I have a 12 V, 24 Ah lead-acid battery that I have to charge using a solar panel.
My initial solution to the problem was to implement a buck or a buck-boost DC-DC converter with MPPT and control the charge by sensing the output voltage and current. I then realized that when implementing MPPT I can not keep the output voltage constant.
The alternative to this is to use a casacade boost-buck converter to charge the battery, that way I can simultaneously implement my MPPT and charge controller independently. I can use the boost to control MPPT and the buck to control the charging, is this a feasible solution? If not, are there any alternatives, especially any involving single-stage configuration?
