FAQ
How many watts can a Power Queen 30A solar charge controller handle?
The Power Queen 12V/24V 30A MPPT Solar Charge Controller is designed to function with standard off-grid 12V or 24V solar panels that can handle high voltage or multiple panels with a combined voltage of up to 100V. It supports a maximum input solar power of 450W for a 12V battery system and 900W for a 24V system. The default configuration of the Power Queen 12V/24V 30 Amp MPPT Solar Charge Controller is set for a 12V LiFePO4 battery. However, it can also be adjusted to support 24V LiFePO4 batteries, as well as sealed and gel lead-acid batteries, by modifying the parameters.
Is an MPPT too big?
There is a practical limit to the size of the solar array. If the array is too large, excess power will be wasted because the charge controller continuously limits the output to protect the system. It is generally recommended to size the solar array to 110%-125% of the charge controller's maximum rating to optimize performance without overloading the system.
Does an MPPT make a battery overcharge?
Power Queen solar charge controllers employ maximum power point tracking (MPPT) technology to optimize solar energy production and regulate the battery charging voltage, ensuring efficient charging while preventing overcharging.
What does an MPPT do when the battery is charged to full?
When the battery voltage indicates that the battery is fully charged, the charger will disconnect and stop drawing power from the MPPT controller. At this point, the battery charger effectively presents a high impedance to the MPPT controller.
Can I connect an MPPT with an inverter directly?
No. MPPT solar charge controllers are designed to efficiently direct current into your depleted battery. Connecting an MPPT solar charge controller directly to an inverter is a bad idea. Doing so can potentially damage your solar system, and if no damage occurs, the inverter will receive zero input. Therefore, always avoid connecting MPPT controllers directly to inverters.
Is MPPT better than PWM?
MPPT controllers are often more expensive than PWM controllers. However, they perform more efficiently under certain situations, allowing them to generate more power with the same number of solar modules as a PWM controller.
What size charger controller should I use for a 30 watt solar panel?
Power Queen solar charge controllers keep the current from the panels at a safe level so that it may charge the batteries. A 30A controller is appropriate for a 300 watt solar panel installation.

FAQS
Q:Can I use lead-acid battery charger to charge lithium batteries?
Lithium chargers employ a CV/CC charging technique. This approach maintains a constant current until the battery reaches the target voltage. As the battery approaches maximum capacity, the current gradually decreases. This technique allows for rapid charging while preventing overcharging, making it ideal for lithium-ion batteries.
Normal chargers, on the other hand, rarely use the CV/CC technique. Using a lead-acid battery charger with lithium batteries may result in partial charging or even damage to the lithium cells.
For further information, see the article Can I Charge a LiFePO4 Battery with a Lead Acid Charger?
Q:Is it OK to charge LiFePO4 to 100%?
Yes, Power Queen LiFePO4 batteries may be recharged to 100%. Unlike other lithium battery chemistries, LiFePO4 batteries are engineered to withstand complete charges without severe harm. However, for maximum longevity, it is frequently recommended to keep the battery's SOC between 20% and 80% during normal operation.
Q:Is it OK to leave a LiFePO4 battery on the charger?
Although it is generally safe to leave a LiFePO4 battery on the charger because both the charger and the battery have built-in BMS to prevent overcharging, it is nevertheless advised that you monitor the charging process.
Q:Do Power Queen lithium battery chargers have protection?
Yes. Power Queen LiFePO4 lithium battery chargers have a BMS to protect the battery from overheating, reverse polarity, short circuiting, and overvoltage.
Furthermore, Power Queen LiFePO4 Lithium battery chargers support 0V, allowing you to jump start dead lithium batteries.
Q:What types of battery accessories does Power Queen offer?
Power Queen offers a varied range of battery accessories designed to improve the performance and safety of your battery system. Our assortment includes fuses, fuse holders, battery monitors, marine battery boxes, and battery hold-down systems, among other items.
These accessories work with LiFePO4 and other batteries, ensuring that your system functions smoothly and safely.
Q:Why are battery accessories important?
Battery accessories are crucial for ensuring that your battery system is safe, effective, and long lasting. Proper accessories guarantee that your batteries are securely fitted, correctly charged, and protected from overcurrent or short-circuit circumstances. Fuse and charge controllers are two types of accessories that help govern power flow while also protecting your batteries and other connected devices.
Q:What is the purpose of a battery monitor?
A battery monitor measures the state of charge (SOC), voltage, current, and other important battery statistics. It provides real-time information on the amount of power left in your battery and allows you to check its health. This is especially useful for off-grid systems, RVs, naval stations, and other applications where it is vital not to run out of power suddenly. For further information, see the article "What Is a Battery Monitor and Why Do You Need It?"
Q:What is a fuse holder, and why do I need one?
A fuse holder includes a fuse, which is designed to protect your electrical system from overcurrent conditions that could damage the battery or other components. If a short circuit or overload occurs, the fuse blows, disconnecting power and averting further damage. Power Queen fuse holders are designed to be simple to install while offering safe and reliable battery protection.
Q:Can I use Power Queen accessories with batteries from other brands?
Yes, the majority of our accessories are compatible with LiFePO4, lead acid, and AGM batteries. However, you should always check the specs of each accessory to ensure that it is compatible with the voltage, current, and battery type in your system.
