Re: [RE-wrenches] Pentair Pump power

2020-09-23 Thread Dave Angelini Offgrid Solar 
The constant pressure pump types often do not need a big expansion tank. I
did a test on Grundfos and counted cycles with the small pressure tank and
the large. The large tank cut cycles by 1/3. They really are not cycles
like a pressure switch system because of variable speeds.

I have even used a pressure switch on a constant pressure variable speed
pump to reduce cycles at night for an offgrid restaurant. It does work.

Big tanks save big bucks. If you have one, use it!

My experience with the Pentair variable speed pool pumps is that they start
full speed and then slow, which is exactly what you don't want. The well
pumps may be different.

Re: [RE-wrenches] Pentair Pump power

2020-09-22 Thread frenergy 
Just curious, the 120VAC 1/2 HP submersible that has to date been in the 
well for the last 17 years has needed zero service, is there something 
about the Pentair set-up you're referring to that needs regular or 
occasional service?  Believe me I understand your comment about 
schlepping service to some other poor soul, but


Is the Pentair powered with 240 Vac inverter power?

Even better my local well pump installer sells & services it so I do not have

Wrenchers,

  We're upgrading an off-grid water system.  Dynamic head while 
pumping at 20 GPM is 150 ft from water level to wellhead and then its 85 ft 
vertical to storage tank so 235 ft total head to open discharge.  We would like 
to get most of that 20 GPM, we need to know if there is personal experience 
with starting a 1.5 or 2 HP, 240 vac, 2 wire submersible pump against that kind 
of head with an Outback Flex
Power2 (2 X VFXR3648A-01 inverters).

  The FP2 will also be powering standard off-grid loads. There is 
plenty of battery behind the inverters.  If a soft-start solution is required, 
some specifics would be great. Grundfos doesn't seem to have an option for 
these requirements, solar-direct is not an option at this location.

Thanks,

Bill

[RE-wrenches] Pentair Pump power

2020-09-22 Thread Dana Orzel 
If you have 240 VAC look at the Pentair wild AC pumps I have one at 20 GPM and 
am a believer. Tapers on - soft start, varies the volts & amperage with flow 
and tapers the amperage down as it reaches a full expansion tank.

Even better my local well pump installer sells & services it so I do not have 
to! Getting a little smarter as I get older.
