I cant see this working well without some battery based inverter

Yes, we're definitely planning a battery based inverter. The real
trouble is when the generator is charging, its AC power passes through
to the loads and hence to the Enphase inverters.
Also I agree with the other poster about Outback being more cost
effective. I just took a look at their
Hi Ray,
With that size grid-tied system, you would want to use a battery based
inverter(s) near the (6.7/0.8) 8000W range.
The frequency shift of the Sunny Islands will work with kicking out the
enphase inverters but you wouldn't get the same output ramping that it
would offer if it was a Sunny
I can't say William. It was only rails, no hardware and besides, we are not
using it. It was delivered to our (out of town) site in error along with our
project's racking which came directly from the manufacturer.
Funny thing is, these mystery rails are from a different mfgr than the direct
Any time we have the opportunity to head to the warehouse and pick up rails
directly, along with the modules, we make every effort to do so. This has saved
many frustrations in shipping returns and turn arounds.

Hello Wrenches,
I've been trying to think through how I can mate some lower cost charge
controllers (prostar 15A 24v PWM units, or the new 30A Midnite solar Brat)
to some 8s LiFePo battery banks.
As I understand it, lithium batteries meant to be charged to around 3.65V
per cell (29.2V for

Couple of thoughts on your application. We used to use the sunny islands a
lot, challenge is they are only 120 volt so we needed to have two or add a
transformer, which proved problematic with the grid tied inverters and hertz
ranges.
So now we use the Outback 4048 and 8048 radians (
