ave an amp-hour meter in the system, you should talk them into
letting you install one. Of course, if they get 28+ years out of a set of
flooded batteries, they must be doing it right, and maybe don't really need it.

Nathan,
What is the distance between the buildings, and where are the utility meters
located?
What are the sizes of the Services? 200A?
Can both buildings be powered from a single Service? Why is the workshop
metered separately?

have a lockable disco, good signage, and the house meter and shop disco are
close together. You should consult with your AHJ.

I've have not personally dealt with WorldWater, but it looks like they will
only do a complete installation themselves, so it cuts you out of the project.

If it's a well, what is the diameter of the well casing?
What are the peak sun-hours at the site during the darkest time of year that
the water is needed?
There are lots of other questions to ask, but these should help a lot.

Roy has an excellent suggestion...if you have constant AC power available.
In fact, if you use the Grundfos SQE models, they come with a constant-pressure
controller so you don't need a large pressure tank, and it also has dry-run
protection features.

Corey,
The wire ampacity has to be sized for the OCPD, as this is potentially a
bidirectional wire in a fault. While the inverter is current limited, the
grid it’s connected to is only limited by the Service Main, and that 50A
OCPD, which would exceed the ampacity of #10 wire.

the PV array on a 5kW Sunny
Boy, or adding a second Sunny Island and using two Sunny Boy 5000’s. Using
two Islands would eliminate the need for a transformer, and allow for full
array power during grid outages.

Thanks boB and Robin. Good explanation.
I wish that SMA would be more clear on this in the manuals. It shouldn’t be
that hard.
Do other inverters with built-in transfer relays also self-protect against
over-current? I’ve never wanted to try my luck.

Chris,
What is the wattage rating of the wind turbine?
And is that 48-60 VDC directly out of the turbine, or is that what comes
out of the turbine’s “controller”? To put that another way, are there just
two wires coming out of the turbine, or three wires?

Hi Jay,
You are correct about the CU-200. It has an operating voltage range of
30-300 VDC and 90-240 VAC.
However, the IO-101 transfer switch is another story, and I think that is
what Ron meant. Up until recently Grundfos was only importing the 120 VAC
version of the IO-101, but now you can get
1 - 100 of 162 matches
