[RE-wrenches] small offgrid pv kit

[William Miller]

August:

Off-grid and battery back-up are redundant terms.  If this is for an 
on-grid home wanting battery-back-up, the process of integration involves 
many aspects of an electrical remodel intercepting circuits, possibly 
installing a small load center in an existing structure).  This requires an 
enhanced electrical skill set and may be even more unsuited for 
installation by a semi-skilled home owner than a battery-less grid-tie system.

Kits are problematic in several regards:  Every battery system we install 
is different in requirements and configuration from any other.  The 
components are heavy and a pre-assembled back board can be quite heavy and 
difficult to handle.

I discourage the "kit" approach for these reasons.  If I have qualified 
home owners that want to participate, I suggest they do mechanical 
preparation, i.e. install plywood back-board, build battery box, set pole 
for TOP mount, dig trench, and, at most, run conduit , etc.  We have found 
rocks inside home owner run conduit, so even this simple task requires some 
training-  training which is hard to verify.
