Boosting MPPT solar charge controllers are pretty rare. Normally it’s beneficial to have your solar panel voltage higher than your battery voltage, but that can be difficult if you need a high voltage battery system.
This cheap MPPT solar charge controller boosts the solar panel voltage up to a higher battery voltage and is sold primarily to the eBike community.
