Solar Energy Systems

Portable solar generator: Changhong solar charge controller  specially developed for Changhong solar PV power systems has overcharge & over-discharge protections, short-circuit protection, reverse charging protection and reverse polarity protection, which are applicable for 3KVA~300KVA off-grid solar power station and household electrical facilities in remote area. In addition, solar charge controller can be designed and produced according to specific requirements.

Changhong solar chargers and inverters are newly developed power supply systems based on traditional switching power supply technology. It adopts CPU control circuit and monitor interface to realize the remote signaling, remote control, remote measuring and remote regulating of the rectifier module. Besides, adopting high frequency PFC and phasing resonance technologies greatly improve electrical properties, in particular of input voltage range and overall efficiency.

Electrical Design Feature

1. Adopting soft-start and soft-impact time delay circuit enables rectifier module to have no surge impact on electricity grid.
2. Adopting automatic power factor correction (APEC) not only effectively reduces ripple, cacophony and harmonic wave, but also improves the power factor.
3. Adopting bridge ZVS circuit greatly improves overall efficiency
4. Adopting voltage ¤t dual-loop control circuit ensures its excellent dynamic property.
5. Adopting automatic share current technology ensures the high accuracy of multi-machine paralleling current-sharing.  Adopting intelligent heat dissipation technology enables fan to start automatically when the temperature inside the cabinet is high, otherwise, the power system becomes self-cooling. Battery interface on output terminals has functions of charging current limitation and over-discharge protection.

Changhong solar energy system are widely applicable as AC or DC power supply for 25~29 inches CRT TV sets, 32~42 inches LCD TV sets, portable DVD, notebook PC, digital satellite antenna receiver, speaker, lighting, LED, mobile phone charger and other more household electrical appliances in remote area. In addition,  they are specially adapted for communication, irrigation, geological exploration, mining and other industrial electrical appliances for small factories in remote area lack of electricity.
