<div dir="auto">We have had numerous SolArk 15k's with loose neutrals direct from the factory. Double check all the factory connections in the accessible wiring compartment.

Definitely sounds like a loose neutral on the utility side (likely at the pole/tap).
<div> </div>
<div>I suspect if you turn off and disconnect the Sol-Ark the light flickering, etc will continue (until the utility recrimps their neutral...)</div>

<p class="v1MsoNormal">Customer has for two days been having grid voltage issue seen as dimming lights. No neighbors reporting issues. He called his electrician who noted one high conductor and the other low. Have seen this before unrelated to solar and it was a bad neutral. His electrician says ok.<br /><br />Customer disconnects from the grid because the fluctuations so severe and when he does, voltage issues go away and Sol-Ark is rock steady at 120-volts per leg. I send my senior tech over to ensure we don't have a loose neutral or any grid conductors to the grid input. Nothing found.<br /><br />Picture attached of grid voltages from the Sol-Ark monitoring (very helpful, I might add.)<br /><br />The electric cooperative is sending a tech out tomorrow.
