What type of battery should I use (automotive or deep cycle)?
Small Inverters (up to 500W)
Most leisure and marine batteries will provide an ample power supply for 30 to 60 minutes even
when the engine is off. Actual time may vary depending on the age and condition of the battery, and
the power demand being placed on it by the equipment being operated by the inverter. If you use
the inverter while the engine is off, you should start the engine every hour and let it run for 10
minutes to recharge the battery.
Larger Inverters (500W and above)
We recommend you use deep cycle batteries which will give you several hundred complete
charge/discharge cycles. If you use the normal vehicle starting batteries they will wear out after
about a dozen charge/discharge cycles. If you do not have a deep cycle battery, we recommend that
you keep the engine of your vehicle running whilst using the power inverter.
When using the inverter with a deep cycle battery, start the engine every 30 to 60 minutes and let it
run for 10 minutes to recharge the battery.
When powering appliances with high continuous load ratings for extensive periods, it is not advisable
to power the inverter with normal car battery. If the car battery is used for an extended period, it is
possible that the battery charge may be drained to the point where the battery has insufficient power
to start the vehicle. In these cases, it's a good idea to have an extra deep cycle battery installed for
the inverter (installed close to the inverter), cabled to the original battery/alternator. It is also
recommended that a suitable battery isolator should be installed between the two batteries.
