Avoiding Back Feed in PV Repowering and Solar + Storage
PV Centric DC-DC optimizers like the Alencon SPOTs, which facilitate the DC-coupling of Solar + Storage by mapping the voltage from the PV to the batteries'' charge-discharge voltage serve to block current from potentially being back fed into the panels when there is no solar at night and the batteries are being discharged. Such a topology is ...

BLOCKING AND BYPASS DIODES IN SOLAR PANELS AND SOLAR …
Blocking diodes are used to prevent your batteries from discharging backward through your solar panels at night. Again, current flows from high to low voltage. So during a sunny day, the voltage of a solar panel will be higher than the voltage of a deep cycle battery, so current will naturally flow from the panel to the battery.

What Is a Backflow Preventer? (And Do You Need One?)
Like AVBs, PVBs are backflow prevention assemblies with a check valve and an air inlet valve to prevent backflow. However, they also use a high-pressure chamber between the two to prevent water from flowing backward. The differential is designed only to be overcome by water from the supply side and should prevent sudden spikes in pressure on the opposite end …
