Friends:
Just a heads up for those of you installing Enphase systems:
After installing over a dozen systems we came up with a job where we have
been unable to resolve interference issues. The problem is receiving data
from the inverters into the Envoy. We have tried relocating every
component, using multiples of the ferrite beads, various models of X10
filter modules, etc.
Enphase has been trying their best, remotely, to help resolve the problem
but without success. The interference is being caused by an expensive pond
pump (or we would have a new one by now). We are awaiting an AC filter
module from Digi-key. I will let you all know how it turns out.
In the meantime, I have added the following paragraph to my contracts:
Data systems: Some new inverter systems transmit data over your
power lines. On rare occasion interference from your appliances will occur
that block this data transmission. We can resolve these problems but there
may be extra charge for our time and materials.
My profit from this job has evaporated. I am writing this because I don't
want to see any of you in this situation unknowingly.
More later,
William Miller
