Street lamp bracket1

In the face of wide variety of solar street light fittings products on the market, as a small white how do we discern the stand or fall of them? For this small make up a specialized consulting the shandong beams of the solar street lamps factory technician, we here simply to share some about too

full of beautiful things in eyes in facing the market of solar street light fittings, how can we distinguish between them for the small white? For this purpose, the editor's specially consulted our shandong the beam of the solar street lamps factory technician, and briefly share some identification method of solar street lamps controller: 1. High pressure ( HVDC) Disconnect and restore functions: the controller should have input voltage disconnect and restore function. 2. Under voltage ( LVG) Alarm and restore function: when the battery voltage drop to under-voltage alarm point, the controller automatically send out sound and light alarm signal. 3. Low voltage ( LVD) Disconnect and restore function: this function can prevent the battery discharge. Through the relay or electronic switch connected load, can be at a given point of low voltage automatic cut off the load. When the voltage to the safe operation range, load automatically reconnect or need to manually reconnect. 4. Protection function: ( 1) To prevent any load short circuit protection; ( 2) Circuit protection, prevent charging controller internal short circuit; ( 3) Protect the storage battery at night from solar modules back discharge protection; ( 4) Circuit protection, prevent the load, the solar cell module or reverse polarity of battery connection; (5) to prevent more minefields lightning strike breakdown protection. 5. Temperature compensation function: when the battery temperature below 25 ℃, the battery need higher charge voltage to complete charging process. Higher than the temperature of the battery, by contrast, need low charging voltage.
