Hight Protection Solar Panel Power Controller , Waterproof Charge
Controller
solar energy controller SR-HP2420
1. 12V/ 24V system voltages are automatically recognized.
2. An upgraded 3-stage PWM charging algorithm is adopted.
Application of an equalizing charging to the battery periodically
or when over discharged, can effectively prevent the
battery from non-equalization and sulfuration, thus extending the
battery's service life.
3. With temperature compensation employed, charging parameters can
be automatically adjusted.
4. A wide range of load working modes facilitate the product's
application to different types of load.
5. The product provides overcharge, over-discharge, overload
protection, as well as short-circuit protection.
6. By virtue of an advanced load starting method, large-capacitance
loads can be started smoothly.
7. The product provides a dot matrix graphic LCD screen and a
human-machine interface with a key.
8. The user-friendly design of browser and dynamic interfaces
ensure convenient and intuitive operations.
9. Boasting an industrial grade design, the product can function
well in various tough conditions.
10. TVS lighting protection is adopted.

Why choose solar panel?
Reliability
When you install solar panels on your home with a battery charger,
then your flow of electricity becomes more reliable. If an outage
occurs due to a natural disaster or a human accident that knocks
out power lines, then you have energy to power your refrigerator,
air conditioning and other important appliances and electronics.
This offsets the difficulty of getting energy on cloudy days.
Low Maintenance
Solar panels have almost no moving parts which makes them easier to
maintain. As a homeowner, you would only need to clean the panels
on a regular basis and this activity does not require any special
training or cleaners. If the panels are ever damaged by other
parties or the weather, repairs are usually quick and inexpensive.
Technological Development
As a user of solar panels, you would be contributing to further
development of solar panels. While this may not directly impact
your pocket book, it does mean you would be making home energy more
efficient for your children and other generations to come. This
development is often why local and national governments will offer
rebates for home owners with solar panels.
