MPPT Boost Solar Charge Controller 48V 72V


24V 48V 72V 300W MPPT Boost Solar Charge Controller Boost Step-up Charger Car Battery Charging Voltage Regulator for Vehicles, Home, RV, Golf Cart Applications.

MPPT Boost Function

1. Advanced MPPT maximum power point tracking technology, the maximum tracking efficiency is 98%, which can save the energy of the panel and reduce the cost of the panel.

2. using high-quality components to improve system performance, the maximum conversion efficiency of 97%.

3. Ultra-fast maximum power point tracking speed while ensuring tracking efficiency.

4. The four digital tube of this machine has the functions of real-time display of battery board voltage, charging current, battery voltage, etc., which is convenient for a clear display of charging status. And this product allows customers to freely set battery voltage and charging parameters.

5. the wide PV array maximum power point operating voltage range of 12V-50V.

6. Directly display the design with each parameter, dynamically display the operating data and working status of the device, battery board voltage, charging current, battery voltage, etc.

7. Solar panel power-taking technology, standby power consumption is 0, the system power consumption all comes from the battery board, not working at night.

8. This product supports customers to manually set the battery voltage and charging parameters through buttons. It can be applied to a variety of battery types, such as lithium batteries, iron lithium batteries, nickel-metal hydride batteries, lead-acid batteries, gel batteries, and other various batteries type.

9. with a child lock function to prevent accidental touch buttons caused by charging errors.

Features of the MPPT Boost Controller

1. MPPT high-efficiency charging mode, charging efficiency 97%;

2. Overcharge protection function to effectively protect the battery from overcharging;

3. Anti-reverse protection, battery and battery board have anti-reverse protection;

4. Short circuit protection, with child lock, safe and convenient;

5. Can be applied to a variety of batteries, battery board power, standby power consumption is 0.

Child lock instructions

Open the controller with four screws on the side of the digital display tube. You can see a 2-digit DIP switch, the ON position is the child lock opened, and the 1-2 position is the child lock closed. The factory default is the child lock closed.

Please install the personnel to turn the DIP switch to the ON position after the controller installation and debugging are completed, in case the child lock is turned on, to prevent the charging error caused by accidental touch. If you need to set the next time you can dial back to the 1 2 positions, you can disable the child lock.
