To determine the maximum PV array power suitable for your EN43510 MPPT Solar Controller, you should consider the rated charge current of the controller, the maximum PV array power recommended, and the maximum PV array power allowed. Here are the key considerations and limitations when selecting the PV array for this controller:



1. **Rated Charge Current:** The EN43510 controller has a rated charge current of 10A.

2. **Maximum PV Array Power Recommended:** The recommended maximum PV array power for the EN43510 controller is 150W for a 12V system and 300W for a 24V system.

3. **Maximum PV Array Power Allowed:** The maximum PV array power allowed, including overdrive, is 180W for a 12V system and 360W for a 24V system.



It is important to ensure that the power of your PV array does not exceed the rated charging power of the controller to avoid potential damage. Exceeding the maximum power limits can lead to reduced efficiency, prolonged charging times, and potential damage to the controller.



When configuring your PV array for the EN43510 controller, ensure that the open circuit voltage of the PV array does not exceed 92V at 25°C environment temperature. Additionally, consider the environmental conditions and the specific requirements of your system to optimize performance and ensure safe operation.



Refer to the table provided in the manual for a detailed breakdown of the maximum PV array power recommendations and limitations for the EN43510 controller.
