Option 3. 2 v solar street light should pay attention to what issues?

- -

as the government to the beautiful countryside construction work further, solar street lamp is more and more widely applied in the new rural construction. Beautiful countryside construction, the outdoor road lighting will choose solar street lights will be a fresh air to the new rural construction.

there are on the market at present. V and V of these two kinds of system voltage of solar street light. V system, compared. V solar street light prices cheaper, but quality is also more & other; Good and evil people mixed up & throughout; So we in the choose and buy. V must pay attention to the following solar street lamps, avoid cheated by some undesirable businessman.

a,. The choice of V batteries, lithium-ion batteries.

in the market. V solar lithium batteries are mainly auto pointed out down the lithium iron phosphate batteries and the flat head of out products for lithium iron phosphate batteries. Fewer pointed lithium iron phosphate batteries cycle, short service life, while using this kind of batteries made of cheap solar street lamps, but this. V solar street light has many disadvantages. And flat batteries, lithium iron phosphate cycles of time, so use this batteries. V longer solar street lamps, profits can be used to years.

(2). The choice of V solar street lamps controller.

. V can use flat solar controller and solar street lamps booster solar controller. If collocation pressure controller, solar street lamp lights biggest can reach W, the controller is suitable for solar street lamps used under meters to m. If the height is higher than to want better lights, solar street lamps lighting power is bigger, so can only choose booster solar controller, it can make the light power reached the extent to which you want. But the price of the booster solar controller than flat solar controller is a times more than price.

3, regional temperature due to the lithium iron phosphate batteries are not resistant to low temperature, the temperature below zero degrees will happen without lights, so the south region only.

the combination of the above two considerations, we can draw the conclusion:. V solar street lamps use flat lithium iron phosphate batteries and booster solar controller, a light effect is good, not only on the service life is more than the V solar street lamp, and on the overall price than V offers some solar street lamps, but if the price is too cheap, we will be careful solar lithium batteries could be eliminated down the lithium iron phosphate batteries.
