High DC Ripple, Quattro 48/5000/70 and BYD Battery box 13.8

Actualmente tenemos una instalación con 4 inversores Victron Quattro 48/5000/70 y dos BYD Battery box 13.8, el sistema esta configurado como back up.


La residencia mantiene fluctuaciones de voltaje durante el día, y en algunos casos, las mismas dan problemas de High DC Ripple.


El sistema esta conectado de forma correcta con su cableado y torque correcto.

Could it be that lithium batteries have higher ripple at lower soc?

I have noticed a higher ripple at the tail end of the discharge curve where the battery voltage drops rapidly. I have built a 16s 6p pack from nissan leaf modules and DC ripple sits at 0.2v @ 100amps from 64-60v then rises to 0.4v below 60v. I will recheck this and see if it was'nt just my imagination
