24v inverter 32-33v or 48v inverter 65-66v?

[Adrian R]

Hello everyone, I am looking for a 24v inverter, something like mppsolar/pip/effekta, that can charge the batteries up to 32-33 v, and a similar one for 48v that can charge the batteries all the way to 65-66v.

I am thinking about using 4s li ion modules in an 8s or 16s configuration.

I know Studer (and maybe Victron, I am not sure) can do that but I am searching for an inexpensive option.

Any ideas?

Thank you!
