hoffumDevice selection
In terms of device selection, there are currently options that use microcontrollers and comparators, each with its own characteristics and advantages. Corresponding solutions should be selected based on the needs and characteristics of the customer group, and will not be elaborated here.
hoffumSurface treatment
This series of products adopts new electrostatic coating technology, mainly FP professional building material coatings, which can meet the customer's requirements for consistent surface color and environmental coordination. At the same time, the products have high self-cleaning, strong corrosion resistance, aging resistance, and are suitable for any climate environment.
hoffumCharging trickle protection
When the solar panel charges the battery, if the battery continues to charge at high voltage after reaching its peak voltage, it is easy to cause the battery to lose water or lose control; If the battery cannot saturate when charging is stopped. This controller immediately drops voltage by 1V after reaching the peak voltage, and then enters a trickle charging state, ensuring that the battery can remain stable in a full state while avoiding dehydration or loss of control. Similar to cyclic charging of the battery, it not only efficiently protects the battery, but also increases its charging frequency, resulting in a longer service life.
The controller is generally placed inside the lamp post and has functions such as light control, time control, overcharging and discharging protection, and reverse connection protection. More advanced controllers have functions such as adjusting the lighting time throughout the year, half power function, and intelligent charging and discharging function; Batteries are generally placed underground or have specialized battery insulation boxes, which can be valve regulated lead-acid batteries, colloidal batteries, iron aluminum batteries, or lithium batteries.
