Kirk,
I have 4 Eco-gens out there and working fine. I'm not sure about the
phantom load but it does include the battery charging. My guess is that after
the battery recovers from starting, the load probably drops to minimal. There
is an hour meter in the menu under "state" which is many keystrokes to find.
Took me awhile to find it. Other than a possible ghost load problem, my
customers and I really like them. Quieter and more fuel efficient. However,
for larger off grid systems with really big loads, it may not be strong enough.
Time will tell. I have one wired at 240 and the others all at 120. We did
have a problem with one of them with a faulty rpm sensor. I found that the
authorized service from the middlebury outfit... Taylor Rental or green Mtn
rental... Not sure of the name... Was excellent. No charge to the customer
under warranty and fast service. P
John
