I'm back looking for guidance from the great and powerful members of this forum.
I've got what I'm calling a phantom voltage.
I've completed all of the wiring and equipment installation. The 9.7 kW array was pushing 9+ kW into the batteries a couple days ago as a test.
I was working down the AC part of the Sol-Ark commissioning checklist when I came across my phantom voltage. Once AC power has been applied to the Grid terminals the checklist says to check for 240v between L1 and L2, 120v between L1 and N and L2 and N, 0v between Neutral and Ground and then 0v between Grid L1 and Load L1 and Grid L2 and Load L2. Well, every thing else checks, but I have approximately 70v between Grid L1 and Load L1 and likewise between Grid L2 and Load L2. The Load circuit breaker is off. I have a xfer switch installed so that I can switch the house from the utility or Sol-Ark output. I have to this point continued to run the house off of the utility - I have not moved the xfer switch to supply the house with the Sol-Ark so the Load wires have not been powered yet. I disconnected the Sol-Ark Load wires at the Sol-Ark and at the xfer switch. When I connect power to the Grid connection of the Sol-Ark I still see the 70v phantom voltage as described.
So am I seeing induced voltage in those wires? Is this normal? If not, any ideas on how to get rid of it?
Thanks for any ideas,
Lowell
