STAND ALONE configuration:
The "Stand Alone" systems are used to carry electrical energy where the national electricity grid does not reach: country houses, chalets , cottages , gardens, boat or RV.
Solar energy and wind energy is captured by solar panels and wind turbines, and , through a charge controller , is transferred to the battery where it is collected and stored for use upon request. Finally , an inverter "stand alone" converts the DC 12 -24V stored in the batteries into alternating current 110/220V for appliances .
With this system you catch and accumulates energy when nature gives us the ( sun and wind) for use when needed ( even at night or in the absence of wind). More battery bring you more energy accumulates.
