### 1/5 — Noob

*2023-05-08*

Money wasted and no good explanation battery can’t connect in  serial

**Developer response:** The app only "allows" you to connect batteries in series if you choose the correct battery voltage rating based on the chosen system voltage.

### 5/5 — Suggestion

*2022-05-16*

Can you please allow me to enter manually the rates for my batteries and panels.. 

For example I’ll like to use 400w panels 

For the batteries as well.. can it support lithium configs ie 10kwh etc?

Solo cuenta con pocas opciones de modulos y baterías respecto del mercado. La aplicación deja de dar la solución requerida.

Les falta calcular la producción para un año con la utilidad, calcular el sistema para 48 V o más y los costos. Son importantes.
