1200W household solar power generators

Detailed introduction to 1200W household solar power generators:

Solar system by solar cells, solar controller, battery (group). As output power to communicate or 110V, still need one 220V configuration inverter. Each part of the role for:
(a) solar panels, solar panels are the core part of solar power system, is the highest value in solar power systems. Its function is to convert the sun's radiation ability to battery power, or in storage, or promote work load. The quality and cost of solar panels to directly determine the quality and cost of the entire system.
(2) solar controller: the solar controller is control of the whole system, and the working state of battery charging protection, has had discharge protection. In place of large temperature difference and qualified controller should also have the function of temperature compensation. Additional functions such as optical switch, control switch should be controller can options.
(3) battery: general for lead-acid batteries, small miniature system, usable also ni-mh battery, the battery or nickel cadmium lithium batteries. Its function is in a light emitted when solar panels of energy storage, the need to release.
(4) inverter, on many occasions, need to offer 220VAC, 110VAC communication power supply. Due to the solar direct output is generally 48VDC, 12VDC, 24VDC. For 220VAC appliances to provide power, solar power system needs to be issued by a DC can convert communication power, so need to use DC - AC inverter. On some occasions, need to use a variety of voltage when the load, and can also be used with DC - DC inverter, as will transform electrical energy 24VDC 5VDC power (note, not easy buck).
