9. Examples of loads
(1) 12V / 25A, 12V / 3A, cigarette lighter port, USB and type C output port are suitable for
most products in the market, but some products may trigger overcurrent protection if there
is a large current impact at the moment of starting.
(2) The power of electrical products used for AC output should be less than 2000W.
According to the different electrical products, when the rated power is less than 2000W,
some air conditioners, motors and other devices that need instantaneous high current
when starting may trigger overcurrent when the ratio of peak value of rated current
exceeds 3:1. At this time, we recommended that you select the electrical appliances with
lower power rate.
(3) When the output is overload, over-current or short circuit, the product will turn off the
corresponding output, and then it will automatically start twice (at an interval of 20s). If
there is still an overload, over-current or short circuit alarm, the output will be locked, and
it needs to be manually troubleshooting and then restart. If the output stops repeatedly
after restart, please stop using it immediately (only after troubleshooting) or contact the
seller or maintenance agent for help.
(4) When the battery power is discharged to 0%, the DC and AC output will automatically
turn off. Only when the battery power is charged to more than 5%, the DC and AC output
can be turned on, which is to protect the battery and enhance its cycle life.
(5) This machine supports charging and discharging simultaneously.
10. Estimation of operating time
2000Wh × DOD × η ÷ (load W) = charging time（unit：h）
Note：DOD is the battery discharge depth，η is the local inverter efficiency,
DOD=90%,η=88%。
