I am working on a project that requires someone with more experience
than I have in generators and transfer switches.
Would you please contact me off line if interested
Currently
Utility fed house with two 400 amp panels. Maximum total house current
drawn over a long monitoring period is 20
Wrenches:
I got an inquiry today from a fellow in Lead, SD, 57754, who had a system
installed at his remote cabin (in the Black Hills)... He really needs
someone more local to troubleshoot for him; if anyone does work there or can
recommend someone to help this guy, please contact me off list.
Hi gang, just a reminder. If you have any questions, please respond
off-list.
Some time ago, the Wrenches reached consensus to not have leads on this
list
1. If you get a lead you cannot handle, then either send it directly to
someone you think will be interested (but not the list) or,
2. Send
A house with 2 x 400A panels draws a maximum of 20A? There's something
wrong in your numbers.

Hi Wrenches,
We are bidding on a project to provide several hundred small (75Wpv, 120AH
battery) 12V DC off-grid solar home systems for rural villages in West
Africa. The project planners have requested that the systems be designed
and built to provide 7 years of battery life. That seems crazy o
Eric,
Yes, one of the classic problems with small systems and less
educated users. Just a small contribution: it would seem to me
that in this case the LVD setting is as key as the LVR. What if
the LVD was set as high as possible - say, 12.0 V with sealed

Eric,
Allan's recommendations on both points are excellent, and spot-on.
I would add the following suggestions for your controller and system if budget
and circumstances permit:
1) Use a MPPT model controller to enhance the recharge rate under
less-than-ideal conditions. The PV is already un
I agree with Allan and Dan, and would also add that modeling the
performance in some type of software would also be important.
Both PV Design Pro (now apparently obsolete) and HOMER allow you to set
on and off set points based on SOC. You can literally see how the
battery is cycled to predict i
