to function normally. A small lamp with a
filament bulb may be suitable as a resistive load
• DO NOT use this inverter for sensitive devices such as medical
equipment or any other critical or calibrated electronic device that may
not be compatible with modified sine wave AC
• When used with AV devices, it is possible additional background noise
will be heard in use and possible video distortion or interference. This
could be due to many reasons, including interference from the inverter
or vehicle electrics as well as the modified sine wave AC effecting
components in the device. It is possible such a device simply will not
be compatible with a modified sine wave inverter, and a pure sine wave
inverter will be required for the device to work optimally
• Some devices, including laptops, mobile phones, and handheld electronic
devices, have AC power supplies to generate DC that the main unit
requires to operate or charge its battery. It is more efficient for such
devices to be charged using a 12V charging lead (possibly supplied with
the unit) as this eliminates the conversion loss from converting 12V DC
to high voltage AC in the inverter and then high voltage AC back to low
voltage DC in the AC power supply
• Some appliances (televisions, stereos, motors, neon lights etc) may
require a much higher starting power than their rated power. If the
appliance will not start, the maximum output of the inverter has been
exceeded. To reduce the total load on the inverter it may be possible to
start the device by turning off other devices connected to the inverter
and then powering them up again, after you have started the device that
needs a very high starting current. If the inverter switches off due to high
starting current demands, this does not indicate a fault
• When checking AC output from an inverter with a multimeter, unless the
multimeter has a true RMS feature, it will give a low voltage reading from
the output of a modified sine wave inverter. This is normal and not an
indication that the inverter or multimeter is faulty
