XP1100 sine wave inverter and an Iota DLS 24v 25 amp battery charger. The
system also has an Iota automatic generator transfer switch. The system has
245 ahrs of battery storage and is grounded according to our standard
It is installed in a small home that previously operated on gas lights and a
small generator (Honda 3k inverter gen) for TV, microwave etc.
The television is picking up interference from our system. With the TV
powered by the inverter it has some audible static and visual snow, and
diagonal lines that were not there when the Honda ran the TV all alone. When
the generator is run (without battery charger for now), and the autotransfer
switch loads the gen with the TV, the TV picture and sound are no better
until the inverter is actually shut off. At this point we are back to the
original TV picture and sound before our system was installed. When the Iota
battery charger is on the TV is at its worse state of picture and
The tech help at Exceltech suggested that the 6 foot run to the inverter
using #6 AWG cable (1% voltage drop at 1,000 watts)is too far, that placing
the inverter directly on top of the batteries would clear up the problem.
This we just can't do although we did twist the cables around each other as
also suggested. No relief. The inverter is seperated from the TV by a wall
and by a distance of 16'. The batteries are located in a battery box in the
same large room as the TV and are 14' away.
The tech help at Iota offered that earlier models of the charger had
interference issues but that these had been addressed in the newer versions
(we are told that we have a newer version as indicated by the blue line
under the Iota model number). It was suggested that a jumper wire be added
between the DC negative input to the charger and the ground terminal
(creating a ground loop). Again, no relief.
