Wire Diagram – AC-coupled
Utilizes existing grid-tied inverter and PV panel array – most likely no need to go on the roof
Maximum PV array is 6kW for one JuiceBox, larger systems can be split
Critical load panel is installed with a 60A, 2P breaker to the XW+ inverter
Certified Installer Course – First Grads 11
JuiceBox Differentiation vs Powerwall
POWER: The Powerwall system delivers 2kW power output. 2kW is not enough back-up power for the average home. If one runs a refrigerator and a few lights and then turns on a microwave, it could trip breakers. There is a note on a Solar City statement that it is limited to four 120V circuits. The JuiceBox with the Schneider XW+ inverter delivers 5.5kW and can power 240V loads.
MARKET: The Powerwall as sold through Solar City is only for new installations. With the JuiceBox AC or DC-coupled solution, Installers love the fact that they can go back to their satisfied PV customers and now offer a retrofit. The JuiceBox can tap the 1 million solar homes with a retrofit product.
PERMITTING: The Tesla battery is high voltage 375V DC with an integrated DC|DC. There are NEC code requirements that force additional disconnects and design considerations for any battery over 50V. The knowledge of advanced energy storage varies greatly with Building Inspectors and this could be highly problematic in many locales.
TIMING: JuiceBox is installing now in both AC-coupled and DC-coupled configurations. The Tesla system is not currently available and is reportedly sold out through mid-2016.
CHANNEL AVAILABILITY: Tesla delivers primarily through Solar City where Elon Musk is chairman of the board and owns 24% of the company. While they have announced other partners, access is limited. JuiceBox is arming small, medium and large solar installers across the US with product and training now.
INSTALLATION: With the JuiceBox | Schneider XW+ solution, it is completely validated as a package, is ordered through one part number, self commissions requiring no knowledge of the inverter command structure, and has training and installation materials to support permitting and interconnection to utilities
12
Value Proposition
The JuiceBox installer pricing for 2015 is $9900
Investment Hardware: JuiceBox & Schneider XW+ inverter/charger Installation: critical loads panel, hardware install, balance of systems, commissioning process, time spent on permits Less Federal ITC @ 30%
Value Time of use and real time pricing savings where applicable Back-up power & islanding – dependent on location and personal needs Home Energy Management integration Future demand response participation with utilities Self reliance, insulated from future energy price spikes
