How to adjust the 12 v solar street lamps controller

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, we should be how to distinguish them is white? For this, specially consulted shandong beams of the solar street lamps factory technician. Let's share some simple about solar street light controller identification method: 1. High pressure ( HVD) Disconnect and restore functions: the controller should be disconnected and restore the function of the input high voltage connection. 2. Under voltage ( LVG) Alarm and restore function: when the battery voltage drop to under-voltage alarm point, the controller should be automatically send out sound and light alarm signal. 3. Low voltage ( LVD) Disconnect and restore function: this function can prevent the excessive battery discharge. By the load connected to the relay or electronic switch, 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 manual to reconnect. 4. Short circuit protection function: (1) to prevent any load circuit protection; (2) circuit protection, prevent charging controller internal short circuit; (3) to prevent the battery reverse discharge through the solar modules in the night; (4) to prevent load, solar energy battery components or the battery polarity inversion circuit protection; (5) prevent many minefield breakdown due to lightning. 5. Temperature compensation function: when the battery temperature below 25 ℃, the battery need higher charge voltage to complete charging process. Instead, higher than the temperature of the battery charge need low voltage.
