Well, I have two different battery groups to connect to the 24-volt inverter, the first group consisting of 10 2.4-volt batteries and another group of 4 12-volt batteries, the first group is already connected and works perfectly, but I want to incorporate the second group to the inverter, to increase the load capacity. The question is: Is it possible to add the second group of batteries to the inverter if they are different? Greetings.

If they are of the same voltage there is no problem to one that is not advisable to mount batteries in parallel. https://www.monsolar.com/blog / do not connect-batteries-in-parallel / https://autosolar.es/blog/aspectos-tecnicos/por-que-debemos-evitar-la-conexion-en-paralelo-para-las-baterias
