watts or more. The inverter will shut down if it is overloaded,
and will restart once the overload is removed.
The PROwatt 250 will NOT operate appliances that produce
heat, such as hair dryers, microwave ovens, and toasters.
4.2 Battery operating time
With a typical vehicle battery, a minimum operating time of 5
hours can be expected. In most cases, 5 to 10 hours of operat-
ing time is achievable. Statpower recommends that the operator
start the vehicle every 2 - 3 hours to recharge the battery. Peri-
odically charging the battery will prevent any unexpected shut-
downs of the equipment and will ensure that there is always
sufficient battery capacity to start the vehicle engine.
The inverter may be used either while the engine is running or
turned off. However, the inverter may not operate while the
engine is starting since the battery voltage can drop substan-
tially during cranking.
The PROwatt 250 draws less than 0.1 ampere from the battery
when it is not supplying power to a load. In most cases the
PROwatt 250 can be left connected to the battery when it is not
in use since it draws so little current. If the vehicle will not be
used for several days, disconnect the PROwatt 250 from the bat-
tery.
CAUTION: LOW BATTERY ALARM
