control mppt 150/35 and other, rule delay 120s

Hello,

i have a small problem with the charge controllers, which i control with my own software. it sometimes takes more than 120s for the charge controller to increase the power after i have sent it the corresponding values. sometimes it goes very quickly and sometimes only slowly until it has regulated up to full power again.

Is there anything I can do to make this go faster?

the purpose of the whole thing is that i would like to determine how high the current maximum output of my system is, even if the battery is already full, but enough current can flow into the battery (soc<98%) or is consumed is used in order to be able to operate one of the many charge controllers at full power.

for this purpose, all led controllers are set to a voltage that is correspondingly lower than the current system voltage and one to the maximum charging voltage, or a slightly higher voltage, so that this one controller can increase its performance to 100%.

Unfortunately, I had to find out that the rule delay goes from a few seconds to over 120s. i was able to easily eliminate the rule delay caused by my program. but unfortunately i could not influence the time from which the mppt charge controller has the new values until it reaches its maximum output.

my software is set up in such a way that it transfers changed values (or values that are marked accordingly) immediately and transfers all values for the controller again about every 35 s +/- 3 s to avoid a timeout.

is there any register i can set to shorten this time?

would it maybe help to shorten the pauses between sending the values?

goodbye
