8. Frequently Asked Questions and Answers(FAQ)
●How to check the state of charge?
The battery icon display on the LCD display shows the battery level and charge status.
●
How to use the product to charge other electronic
devices?
(1) Check the user manual or search for such information online to learn about the
charging parameters of the electronic devices.
(2) Check the power of each output port. For example, the maximum rated output power
of the AC output port is 300W, This means that if the power of the connected electronic
device exceeds 300W for a long time, the inverter will turn off the output.
●What is the depth of discharge (DOD)?
To prolong the battery life, the product has a DOD setting to 90%, which means that only
90% of the battery capacity can be discharged, and retain 10% to avoid damage to the
battery due to excessive discharge.
●Can it charge and discharge simultaneously?
Yes, but it is not recommended to charge and discharge at the same time in order to
protect the battery life.
●Can it be charged by using 2 solar panels in series?
Yes, just make sure the total open circuit voltage (VOC) of the solar panels are less than
40V, Otherwise it may trigger the charging overvoltage protection or cause damage.
●How to extend the using time of CPAP ?
Recommend to turn off its humidifier, heater, and set a lower pressure.
●
50Hz/60Hz frequency switching (factory setting: 60
Hz).
Step 1:
Press the power button to turn the product on, then press the DC and AC
button at the same time. The LCD will illuminate and display the current frequency (50Hz
or 60Hz). Release the button and continue to the next step.
Step 2:
Press and hold the DC button or AC button to select 50Hz and 60Hz. The
frequency displayed on the LCD will change accordingly.
