Product Details

eMPPT3024Z Solar Charge Controller with

Maximum Power Point Tracking

Functions

1 Maximum Power Point Tracking technology

The controller uses Buck conversion circuit and MCU technology to track the maximum power point to implement the maximum output power of solar panels in different illumination intensity and temperature. The MPPT algorithm increases efficiency of your PV system and decreases the quantity of solar panels.

2 Multi-stage Charge Control

The starting charging voltage of battery is different, the controller will use the different charging strategies to finalize the charging process. When starting charging voltage of battery is lower than 12.4V (for 12V battery), battery will go through three stages as Bulk, Absorption and Float charging. When starting charging voltage of battery is higher than 12.4V (for 12V battery), battery will go through two stages as Bulk and Float charging.

Bulk Charge, Absorption Charge, Float Charge.

Solar panels configuration

eMPPT series controller can be connected with mono solar panels and also thin film solar panels. When making the system, make sure the open circuit voltage of solar panels array is not higher than the maximum voltage permitted by the controller. Chart one is to introduce the models of mono solar panels and thin film panels and their parameters. Chart 2 is the configuration solution for 12V, 24V and 48V system for solar panels;
