Our extensive product line features battery charge controllers from renowned brands, including Renogy, Xantrex, and PECRON. Whether you need a compact controller for RVs, marine setups, and other off-grid systems or larger models for homes, cabins, or businesses with multiple solar panels, we have the perfect option(s) for your needs. You can also have a look at branded battery charge controllers by Morningstar.

Types of Solar Charge Controllers We Offer: 

PWM Solar charge regulators

PWM are best if you have a small setup or are budget-conscious. They can handle 10 - 30A current ranges while providing stable charge control with simplicity. Shop the Renogy New Edition Voyager 10A PWM Waterproof Solar Charge Controller for the best value. 

MPPT Solar Controller

These advanced controllers can increase your solar system efficiency by up to 30%. They extract maximum power from your solar panel, even in low sunlight or partial shading. Our customer’s favorite is the Victron BlueSolar MPPT Charge Controller. 

Hybrid battery management system

These systems support multiple battery technologies, including lead-acid and lithium-ion, and provide comprehensive energy storage solutions for complex power setups. Our best pick is the Schneider Electric Conext 4kW 48VDC Inverter/Charger. 

Key Features of our Charge Controllers 

Lighting Fast Efficiency 

Get more power and faster. Our advanced controllers are built with advanced solar technology to ensure every bit of energy is converted and delivered to your batteries—fast! Whether you’re charging for everyday use or storing energy for later, these controllers help minimize energy loss and protect your battery’s lifespan.   

Professional, Industrial-grade Build Quality 

Our charge controllers are built with premium-grade materials and can withstand extreme temperatures, moisture, and dust. Even the most affordable options on our lineup provide exceptional durability and reliable performance.   

Multi-Battery Compatibility  

No matter what battery you’re using – lithium–ion, gel, or lead-acid – our charge controllers are compatible with a wide range of battery types. This versatility means you can easily find and integrate our controllers into your system or scale whenever you need to. 

Smart Monitoring Systems 

Let’s face it – solar systems can feel unpredictable. But not anymore. Most of our controllers have smart monitoring systems that provide real-time data on battery status, charging efficiency, and system performance. With easy-to-read LED displays and notifications, you can easily see how much charge goes through your charge controllers, data log, and battery temperature – all from your phone. 

Advanced Voltage Regulation 

Your batteries are the heart of your system, and you need controllers to regulate them. Our charge controllers feature cutting-edge voltage regulation technology that prevents overcharging or undercharging – just the optimal charge to keep your system functioning at its best and for the longest time.

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.
