12V or 230V Appliances
If using 12V appliances these can connect directly to the 12V battery or the Load Terminal on a Solar Charge Controller taking into account the current used by the appliance is less than the Amp rating of the controller.
If you would like to run household appliances (230 Volts) then an inverter is connected to the 12V battery which then converts to 230V. Inverters are rated in Watts so a question of sizing an appropriate unit which is rated at least a third higher than the appliance. For example appliance rated at 1500W use a 2000W Inverter.
If running an appliance with a motor (for example power tools) the initial power demand can be three or even four times the appliance rating so will need an appropriate Inverter to cope with initial demand.
If your using any appliance with sensitive electronics or with a timer mechanism then a Pure Sine Wave Inverter should be used to enable the appliance to function correctly. Inverters
