B230 Charging

how can i charge the B230 simultaneously with solar and AC? i know to use the D050S

From the input port, you can only charge one at a time. Solar from the D050S, or from something like a T500.
The only way to charge by two methods is using one of the above, and also through the battery expansion port. In my case, when attached to the AC200MAX, it will also charge the B230.
