AC packages are perfect to power conventional home appliances that use power from a normal socket. An AC package usually consists of a number of FLEXI solar panels, a battery, a solar MPPT charger and a solar inverter. The FLEXI solar panel charges the battery through the MPPT (or PWM) solar battery charger. And an inverter converts the power from the battery so you can use it like a normal socket like you have at home!
An AC solar system is in fact a DC package with a solar inverter so you can power normal home appliances.
