Inverter Operation
1. When properly connected to a 12V port, the LED light will turn BLUE, indicating the inverter is ready.
2. Plug the device you want to operate into the AC outlet or USB port and switch them on (if necessary).
Operating Guidelines
As the battery is depleting, the voltage begins to fall. When the KRP150 senses that the voltage
at its DC input has dropped to 10.5V, the inverter automatically shuts down and the LED light will change to
RED, indicating a fault. This prevents damage to your devices and from completely draning the battery. Turn
off any devices that the KRP150 is powering.
If an AC device is rated higher than 150W and plugged into the KRP150, the inverter will shut down. The LED
light will alternate from BLUE to RED. If the KRP150 exceeds a safe operating temperature, due to insufficient
ventilation or a high-temperature environment, it will automatically shuts down. The RED FAULT LED light
will turn on.
Should a spike in DC voltage above 15V the KRP150 automatically shutdown. The RED FAULT LED light comes
on.
Battery Operating Time
Operating time will vary depending on the charge level of the battery, its capacity and the power level drawn
by the particular AC load, USB load, or combination of both. With a typical vehicle battery and a 80W load,
has an operating time of 4 to 5 hours or more can be expected.
When using a vehicle battery as a power source, it is strongly recommended to start the vehicle every hour
or two to recharge the battery before the capacity drops too low to operate or to start the engine. The KRP150
can operate which the engine is running, however normal voltage drop can occur while cranking the engine,
which may cause the inverter to turn off due to low voltage input.
