Review: No EPS/UPS functionality and poor customer support - In some use cases I'm sure this could be just fine, but it does NOT operate as advertised. Learn from my mistake - a dual configuration does NOT support EPS/UPS operations. It cannot charge via AC and output AC at the same time and must be manually enabled and disabled. In my case, this was going to be a backup for our well pump but it will not function for that at all. Worse still, when I contacted Growatt they ghosted me. No response at all to my attempts to contact through email for well over a week. ## Features - 【High-Performance Expandable Backup Battery】Connect in parallel for 240V/7200W to power heavy appliances like AC, dryers, and pumps, or use a transfer switch for whole house backup, covering 99% of your power needs.
