RECOMMENDED SOLAR PANEL WATTAGE PER CHARGE CONTROLLER

If you're looking to set up a solar system, then one thing you must take into account is the wattage of your solar panels. For optimum performance, it's important to have the right size solar panels matched with the charge controller you're using. If you're planning to use a 10A, 20A, 30A, or 40A Newpowa Charge Controller, then this guide is for you.

To start, let’s cover the Max PV Inputs for our 10A Charge Controllers. If you’re just getting into solar, then these are the perfect choice for a small-scale system.

Now, let’s talk about our lineup of 20A Charge Controllers as well as their Max PV Inputs. What’s great about these is that they have a higher PV allowance, making them the perfect addition for any small to mid-range solar systems.

Now, if you want something to accommodate your mid to large-range solar setup, a 30A Charge Controller would be a good place to start as they are scaled up in terms of wattage allowance.

Lastly, if you plan to run a large system, our Frigate 40A Charge Controller would work well in this scenario as the Max PV Input is higher than all the previous controllers mentioned in this article.

Remember, choosing the correct charge controller for your solar setup is also based on whether you’re wiring in series or parallel. When wiring in series you will double your panels’ voltage and keep the same amperage. But if you wire in parallel, you’ll keep the same voltage while doubling your amperage.

Before making a decision, it’s always important to ensure that your charge controller can handle not only your solar panels’ overall wattage but their respective voltage and amperage to avoid any damage or underperformance.

We hope this guide has helped you understand the recommended solar panel wattage per charge controller and enabled you to choose the appropriate controller size for your needs.
