Highlights: hybrid solar street light can switch freely between DC AND AC.

THE CLIENT FROM Philippines WANT TO REPLACE THEIR CURRENT high pressure sodium lamp with solar lamp to save some electricity.

But due to local fluctuate weather, the client still want to keep utility power as backup.

So we recommend our hybrid solar street light which can switch freely between DC AND AC. The client can choose AC or DC as priority as they need.

For example, if chosen DC power as priority, the lights will worked with DC power when battery voltage above the settled warning line, but when come to long continue rainy days, the battery voltage lower to the limited level, the lamp will switch to utility power and continue deliver brightness. So that ensure the lamp will works all year round no matter what kind of weather condition.

Vice versa, if chosen utility power as priority, the lights will worked with utility power normally, when come to blackout, the lamp will switch to DC power and continue to work. After power on, the lamp will switch back to utility power again. So that ensure the lamp can also work under emergency situation.
