I have 3 modules, each with 8V nominal voltage (so 4 batteries in each module, 2 in series, 2 in parallel, that's how they are assembled), for a 24V system. Supposedly with 4.15 max voltage per cell, this would give 4.15x6=24.9V max. I got them relatively cheap from used cars. I can't change the...

I wonder if I need a low pass filter to filter out these annoying transients that trigger my inverter overvoltage protection alarm and shutoff when the voltage from the controller exceeds 15V. It only happens for a few milliseconds when a burst of sunshine from parting clouds hits my panels...
