I signed my contract with Longhorn Solar at the end of August 2021. Here it is September 27, 2022 and my system is yet to be installed where it will pass even a simple test of turning off the Grid power and seeing how long we can live on our Sonnen EcoLynx20 battery. Test FAILED at one hour and it powered down the whole house with 86% battery charge showing remaining. Attempted to address this issue with Sonnen, whatever changes they made powered down the battery completely. I was told I could power the battery back up and all should be well. Not a chance, battery will not power up, we are dead in the water as far as battery backup goes. Sonnen said that given it would not power up I needed to talk with my installer to remedy the situation. I contacted them over 10 business days ago and copied in everyone I had an email address for and all I have heard is crickets. Today we heard reports that thousands of folks in Austin are without power, luckily not us, however my wife heard that story and she is not at all happy and called Longhorn today to receive a message that the tech support folks had forgotten that we were down. If you decide to go with this company demand a 40% 30% 30% payment schedule, holding 10% of their final payment is not enough to even get the time of day from them with their standard 20 40 30 10% schedule. So as it stands now they have 90% of my money and I have no battery backup, no solar feeding into the system when the Grid power is turned Off and a very unhappy wife. I'm not very happy either and today my patience has ended also.
