GRANKIA CMR6048 best 12v 24v 48v 60 amp mppt charger for boat is a DC-DC converter that maximizes the efficiency of a solar system.
CMR6048 best 60 amp mppt charger converts the voltage coming out of the panel to match what the battery needs. Utilizing an additional 20-30% of power out of your system becomes more advantageous as the size of your system grows. For this reason, MPPT charge controllers are often best used on large systems and may not be worth it on smaller, simpler setups.

Solar Controller FAQ
| Q: I want to size or oversize my PV array, how can I do this? |
| A: In short, the solar charge controller you choose must be able to support the power requirements of your loads, your battery voltage, and your PV current and voltage inputs. Additionally, you will need to consider whether you need a controller with low voltage disconnect, lighting control, or other features or certifications. Your climate, choice of modules, and price will also determine whether you choose a PWM or an MPPT controller. A good solar distributor will be able to help you size and configure your modules, batteries, and controllers for an optimum system. |
| Q: Can the output of the MPPT be used as a power supply, thus without batteries? |
| A: The answer is: it depends on the type of load. During low current situations the MPPT control bandwidth is too small to be able to maintain a stable voltage. The result is that loads that need to see a stable voltage before they can activate or loads that require a certain “under voltage” to active will not be able to run. Loads where under voltage does not apply, like light globes, can be operated without any problems. |
| Q: What is load control and low voltage disconnect (LVD)? |
| A: A feature that protects batteries from over-discharging by disconnecting electrical loads when a battery’s voltage drops below a certain setpoint. Load control and low voltage disconnect are two terms that mean the same thing. |
