A two panel unit for smaller 300 to 350 W panels. Most buyers should get the DS3-L, which costs less.

3.4/5
For a small two panel system that plugs into an outlet circuit where your utility allows it. For a permanent roof array, a 240 V unit has a longer warranty and better efficiency.

Pros
- Plugs into a 120 V outlet circuit instead of being wired into the breaker panel, where the utility and local code allow it
- Built in Wi-Fi reports production with no gateway to buy
- An 18 A input on each panel takes large modern panels
Cons
- Only a 12 year warranty, half the 25 years of most grid tie units here
- 95% CEC efficiency, the lowest here
- Plug-in solar isn’t allowed by every utility or local code, so check first

A two panel unit for 360 to 420 W panels. At the same price the HMS-1000 is the better buy unless your panels are small.
