I talked to a power supply engineer and he confirmed the MPPT board I bought is a cheap one that can only charge #batteries.

He also pointed me to a high quality MPPT board that can tie together #solar, +5VDC, batteries and output +5VDC. It handles everything: the charging profile of the batteries, voltage conversions, and switching between sources.

So I orderd one, naturally.

If it works as expected, I'll have go revisit the power situation on the RAK side. No point in having the solar/battety power block if I don't need it. I'll keep everyone posted.
