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
proba
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.

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

John -- For small RV-type diaphragm surface pumps, I have successfully used
the SunPumps PCA-30 LCB numerous times.
I see you are in New Zealand? I've also used the P-MAX MPPT LCB model
PMAXBT-C, made in Australia. I can't find any contact info for that
company, don't know if they are still around.
Yes they are for positive displacement pumps – and the question was where can
you find them – who makes them…??
Thanks, John

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.

I expect if you shop AliExpress you’ll find these exact items.

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

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 in
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 Dav
Glenn, I don’t believe that UL listing is optional. I don’t believe it’s even
available, nor even desirable, for a small component such as this. For an item
that’s made in small quantities to serve a niche market, and low voltage DC at
that, I can’t imagine what advantage UL listing would offer,
The linear current booster is capable of increasing current on say motor
start-up, once the motor is started, its current needs dropdown. A battery
has high current capability, so I would not expect any advantage in an
LCB. If the LCB is of the buck-boost type you may be able to run a 24-volt
