ipanda x-plorer mppt input voltage/tracking issue
I have a ipanda x-plorer mppt 60A. I notice that it has a input/tracking voltage issue.
I have (2) 24v 320watt panels in series giving me around 70volts on my input and i am charging a 24v SLA battery.
In full sun my input keeps on fluctuating between 50 to 60+ voltage at a fast pace and sometimes it drops to as low as 28volts and stays there for a very longtime before it goes back to fluctuating between 50 to 60+ voltage in full sun.
Is there a way to solve this issue by updating/flashing the firmware of the controller. If yes could you send me the file to update it or what else can i do?
I await your response anxiously. I really love this controller but the voltage issue is giving me a hard time . I am losing out on a lot of wattage most of the times due to the fact that the input voltage is not steady and keeps on running up on down even thou i am getting a steady full sunshine with no shading effect.
If i put a big 100v 15000uf Capacitor on the input would that solve the voltage sagging issue?it appears to have a tracking issue within the firmware.
