What to Look for When Buying MPPT Charge Controllers
Are you wondering how to select solar charge controller? Here are a few things worth considering when picking one for yourself:
Voltage Rating
It is critical to check the voltage rating of your MPPT solar charge controller. Different battery setups and solar panels utilize distinct current voltages. These mainly include 24-V and 12-V solar panel setups that aren’t compatible with each other. If possible, get a charge controller that can handle both 12 volt and 24 volt systems.
Safety
Your safety must be a priority. It is best to seek professional services if you are uncertain about handling the technical details related to your MPPT charge controller.
Maximum Current
You must inspect the maximum current rating if you wish to know more about your solar MPPT charge controller’s performance. This will also help determine if it could handle high-load appliances.
While basic charge controller versions merely support 10 to 20 amps of maximum current, more excellent versions are designed to handle 30 amps or even 40 amps of electricity without any problems.
Manufacturer’s Warranty
When shopping for the right MPPT charge controller, check if a product warranty supports it. A product warranty can serve as your investment protection if something goes wrong with the product you purchased.
A product backed up by at least a 1-year warranty or more is regarded as a great deal. Be sure to carefully read the terms and conditions of the product warranty so you could avoid violating any of them.
Price
You should know how much you can spend on a charge controller. This way, it will be easier to narrow down your options.
Additional Features
Many solar charge controllers come with attributes that make usage more convenient and enhance safety. For example, you can find solar products with LED screens, remote control systems, and protection against overloads, short circuits, or electric arcs.
What Size MPPT Charge Controller Do I Need
To determine the size of the charge controller you need, you’ll need to take the number of panels and multiply it by watts to obtain the total watts of the solar array.
After getting the total watts, divide it by the battery bank’s voltage to obtain the amps. From there, add 25% to make allowance for cold temperatures. And, the final step would be to round it up.
For instance: 2 x 140 watt solar panels in series = 280W; divide this by 12 VDC (battery bank) and add 25% = 29.18 amps.
This means that you need to pick a 30-amp 12 VDC charger. Please note that solar charge controllers are sized and graded by the solar panel’s system voltage and array current.
Which is Better, MPPT or PWM
MPPT controllers are specifically engineered using state-of-the-art technology. This is the reason why they are pretty famous for countless consumers these days. They offer users a stellar combination of the most efficient features of a PWM controller, but are designed to be more functional.
On the other hand, a PWM controller provides users with an uncomplicated user experience mixed with a time-tested and proven design. It functions by transferring to the battery a streak of short charging pulses. From there, the charge controller will continually examine the charging condition of the battery and automatically modify the pulse signals to match it.
How Many Watts Can a 40 Amp MPPT Charge Controller Handle
It is best to refer to a charge controller manual to validate the actual watts that a specific charge controller model can handle. Remember that the total number of watts should be highly considered because exceeding it could damage your charge controller.
