Frequently Asked Questions
1. How should I wire my panels with an MPPT charge controller?
1. How should I wire my panels with an MPPT charge controller?
The panels can be wired either in series or parallel or a combination of series/parallel.
2. What is the max wattage input on the Rover 40?
2. What is the max wattage input on the Rover 40?
The Renogy Rover 40A MPPT Solar Charge Controller can accept input of up to 520W for a 12V system, and up to 1040W for a 24V system.
3. Does the Rover 40A MPPT charge controller have a built-in 40A fuse for the rated 40A load output?
3. Does the Rover 40A MPPT charge controller have a built-in 40A fuse for the rated 40A load output?
No. Please always add a fuse between the charge controller and batteries. To determine the fuse size, you can match it to the amperage rating of the charge controller. If you have one of our 40A charge controllers, we recommend using a 40A ANL fuse.
4. What are the advantages of Renogy MPPT technology?
4. What are the advantages of Renogy MPPT technology?
Renogy Rover Series solar charge controllers use Power Catcher MPPT algorithm to always ensure the charge controller converts most energy by locking to the most optimal maximum power point.
5. How many watts can Renogy Rover 40 amp charge controller handle?
5. How many watts can Renogy Rover 40 amp charge controller handle?
The Rover MPPT charge controller can work with standard off-grid 12/24V solar panels with high voltage or multiple panels with voltage up to 100V. And the maximum combined input solar power is 520W for a 12V battery system or 1040W for a 24V system. In particular, this controller will significantly increase the efficiency of a solar system where the solar panel voltage is much higher than the battery voltage.
6. What is a Solar Charge Controller and what is MPPT?
6. What is a Solar Charge Controller and what is MPPT?
The Charge Controller takes the power made by the solar panels and transform the ‘solar panel power’ into a form of power that the batteries can use. MPPT stands for Maximum Power Point Tracking, and it relates to the solar cell itself. Each solar cell has a point at which the current (I) and voltage (V) output from the cell result in the maximum power output of the cell. MPPT ensures that you get the most power possible from your solar panels at any point in time. It is particularly effective during low light level conditions.
