HI Michael,
Here is another option vs the shurflo.
I had someone buy this and so far its working well. 6 months now.
The shruflo is about $700, this one is $69.

Hi August - in addition to the suggestions below, I would give Iron Edison
a call here in Colorado. They have supplied many gorgeous 200-300 kWh LiFe
systems, and they generally use Schneider products.

You should also take a look at the latest Schneider offering. It is made
for the new grid requirements and has the 600v mppt's along with the
Insight monitoring/remote configuration. Also warranty/product support can
be allowed in to help you if you let them. 75KW and going up I hear.

Hi Bill and all. Windy was having troubles getting this to post, so he
asked that I post it on his behalf:
Bill,
I agree, mostly, with Jay. The Shurflo may last 1-3 years and it is
difficult and expensive to rebuild. It's a diaphragm pump like an RV pump
and has a brush motor. When the diaphragm

Hi August,
The limitation with the Sunny Island, (if you don't go 3 phase), is a quad
stack of 6048s in a 120/240 system last I checked. I think you can double
that with your islanded Sunny Boys. The 6048 had a ridiculously high surge
rating so it can cover pretty high loads.

Hi all, i would keep LG in the mix, and also Pika using Panasonic. My
experiance is only small systems 10 kwh and smaller. Besure to look at
demand charge reduction operation.

Hi Wrenches,
We have a new potential client who wants a 60 kW PV system and a battery
backup system with 200 kWh of storage. The system will be grid tied and the
client insists on some sort of lithium battery technology and doesn't want
Tesla. For such a ridiculously large system, what kind of equ
Hi All,
As Larry said, when a lithium BMS disconnects, this causes a "load
dump" just like disconnecting a lead-acid battery. Well-designed
chargers (solar or otherwise) should be able to handle this without
damage, though a failing or poorly-designed lithium battery may cause
this to happen many
Hello Larry is always a good source. I have used Morningstar MPPT 60 s on
my few LiFe po4 systems 4 years now, no controller problems or equipment
problems yet. I imagine when the BMS disconnects battery voltage high,
controller output goes high for a short period i will put an Egauge on the
outpu
There was some off board chatter about this subject but I think it is useful to
some to copy my comments on the board.
If a Li battery EMS or BMS detects a fault condition, it can cause an open
circuit to the battery. As the battery owner gets familiar with their new
energy storage system, this
