I’ve ordered a Rachio 3 which is on it’s way from the US via Amazon - I’m Australian based and will do all the necessary mods to get it working legally.
I don’t have grid power anywhere near the location of the garden/lawn the Rachio 3 will be stationed thus I’m thinking of creating a simple solar/battery setup that will be enough to power the Rachio 3.
Has anyone done this? Any advice?
I’m hoping to keep it simple:
- 12V 100watt panel
- 12v 10AH battery
- MPPT solar battery charger
- DC>DC Step Up converter to keep the unit powered in 24V (like this: https://www.jaycar.com.au/dc-to-dc-step-up-voltage-converter-module/p/AA0237).
Any advice will be greatly appreciated.
Not sure that is going to work as I think the Rachio needs a 24v AC power supply, not DC…
I have not done this, but maybe a 12VDC to 24VAC inverter may be used instead of the DC to DC step up converter.
Thanks Pedro - This unit looks to be a winner - inv-12dc-24vac | PowerStream
Hi Tomas, @Pedro noted the some thing. Thanks both for your suggestion. inv-12dc-24vac | PowerStream looks to be an option.
Hi, just want to find out if you got it working?
Yes - I’m now running a number of items off 12v DC charging via solar.
- 1 x 300 watt mono panel
- 1 x 100ah sealed battery
- 1 x 20 amp charge controller
- 1 x 500 watt 12vdc/240ac inverter (this runs the rachio)
Off native 12vdc I run garden lighting, pressure pump for sprinters, CCTV etc.
I presume you mean a 24VAC inverter, not 240AC.
Nope. It was cheaper to go 12vdc>to240ac in an inverter - $40AUD for the 240vac inverter vs $240 AUD for the item from Powerstream. For the sake of a small amount of inefficiency that doesn’t bother me I couldn’t justify the extra $200AUD.
Okay, you said what I was thinking about going to 240VAC and then back down to 24VAC, but costs are definitely a consideration.
