Different power stations have various conditions that prompt the fan to start running of fan operation, for RIVER series, you can set that manually in the app, or set it to always be on.

For DELTA (1300), the fan will turn on when the internal temperature is greater than 45°C.

Yes, but please note:

– The transfer switch should be connected to the power station’s AC output port;
– You should disconnect the circuits from the grid before they are supported by the power station;
– The total power consumption of the circuits should not exceed the output power rating;
– The output will not be grounded if the power station is not connected to the grid.

Yes, we recommend connecting 2 same units in series at most. Furthermore, please also note:

1. The slave unit must be fully charged before being connected.
2. Must not charge the main unit when the slave is connected.

1. If DELTA is charging from an AC outlet, confirm that the AC switch is turned on. The same goes for DC outlets.
2. If the AC or DC switch is turned on and it still cannot be charged, confirm whether the output power of DELTA meets the rated wattage of the electrical appliance.
3. When the power from a DC source or car charger is less than 1 watt, the charging power will not be displayed, but the unit is charging. Try charging from another power source to see if the charging power is displayed.
4. When the screen displays an overload alarm, the charging power is too high. Shut down and allow the unit to cool down for 30 minutes, or try using a low-power device before charging again. If there is still an overload prompt, take a photo or video of the issue and contact [email protected]
5. The AC switch will automatically turn off after 12 hours if the power of the electrical appliance is less than 10W because the power detection is equivalent to zero power output.

The ‘Recharging Time’ icon, the ‘Exclamation Point’ icon, and the ‘Overload’ icon will flash together on the screen.
1. Check whether the input current is too high. Once you have confirmed that is not the problem, restart the machine and charge again.
2. If the overload still occurs, please contact [email protected]

DELTA supports EPS (Emergency Power Supply). When DELTA is plugged into the grid to charge using AC, any load plugged into the DELTA will be directly powered from the grid and not DELTA. If there is a power outage, DELTA automatically switches to its battery supply mode within 30 milliseconds. Any device plugged into the DELTA will have no power for 30 milliseconds, making it unsuitable for desktop computers or data servers which must be reconnected to power within 0 milliseconds (UPS).
UPS is unnecessary for all devices, and we advise testing yourself before using the EPS function. It is recommended that only one device is plugged into DELTA to avoid overloading.

1.In EPS mode, the DELTA uses the by-pass function. The DELTA connects to the grid and receives direct AC charging, and the load device directly uses the AC power from the grid. DELTA acts as a pass-through unit.

2. In EPS mode, when the battery has between 97% and 100% power, the AC input will not charge the battery. When the power is below 97%, the AC input will be used as a by-pass output and also charges the battery.

1. To prolong the battery life, we recommend that you use and store DELTA in an environment of 20°C to 30°C, away from water, heat, and metal objects.
2. For long-term storage, discharge the product down to 30% and then charge it up to 60%. Continue to follow this procedure every 3 months. Units that are not charged and discharged for more than 6 months will no longer be covered under warranty.
3. For safety reasons, please do not store this product in an environment above 45°C or below -10°C over a long period.

Solar charging input: 400W, 10-65V, DC 10A (Max)
Charging Time: 4-8 hours (110W x 4)
