Pure Sine Wave Inverter 300W

Using Environment
In order to get best using results, please put the inverter on flat surface, such as the ground, car floor or other solid surface which can easily fix the inverter's power cord.
The working place should meet following criteria:
Keep dry, should not let the inverter contact the water or other liquids, keep the inverter away from moisture or water.
Cool environment, keep the temperature between 0 Celsius degrees (no condensation) to 50 Celsius degrees. Do not put the inverter next to heat vents or other heat vehicles. Try to keep the inverter not be shined directly by the sunshine.
Ventilation. No objects block around and keep free flow of the air. Do not put anything on the inverter when it's working.
Safety. Do not use the inverter around combustible material or flammable gas.
Batteries can not only provide DC from 10V to 15V (under 12V system), but also have enough current for loads. The power supply should be a fully charged lead-acid battery with good quality and capacity or lithium battery with sufficient discharge current. The rough estimate of the current of one load is dividing the power of the load by 10 (12 systems).
