8 improvements in three-phase string inverters

CPS America string inverter
Three-phase string products have dominated the distributed generation application space while central inverters are starting to be displaced. With this transition, CPS Americas says developers have seen the
following improvements:

1. Cost per watt vs. central down from $0.25 to $0.13
2. Cost per watt with 600 Vdc to 1,000 Vdc approximately $0.18 to $0.13
3. Elimination of DC combiner boxes (included in the inverter cost)
4. Reduction of long expensive DC wiring to central inverter
5. Reduction of inverter mounting costs (no concrete, customized fencing and protection, real estate)
6. Future cost reduction path due to high volume production line economies
7. Easy spares and RMA service model – less severe downtime vs. large central
8. Conversion efficiencies up from approximately 97 to 98.5 percent

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.

We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
