Thread: Shurflo Pump?

  1. #1

    Default Shurflo Pump?

    Interested in using this for my off grid cabin - does anyone know which would be best? have 1500gal tank that we use for rainwater harvesting - need decent pressure to the cabin / garden

    So no need for lift, just pressurizing lines? What power do you have available? They make 12 VDC, 24 VDC, and 120 VAC models. The basic 12 Volt is a little over $100.
    1220 Watts of PV, OB MX60, 232 Amp hrs, OB 3524, Honda eu2000.

    just need pressure - tank is little above the cabin - still debating on 12-24v system

    Actually, most of the shurflos are good pumps in my experience

    I would consider this one for full time:

    Please note, being a moderator does not add any weight to my opinions 300 watts Siemens/BP panels,plus a Sun 90,, making ~400. ~30 amps into Rogue MPT-3024, 450 ah of Trojan T-105, Morningstar ts300 inverter, a Tri-Metric meter.a collection of antique generators, plus 2 Honda eu-1000i's (also a BS2512 IX controller) and assorted other stuff!

    Have one running for 5 years now to a header tank about 10 meters head . Hasn't missed a beat.
    I'm on 1 2volts but would definitely go for 24 if starting again.

    Thanks for the information, last ? How to add it to 24v system if I decide to go that route

    24 Volts worth of battery and a charging system to match?
    Sorry, but not knowing what you've got now or how much the pump will be used it's hard to be specific. Could you elaborate?

    nothing yet - still up for debate 12v - 24v system wanted to start off small with rogue charge controller available in June - 4 T105re batteries - panels still up for debate - as for watts/amp - per day still in the works.

    Just as a sample based on four 225 Amp hour 6 Volt batteries:

    112 Amp hours (50% DOD) @ 24 Volts = 2688 Watt hours power potential
    22.5 Amps @ 28.8 Volts charging = 648 Watts, less typical 77% derating = 842 Watt array
    Quick AC potential estimate: 1684 Watt hours per day.

    Could be better, could be worse.

    The ol' 12 vs. 24 question still comes down to what you expect to have in sustained loads: 1 kW or less, 12 Volts will do. Over that and 24 becomes attractive.

    Were it not for the pumps needed at my locale I would have stuck with 12 Volts - and a much smaller inverter. Skip the electric 'frige too, and I could have used the Morningstar 300. Although that didn't exist at the time.

    I highly recommend the variable speed DC pumps for domestic water. They don't cycle on and off when you barely crack open a faucet, just run slower. I'm using the Jabsco version, the only problem that I've found with it is that sometimes the over voltage protection in it will shut it down for 5 or 10 minutes right before my batteries go to float.(any suggestions?) It works well with the demand heater, the heater doesn't shut off if someone opens a faucet somewhere else.
