Renogy Rover 100 Amp MPPT Solar Charge Controller
Introducing the new 100A Rover MPPT Charge Controller, the largest Rover controller that Renogy has to offer. Capable of supporting up to 1300 watts on 12 volts, 2600 watts on 24 volts, 3900 watts on 36V and 5200 watts on 48V. This off-grid controller was designed for large-scale projects, both mobile and stationary. For even more power, users can utilize a unique feature limited to this Rover and connect two 100A Rover controllers in parallel for a total of 200 amps! This smart charge controller can also conveniently self-diagnose itself in the event of an error and can be remotely controlled through the DC Home app using the Renogy BT-1 Bluetooth Module. By pairing the Rover with the new BT-1 and the DC Home app through Bluetooth, users can easily monitor and adjust their solar system straight from their phones.
The Rover automatically detects 12V, 24V, 36V and 48V DC system voltages, and is compatible with a variety of Deep Cycle battery options, including AGM, Sealed, Gel, Flooded and Lithium. Renogy's innovative MPPT technology provides high tracking efficiency up to 99 percent and peak conversion efficiency of 98 percent. It offers electronic protection against reverse polarity, overcharging, over-discharging, overload, short-circuiting, and reverse current. The LCD screen and multiple LED indicators display system operation information, customizable parameters, and error codes. The Rover features both RS232 and RS485 ports. RS232 allows the Rover to communicate with the BT-1 Bluetooth module, which can pair with the DC Home smartphone app.
With an MPPT controller, rather than regulating voltage, it actually behaves as a DC voltage converter. By doing this it essentially acts as a power regulator. This allows the controller to accept any input of power (within its voltage/current range) and convert it to the appropriate voltage for the battery bank. DC voltage converters typically have an efficiency above 90%, depending on the level at which the converter is run. Depending on the input, the efficiency can actually range from 90 to 99 percent. The output current of an MPPT controller will always produce more current flow to the battery than a PWM controller will. Since we know on average that the PWM controllers have an average efficiency of around 79 percent (max) and MPPT has an average efficiency of 94 percent, an MPPT will produce a current of about 1.2 that of the array current or 20 percent higher than the array. it maintains a higher efficiency and boosts the array current to more quickly charge the battery rather than wasting energy as heat. In addition, MPPT controller typically supports a higher voltage input which allows for the wiring of the panels in series. This can be advantageous in systems with long panel to-controller wire runs as it will overcome voltage losses in the wiring. MPPT controllers attempt to ensure maximum power conversion and for that reason are typically used in critical power applications and are essential for bigger systems. 500W solar power systems and more should use an MPPT charge controller.
Renogy’s Maximum Power Point Tracking (MPPT) controllers maximize the production output of your solar system. Rather than dissipating excess energy as heat, an MPPT controller monitors and regulates your system’s current. While this typically means a lower voltage yield, your overall output will increase as a result of current management and you can expect efficiency ratings of 90 percent or higher.
