SOFT START TECHNOLOGY
The soft start technology built into this inverter protects the unit from delivering too
much AC power at once by gradually increasing the AC voltage pushed out.
To
make sure that you are utilizing this feature, turn on the appliance being used
before turning on the inverter. This is especially necessary for equipment that has
an inductive load or electrical motor
.
OUTPUT VOLTAGE & WAVEFORM
The electrical waveform output of this inverter is a pure sine wave, which has the
same quality as utility and/or domestic power
.
This type of waveform is suitable for
most electrical devices, appliances and tools. This pure sine wave unit provides
more capabilities than modified sine wave inverters because it is a cleaner form of
power. The pure sine wave also effectively reduces the noise produced while using
appliances.
PROTECTIONS IN THE INVERTER
1. Input under-voltage alarm: When the input DC voltage is lower than 9.8V
(19.6V/39.2V), the buzzer will whistle intermittently to remind that the inverter
will go into the under voltage protection.
2. Under voltage protection: The inverter will automatically shut down when the
input DC voltage is lower than 9.5V(19V/38V). The buzzer will whistle
continuously and the green light is off, red light is on. Please turn off the
inverter and use it after recharging the battery.
3. Over voltage protection: The inverter will automatically shut down when the
input DC voltage is higher than 16V(32V/62V). The buzzer will whistle
continuously and the green light is off, red light is on. Please turn off the
inverter and adjust the input voltage to the admissible range.
4. Overload protection: The inverter will automatically shut down when the load is
higher than the rated power. The buzzer will whistle continuously. Turn off the
inverter and resume to normal operation after taking away the excessive load.
5. Short-circuit protection: The AC output will automatically shut down when short
circuited. It will automatically reset after the problem is solved.
6. Thermal protection: The unit will get hot during operation. If the temperature is
higher than 149°F, the inverter will automatically shut down. Then the buzzer
will whistle continuously and the green light is off, red light is on. Please turn
off the inverter, and continue using it after the temperature goes back to
normal naturally. Meanwhile find out the factors causing the fault, such as
ventilation, ambient temperature, vent, load power etc. It can avoid similar
things from happening again.
**NOTE**
The numbers in the parenthesis are for 24V and 48V models. In the case of
over voltage, under voltage and thermal protection, the inverter will shut down. When
the inverter is in the OFF position, the inverter doesn't consume battery current.
