Most electronic devices within 300W. High-draw appliances such as heaters, coffee makers, microwaves, and similar devices are not recommended.

2) What kind of solar panel should be selected to recharge the unit?
We recommend an 80W-160W solar panel with an optimum operating voltage (Vmp) within 24V. Do not use a solar panel with an open-circuit voltage above 24V. For best performance, pair with our 100W Solar Panel.

3) Why does the unit have an Auto-Sleep Mode?
To help preserve battery power, the unit automatically enters energy-saving sleep mode and shuts down power output after about 2 hours when no devices are connected.

4) What kind of "mini-fridge" or "mini cooler" can I use with the unit?
The AC continuous output of the unit is 300W and the battery capacity is 256Wh. It can power devices within 300W, but runtime depends on the actual wattage and startup demands of the appliance. Please note that compressors may draw significantly more power at startup.

5) Is the unit water/weather resistant?
NO. Do not expose the unit to water or damp environments.
