You can charge your unit between 0 °C and 45 °C. If the temperature drops below 0°C or exceeds 45 °C during charging it stops the charging process. If the temperature was only slightly above or below the limit and comes back to the allowed range, it automatically continues the charging process. If the temperature drops below 0°C goes above 45°C significantly it will stop charging completely and will not automatically continue charging even if the temperatures go back to the allowed range. In this case set the unit to transport mode, disconnect the charging cable and restart the charging process again.

You can use your unit in ambient temperatures between -20 °C and 60 °C. 
What happens at too high or too low temperatures with my Instagrid ONE unit?
Instagrid ONE shows a yellow blinking light and stays off when its inner temperature is below -20 °C or above 60 °C at the moment when you try to turn it on. If the unit heats up and exceeds 60°C significantly during use it turns off and shows a yellow blinking light. Turn the unit off and reduce the load or move the unit to a suitable temperature environment to reset the alarm. The same applies if the temperature drops to below -20 °C during use, even though this is very unlikely as the unit generates enough heat to permanently stay above -20 °C during continues use.

It takes roughly 1 hour until the unit warmed up enough at room temperature to start the charging process.

Instagrid ONE needs a stable AC voltage source that delivers between 120 V and 240 V AC and minimum 4 A of current. This results in a power demand of 500 W at 120 V and 950 W at 230 V. If your power source fulfils these requirements, you can use it to charge your Instagrid ONE.
