Tundra HTS3000(T) - Manual (Page 23)

HTS(T)-1800_3000-GD-0114-EN 11
If the voltage drops lower than 11.0 Volt for HTS (11.5 Volt for HTST), the low battery
protection alarm will sound and battery sign on the remote will flash.
If the voltage drops below 10.5 Volt for HTS (11.0 Volt for HTST), ERR LOW code will
display on the remote and the inverter will shut down automatically. This protects your
batteries from being over-discharged. The inverter will automatically restart when the
input voltage will rise above 13.2 Volt for at least 2 seconds.
The inverter also has a high voltage shut down. If the voltage exceeds 15 Volt, the high
battery warning alarm will sound, the ERR HIGH code will display on the remote and the
inverter will shut down until the input voltage drops below 15 Volt. This protects the
inverter from excessive input voltage. While the inverter incorporates protection against
over voltage, it may still be damaged if the input voltage exceeds 16 Volt.
4.2 Trouble loads - Television & CB radio interference
CB and television are designed to catch “frequencies” emitted by different devices. Inductive loads such as
electric motors (ex: fridge compressor) can emit a magnetic field strong enough to be interpreted as a signal by
television and CB radios.
If this occurs, the following steps may help eliminate the problem:
 Disconnect all inductive loads while using the TV or the CB Radio
 Move the television as far as possible from your inverter
 Use an extension cord to help dissipate the strength of the magnetic field.
 Make sure both DC battery cables are tied up together as much as possible (from the inverter to the batteries)
4.3 Trouble loads - Microwave
The power rating advertised on microwave ovens represents the cooking power which refers to the power being
delivered to the food being cooked. The actual operating power requirement is approximately 40 to 100% higher
than the advertised cooking power (i.e.: 600w microwave could consume +/- 960w). The actual power
consumption is usually stated on the back of the microwave. If the operating power requirement cannot be found
on the back of the microwave, check the owner's manual or contact the manufacturer.
* NOTE: Amperage x Voltage = Wattage (i.e.: 8A x 120Vac = 960W)
4.4 Trouble loads - Tools
The power rating of certain tools like circular saws or pumps refers to the power required during normal
operation. The actual operating power requirement at start up may be up to 300% higher. In a tool application, it
is recommended to buy an inverter more powerful than the tools seem to require, in order to be able to support
the start-up surge required by certain tools.
