Record margins and 399,000 units shipped in the quarter

The firm's Q2 revenue of $58.2 million was slightly off consensus. Margin improved to 28 percent on the 399,000 units sold in the quarter. Enphase had a net loss of $6.4 million in the quarter and exited Q2 2013 with a total cash balance of $34 million.

The firm guided Q3 revenue to be within a range of $59 million to $63 million at a gross margin falling between 27 percent and 29 percent. That Q3 revenue number is off the consensus estimate, due to inventory in the channel and the succession of the next-generation product, according to the firm.

After years of maintaining a focus on the U.S., Enphase is seeing growth in the U.K. and France, with 20 percent of Q2 revenue coming from outside the U.S.

If Enphase hits the low end of its Q3 guidance, the firm will need a $54 million fourth quarter to best its 2012 revenues of $217 million. Fourth quarters tend to be strong quarters in solar.

At Intersolar last month, Paul Nahi, Enphase's CEO, announced that the firm had a 53.5 percent share in the U.S. residential market in 2012. Nahi said, "We dominate and designed this category."

Here's an incomplete list of competitors and aspirants in the microinverter sector: 

Within the greater module-level panel electronics (MLPE) market, Enphase, SolarEdge (SolarCity is a customer), and Tigo account for 93 percent of the market share, according to GTM Research's MJ Shiao.
