The Epever MPPT Tracer AN series is an advanced solar charge controller MPPT algorithm-based. High-Quality Solar Technologies (HQST) offers one of the best PWM models of the market. Electronic protection against overload, short-circuit, reverse polarity. In addition to the meter, you also get a remote temperature sensor designed specifically for the dual controller. You can check the battery voltage, the amount of power coming from the solar panels, and the status of external loads. An algorithm in the controller constantly checks the maximum amount of power the solar array is delivering. This charges the batteries faster and maintains good performance on cloudy days. Preprogrammed parameters according to battery type. The LCD screen offers the end-user a complete visualization of the system status and makes it easy to set the working mode of the battery discharge and load feeding process. If the charge controller has that feature, it will likely come with an external temperature sensor, or you’ll need to buy one separately. Thus, the number of solar panels that can you connect to your controller depends on your array open-circuit and operating voltages, and the maximum operating current. Another issue is that the charge controller does not come with an external battery temperature sensor, and there doesn’t seem to be one available separately on Amazon or the manufacturer website. Many care about the aesthetics of the controller once it is installed. The only complaint from customers is that the contacts are a bit too close. Instead of setting up a separate solar panel for each battery, you can charge both from a single panel.

The controller then adjusts the voltage to maximize the amount of power going into the batteries. The decently sized display shows you real-time information.

The EPEVER dual battery solar charge controller allows you to charge both batteries using the same connection from your solar panel or panels. It is one of the most versatile PWM solar charge controllers you’ll find. How To Size a Backup Solar Generator For Your Home. The controller is good enough for most residential solar systems. It does this in several ways: 1. You can also configure various parameters and switch between modes. All batteries require a different type of charging process. But it still provides the same solid protection to your batteries from overcharging, overheating and short-circuiting. It will help you choose the best one for your needs and budget. The Victron SmartSolar MPPT 100/20 model is made by the well-known high-quality manufacturer based in the Netherlands, Victron Energy. So it displays only basic data. One key to zero clearing PV energy function, Error LED indicator tell you what's wrong with your system, Isolated RS485 with 5VDC/200mA to protect output for no power devices with MODBUS protocol, To monitor or set the parameters by using the phone Apps or PC software, Compatible with 12V and 24V systems. The OOYCYOO solar charge controller uses MPPT charge management technology to draw the maximum power from your solar array at all times.

The charger is upgradable by purchasing Victron add-ons such as the battery monitor BMV-700 series, which provides status information like voltage, current, watts and more. There is no risk of overcharging or overheating, which can degrade your battery. The dual solar charge controller comes with a remote meter that lets you monitor the state of each battery and the amount of power they are receiving. A charge controller can prevent this by automatically turning off the load when the battery drops to a certain voltage.

The display can be difficult to read in some lighting conditions. But you can still find PWM controllers that are compatible with lithium batteries and MPPT controllers that are ideal for lead-acid batteries only. You can track basic information on the small LCD display, including battery level, voltage, and temperature. This ensures your system is at peak performance all the time. You can select from one of three types of batteries: sealed, flooded and gel.
