I agree, I would do one or the other. The main point to using a LCB is
so you don't have to have a battery. A battery system is going to be
much more versatile, and could allow an LED light, or even a small inverter.

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.

Thanks Jay ! I have project where I want to install a pump in a tank
for remote watering. If the LCB is used, have you ever tried using a
small ATV 12V AGM to allow the pump to run in wildfire smoke or at
night? Just a switch to parallel the the LCB?
Anyone tried this? There are a bunch of LCB's on amazon also.

Hi John
Sunpumps makes a really good one.
Here is a ebay link showing many of the new probably Chinese (not
saying they are bad) but they are way less expensive than the US
versions.
https://www.ebay.com/i/293234996712?chn=ps
I expect if you shop AliExpress you'll find these exact items.
Cheers

Yes they are for positive displacement pumps – and the question was
where can you find them – who makes them...??
Thanks, John

Probably an RV water pump? And an LCB should work. Who makes a good
LCB for this Jay?

Hi john,
I'm not sure which pumps you are talking about. Are these
positive displacement, and if so then an LCB is what you need.

Where can you find some small maximisers/optimisers for a
solar-only pump. This would be for a surface pump like
the Flojet 11, 12 or 17 litre/min pumps. 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.
Cheers for suggestions – John Veix, N.Z.
