Solar-powered Salt Chlorinators ??

[David00]

Hi,

I'd like to know if there are any low-voltage DC powered chlorinator products that I could run using solar PV power directly (perhaps via a charge controller/battery system) - without having to use an inverter. Any chlorinator that takes a 24v-48v DC input would be fine. This is for a small 42m3 (9,200 gallon) pool where water is being pumped at 17m3/hr (3,700 gallons/hr).

Almost every SW Chlorinator product I have looked at from most of the major manufacturers is designed for mains input (120/22/240V AC), which is no use to me. Something that floats in the pool like the Sun-Chlor product isn't appropriate. The Chlorinator needs to be inline with my pump. I could use a basic chlorinator cell and just power it correctly. But ideally want something that is a little smarter than this and has some metering/controls built in to it. The IntelliChlor might be suitable - although understand that not using their own PSU is an issue (for them).

I can figure out how to connect everything, supply appropriate power, and am not asking for advice on whether this is a good idea. Simply looking for a list of smart Chlorinators that can be powered by a low DC voltage.

Can anyone help?

Thanks,
David.

You’d be better off simply powering a cell (something like a Hayward T cell or a CompuPool cell) rather than trying to reverse-engineer a system designed to work off of standard mains. The hard part is building a simple control system to properly reverse current and energize the cell as-needed.

If you open up the electronics on an IntelliChlor power supply, you might figure out what DC voltage is used on the other side of the power rectifier and simply bypass the AC input and use a small DC-DC converter to get the voltages you need.

I'm bet the amps on these units is small, I would just get a small inverter. You will lose some watts but it will be easy and work great, you can always go mad scientist on it later.

You may consider a bleach injection pump, they run on DC and use hardly any amps. I saw one rigged up for a oil field disposal well and the solar panel was about 24"x24" with a 12v battery. It was a lmi chemical pump in 12v
