Solar controllers are responsible for the modulation of the voltage and current flowing from the PV panels to the batteries. They are an essential part of the solar power system as they help in the effective charging of the batteries and prevent any hazardous events such as fire and explosions that can occur due to battery overcharging.
In this article, we will take a look at a few features that we should keep in mind when buying a solar controller.
1. Solar Charge Controller as a Conversion Unit
If you have an existing inverter at your home, you can convert it to a solar inverter using a charge controller that comes with this ability. It will allow you to make the switch from a conventional inverter to a solar inverter without disturbing any of the existing wirings. So, if you are keen on having a charge controller with that feature set, get a charge controller equipped with the technology.
2. The Technology Lifespan
You need to keep the lifespan of the technology in mind when buying a solar controller. You can choose between a PWM and MPPT charge controller, both of which are good. But, if you can afford to spend a bit more, then it’s advisable to go for an MPPT charge controller as it is more efficient and offers better value for money compared to the PWM charge controllers.
3. Keep the Climate in Mind
Some solar charge controllers are built to withstand hotter climates, while some are made to operate better in colder temperatures. Therefore, while choosing a solar controller, make sure that you pick one that’s appropriate for the weather conditions in your area to get the maximum efficiency.
4. Safety Features
Always buy a solar controller which offers you robust safety features such as overcharge protection and protection against the reverse current from the battery to the PV panels at night. Similarly, look for solar controllers with good MCB protection as it helps prevent short circuits.
5. LCD Display
Having an LCD display helps you keep track of what’s going on with the system as opposed to a solar controller without an inbuilt display. Most modern-age solar charge controllers have digital displays that reflect all the vital information you need to know, so it is best to buy a solar charge controller with this feature.
Luminous has a range of solar charge controllers that are available across a range of budgets and functionality options. Even better, these solar controllers are built from the ground up using the highest quality components to offer superior service lives and low cost of maintenance. If you are looking solar controller that would offer you the best of both worlds in terms of technology, design, and features, don’t forget to check out Luminous’ complete catalogue of solar controllers with modern designs and futuristic feature sets.
However, as a consumer, you should always do thorough research before you buy any product. So, if you are in the market looking to buy a new solar controller or thinking of replacing your old one, the points discussed in this article can help you make an informed decision.
Additionally, always buy products from reputed manufacturers like Luminous instead of locally manufactured ones. While the latter might cost cheaper initially, you can end up spending a lot more in the long run as they have the potential of damaging your expensive battery units and hamper the operations of your entire solar power system.
