Morningstarr mppt charger ?
Morningstar TriStar 45 Amp MPPT Solar Charge Controller The heat sink dissipates the energy the PV send the CC in the form of heat once the battery are fully charged,is what I was told. Heat is a concern where my cc would be mounted during summer months.
Morningstar PS-MPPT-40 ProStar MPPT 40 Amp Solar Charge Controller This CC does not have the heat sink. How does it handle power once battery's are at full charge?
