5 W Solar Panel Charge Controller

5 W Charge Controller5 W Charge Controller.

The module comes with a built-in 3-step microcontroller. This ensures proper safe and precise charging.

The controller regulates the output voltage from the solar panel. It also prevents battery damage by overcharging.

The chargers have a status light.

The light indicates the mode of operation of the charger. As well as the condition of the battery that we connect to the charger.

The charger will check and maintain the battery at full charge.

How does the 5 w solar panel work? 

The 5 w solar battery charger is ideal to maintain 12-volt batteries.

It will keep your battery in perfect condition. Your battery will be healthy and ready to use for the whole duration of winter.

You will not experience any problems.

When you store your vehicle for a long time you can do the following. You can expose your solar battery maintainer to a good source of sunlight. Mount it to a sunny surface and your battery will remain charged for the year. 

Even while you keep the vehicle indoors.

Advantages

  • The module is spark-proof and it comes with reverse polarity protection.

  • This comes as a DIY installation that is simple and easy to do.

  • The temperature compensation sensor maintains safe operation within a specific temperature threshold.
  • This panel is a good option for outdoor installations, because it is waterproof.

  • The 5 w solar panel comes with good construction.

  • They protect the electronics very well. The cables are of a good quality and the insulation is of high standard.
  • The corner fasteners for permanent installation are a welcome feature.
  • Even in the winter when we do not get much sunshine the solar module still works well. It is keeping the system charged up.

  • The surface is smooth and flat and a breeze to keep clean.

Disadvantage

Someone suggests that the manufacturer includes some sort of mounting brackets. This is to  mount the 5 w solar panel to glass.

Suction cups to mount on to a vehicle’s window, when maintaining the battery, can be a handy addition.

To mention

  • Do not operate the charger where there is a restriction in ventilation. This is to allow for enough airflow to cut and dissipate heat and to diffuse gasses. Batteries emit gasses and the charge controller generates heat.

  • Attempts to disassemble or to do internal repairs will void the warranty.

  • Be sure to locate all power cords at a safe place out of the way.

  • The 5 w solar panel works well to maintain a battery, but not strong enough to charge a drained battery. 

Warranty

The warranty from Deltran is good for a period of up to 10 years.

In a conclusion


The 5 w solar panel with built in controller is a great product for the money spent.

This can be one of your better purchases.
