FAQs

How do I choose the right charge controller for my solar system? 

To choose the right charge controller, consider your system's voltage, maximum current requirements, battery type, and future expansion plans. Typically, match the controller's amperage rating to your solar panel output and battery bank size for optimal performance.

Can I use a battery charge controller with lithium-ion batteries? 

Yes, you can use a battery charge controller with lithium-ion batteries, as many modern charge controllers support them. However, choose a controller for lithium battery chemistry with the appropriate voltage settings and charging profiles. 

What voltage systems do your charge controllers support? 

At Build The Power, we have charge controllers for 12V, 24V and 48V systems. You’ll definitely find the perfect option for your needs, whether it's for residential, RV, marine, or off-grid power applications. 

How long do battery charge controllers typically last? 

A quality charge controller can last 5 - 10 years with proper usage and maintenance. However, environmental conditions, usage, and even product grade can impact its lifespan. This is why we recommend buying controllers with extended warranties to protect you from unplanned expenses. At Build The Power, all our charge controllers come with an extended warranty period.
