[RE-wrenches] Small scale Maximisers/Optimisers.....

[Jay]

Hi Dave 

I don’t know if you paralleled A battery with the output if you’d damage the LCB. You won’t hurt the pump. 
A diode on the output of the LCB side would take care of that though. 

Might be worth a test?

Of course if you’re going to be putting in a battery then maybe just use a CC/PV instead of the LCB. 

Either method will probably need some kind of shutoff unless youve got lots of water.

They tend to keep the pump operating when a cloud goes over or in low-light conditions.    I think they are available for the 9325 but its probably over-kill for the Flojets.
