It is a lot safer, and allows a mix of batteries to be used together. It also lets a single solar panel charge multiple batteries. Diode can be used to combine a solar collector, and a wind generator to charge the same battery bank.

It is common in a backed up system to diode isolate a battery in parallel with a line powered supply. That way, when power fails, the battery automatically powers the device, until power returns; then the line supply takes over again.

Just trying to get the DIY Crowd thinking of ways to save money, while expanding their systems, simply and efficiently.

Glad you enjoyed it! Be Blessed.
