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 600W, This means that if the power of the connected
electronic device exceeds 600W 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.
