GT with Batteries (was SW Plus) [RE-wrenches]

[Bill Brooks]

Joel and Allan,

Always one to contradict blanket statements, I have to say that I am
extremely pleased with my pre-GTI SW system. Knock on wood, it has performed
flawlessly for over five years. I think that is signficant. With the
adjustment made to make it run more efficiently, with C-40s and a low fill
factor AstroPower AP-120 array, I'm a satisfied customer.

Personally, I think Outback, SMA, Beacon, Magnatek, and EVERY JOE'S INVERTER
HOUSE (no such thing in case you serious people are wondering) have a very
tall task to beat my system.

Can it be done--Absolutely. Is it easy to post the reliability numbers of
the SW--no way. Remember that an inverter has to work to make electricity
;-).

Bill.

Allan,
I agree. When I installed my pre-GTI and several others and a few
non-battery, big-blue-cap SW-series inverters, they were the only thing
available. What a difference a few years makes. SMA has made a big
footprint in the silicon and Outback is the favorite of techies. Still no
"appliance PV" a la HVAC, but good HVAC is almost always a site-specific
professionally design. When I get around to it, I'm going to replace my C40
with an MX60. When my SW4048 joins the ever-growing landfill, I'll probably
go batteryless PV and put in a separate UPS. Customers don't understand
that the California PV rebates are for "Emerging Renewables," but wrenches
sure know. Onward through the fog.
