El Sid 10W DC pumps are great but in my experience they did not have the flow
and head “oomph” for long runs for the zones on our second and third floors
with our hydronic heating system (wood boiler). In our off grid house we
installed El Sid’s on all 4 zones in the late 1980’s. We had
I have multiple ElSid pumps in my heating system which have been running
for just about 15 years without the slightest hitch. At 10W each they are
hard to beat, but they do need DC so a power supply is needed. I ran them
off 24VDC direct from the battery for the first 10 years and from a small

LG batteries are not approved for off grid use at this time, and the only
inverter they work with so far is the StorEdge which is not an off grid
inverter. This pertains to the high voltage units anyway. And, I'm not
aware of anyone bringing the 48v units into the country yet. Either of

you can use a battery charger direct to the genny, we have had to do this
with some projects that could not have any interruption during a switch
over, this was on a OutBack and could take a genny input, we sent it
through a CT for the FMDC and mate. Different animal same solution
Hi Chris,
In regards to wattsun, which controller are they using? The website doesn’t
give any details.
The last one I did used a quite complicated one and it didn’t have easy to use
external manual controls.
Thx

Agreed, use long term off grid manufacturers gear, I can’t recommend
reinventing the wheel.

I would highly recommend using proven equipment from the long term off
grid companies: Magnum, Midnite, Outback, Schneider, etc. and stick with
a DC coupled array and lead acid batteries for now. I just got back
from inspecting two Li+ off grid systems done by a GT dealer, and I saw

Wrenches,
I am trying to design a Pika off-grid system. The issue is that they
currently have no way to charge from a generator. Has anyone ever
installed one set up for zero grid export and connected the generator to
the grid input?
Would LG chem or another manufacturer be a better choice?
Yep, I wouldn't even consider roof mounts 15 years ago. Fall danger,
leaks, I'm an electrician not a roof jockey Of course the mounts,
racking, etc have improved vastly, and now I have a substantial ladder
collection. I still prefer a good ol' pole mount for installation, I
just can't
Dana,
Your comments, and other comments on this list have made me see the
light. We are going to go with a boiler.
What is the best source of equipment for this application these days?
Many years ago, I helped install a system in Colorado using El Sid
pumps, with guidance from you, if you
Amazing what the difference of $10.00 a watt to a $1.00 a watt for panels makes
in the design !
Still don’t like poking holes in a perfectly good roof !
Just another set of random thoughts,
