PV OUTPUT DATA

DECEMBER, 2012   BACK TO OTHER INSTALLATIONS HOME PAGE

This is Anne's system. Grid tied 12/21/2012. SB4000US to start and we will add another inverter in a year or two, to increase output to meet home demand in full, year-round. 5 KW Eoplly solar panels tied in two strings into the SB4000US. Hadley Sawmill installed the boxes and wired all grid connection wiring. The owner installed panels on their roof to save labor costs.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Rooftop PV panels. SMA SB4000US grid tie inverter. Room in the DOG HOUSE for a second inverter. Planning ahead for future expansion can reduce initial system cost by investing every year or two instead of all at once.

 

 

 

Utility engineers inspecting wiring and voltage as they add each KWH meter. Finished!! AND GRID-FEEDING!!

 

 

 

All boxes open for inspection. The AC combiner/circuit breaker will allow easy future addition of a second inverter. Dedicated KWH meter for system output only.

 

   

 

Home and system main disconnect. Dedicated home usage KWH meter. Utility connected NET METER.

This utility required three separate meters to log every aspect of system, home, and net metering. Not all utilities require this. Be sure to talk with your utility before beginning any project. Greg Hadler, owner of Hadler Electric, is the electrical engineer who makes sure we meet code before the utility engineers get here. He works with us on every grid tie project and signs the utility agreements for our customers. Hadley Sawmill supplies the solar panels, inverters, boxes, and any other parts needed. Hadley Sawmill designs the systems and can be hired to consult and/or install part/all of the system, depending on the customer's level of experience and comfort with electrical installations.
