Selecting an inverter/battery system [RE-wrenches]

[Matt Tritt]

Joel,

The first consideration I have is how long has the comapny been making 
the gen. in question and how reliable have they been in long term 
operation.
Is there a reliable and competant service organization to support the 
product IN THE FIELD.
Good generators are usually heavy and, if you are installing them, you 
need to be competant in transporting and scooting around big heavy 
things. :-)
By monitoring, do you mean from a distance?
For on-grid backup, you don't have to be as picky, since all these 
things do is sit there 99.99% of the time. The main thing is that they 
be propane or natural gas fueled.
Grid backup generators generally are supplied with an auto-start and 
transfer switch, which is a pain in the derriere on off-grid prime power 
sets (not auto start, the Xfer).
Are there places for mice to hide and build their messy little hovels 
without being detected until it's too late?
