Peter,I did a 15kW BIPV install on a home with GE Geko modules in two stages,
first (7.7kW) in 2006, and second (7.33kW) in 2008. The 2006 modules were 55 W
and the 2008 mods were 66 W. I wasn't too impressed with the quality of the GE
modules and would prefer not to use them again, which is

They are supposed to be mounted outside boxes so that you can clearly see
when they have been used up. Sand makes glass that expands and breaks the
plastic. They used to be porcelain for the very same reason. If you are
concerned about unqualified people coming in contact with

I don't want to take your money, but I am sure I could, if I had the time

but they are not nearly as extreme as you make them sound.
You did not even mention the #1 reason to use Enphase, however,

I know, as Bill pointed out, that the Deltas are supposed to be mounted on the
exterior to allow the damage to stay outside of the combiner box. But I've also
seen a lot of old Deltas damaged by the sun, and seen them cracked off at the
1/2 nipple attachment point, which then leaves exposed
Hi Jeremy,
They'll need a lot more than that.
I suggest you contact Thompson and Howe, they make control systems for grid
direct hydros.

You might also have to contact Canyon industries about the right motor and
drive parts.

Jeremy,
You can use a PV Powered inverter if the Hydro is in range of the sizes
they make. You just need to rectifiy the AC output of the hydro. They
are very tolerant of spikes and load changes in the house. You will
also need a device to prevent the voltage from exceeding the maximum
Jeremy,
Not sure if this would work. but How about feeding the hydro output
into a large industrial battery charger or chargers. They are available in three
phase.
Modify the charger by eliminating the stepdown transformer. Basically what you
need is a rectifier. Then feed the resulting
If the hydro is small I think I would try rectifying and putting into a charge
controller. and then use an Outback to make grid power. (GFX) Each charge
controller would need its own rectifier. never parallel charge controllers on
the DC input side. This is only helpful if the hydro can
