Great after sale & prior installation service

After receiving my unit I wanted to make sure I had V2 vs. V1 since I was planning on doing a firmware check upon installation as well as plan for a second unit. After a phone call and email to both EG4 and Signature Solar, both Tyler and Layla were able to confirm my unit was a V2 as well as address generator options. The bottom line is simple: Both folks were courteous and understood my concerns as well swapped photos, etc. without taking a ton of anyone's time. I feel more confident in a long relationship with SS to be there when I have REAL questions but luckily the included documentation is VERY simple to understand for anyone including a near retiree like me. I plan to add a second unit to give me a 240v single phase option or just more capacity. So IF you are on the fence about off-grid backup that does NOT break the bank I can say this little unit may be the easiest method to check that box. Thanks again Tyler and Layla for promptly answering my concerns. I won't add a photo since it's on the website.

Perfect and forgiving beginner unit

Last week some cold weather hit NW FL and my unit alarmed and kicked off. When I checked it, the VOC had reached 503. I know that the maximum VOC is 500V and that the voltage increased with lower temperatures but I have not read or heard that the unit would shut down to protect itself from an idiot like me who always wants another panel in my strings. Currently running two refrigerators, two freezers, 2 TVs, lights, cameras, and a RV (AC off) and has been bulletproof and dependable. Just installed our second unit yesterday and will be running our entire house in a few days. THANK YOU SIGNATURE SOLAR!!
