Re: [RE-wrenches] NABCEP Credits

Wrenches, I am trying to chase down NABCEP credit hours from the Feb 28/29th ALT E Dealer Conference in Waterville Valley, NH. The trainers said they would send the certificates out to folks when they got back to their offices. 4 weeks later and no certificates (needed for recertification for

Re: [RE-wrenches] Combining Solectria PVI 2500 with SB3000

Wrenches, We have an installation in place since 2008 working well with a Solectria PVI 2500 feeding a supply side grid connection. Homeowner wants us to double the system size now. I can buy a SB3000 inverter for $ 300 less than the Solectria PVI 2500 (with upcharge for 10 yr warranty) and I

Re: [RE-wrenches] Battery Experience

We have had less than stellar performance out of the Crown L-16's that we installed 4 to 5 years ago. Premature failure is my experience. About 60% of the cycle life compared to Trojan L-16's and also Surrette/Rolls. I've been using those since 1985. Back to using Trojan. Specifically RE-B's ei

Dave, Sounds like a great solution. We have an OB Radian net-metered PV with battery back-up coming up this fall. Where do we source an "Elkor" meter? Thanks, Dave David Palumbo Independent Power LLC 462 Solar Way Drive Hyde Park, VT 05655 www.independentpowerllc.com NABCEP Cer

Re: [RE-wrenches] Off-grid non-inverter battery charger recommendations?

There is a potentiometer on the board of the IOTA chargers that used to be assessable through a hole in the cover. I adjusted a new one two weeks ago and had to open it up to get at the pot. Adjusts up 15.6VDC with plug in and 14.8 with the jumper plug out. Some of the older models would adjust up

Howie, We have a couple of these out there now. They are good for techno geek types. But for regular people they are no easier than the Mate 2. David Palumbo Independent Power LLC 462 Solar Way Drive Hyde Park, VT 05655 www.independentpowerllc.com NABCEP Certified PV Installer Vermont Solar Par
