This is my first post. I have this exact unit installed. The Humless Home 6.5kwh unit. Installed it myself April 2020 (just a little before this thread was created.)
Just as someone said above - I have not have a good experience w/ Humless. Works ok, has a few quirks, but generally pleased w/ the unit itself. Their support and documentation however, is *horrible*. Tend to get 1 sentence replies from tech support, and either incorrect or "no help sorry". The manual was clearly written by a non-english speaker & put through google translate or something. Bad grammer, typos etc. For example, the monitoring port. It has built in Wifi, claims to support monitoring...have never gotten it working. Their official reply about it is - "That wasn't included in the final build." ... clearly listed as a feature, but was apparently never included. Their support doesn't seem to know anything about the unit, and just confirmed w/ them, that this unit was entirely outsourced to China, and they basically just slapped their name on it, and sold it to me.
Inverter just failed last week. January 2023. Little less than 3 years after being installed. Their tech support says - can't help. Cannot order a replacement inverter. They say cannot be serviced, essentially told me to buy a new unit. No offer of a discount, no help at all (typical experience whenever I've contacted their support.)
Since this forum is the only place I've found any mention of Humless, I'm going to document my experience with the unit here. Also going to open it up (since warranty is expired anyway), and hoping someone can help me to hack in an 3rd party inverter.
In short - very dissatisfied w/ Humless. More to follow.
