Enphase is one of my favorite home battery solutions. Its interesting tho because they are arguably the most expensive and least powerful option. Its bad enough they they list kVA on the spec sheet and dont look at the rated line to line phase imbalance. When all is said and done this is what I like about the company and the battery solution. 1. Tech support is awesome. Always pick up the phone in 5 minutes and get you the help you need. 2. Battery chemistry is the safest and longest lasting 3.
