the MPPT window starting at 200v instead of 250v, which is a significant
improvement.<br><br>

<dd>>> Hi Dave and All. <br>
<dd>>> <br>
<dd>>> Reasons for HV batteries off grid? <br>
<dd>>> <br>
<dd>>> 1) Smaller cable size (I just did an 18 Kw off grid with 4
SIs and the<br>
<dd>>> cable costs alone were in the order of $400) and increased
flexibility<br>
<dd>>> locating batteries and inverter. 10 AWG plug and
play.<br>
<dd>>> <br>
<dd>>> 2) Higher efficiencies. Easy integration on the DC
bus.<br>
<dd>>> <br>
<dd>>> 3) Integration with GTBB battery tech and systems. Why have
two<br>
<dd>>> standards and two sets of equipment? The line between
Off Grid and<br>
<dd>GTBB<br>
<dd>>> will blur as more GT customers want more storage and more
Off-grid<br>
<dd>>> customers want the option of grid hookup at some
point. For<br>
<dd>developing<br>
<dd>>> countries as off grid micro grids grow they can merge.<br>
<dd>>> <br>
<dd>>> 4). Integration with Electric Vehicles as storage for
either GTBB or<br>
<dd>>> Off-Grid - can integrate on the DC bus seamlessly.<br>
<dd>>> <br>
<dd>>> These are the reasons that seem obvious to me. I\u2019d be
surprised if the<br>
<dd>>> manufacturers are not thinking this way. Though you may be
right as I<br>
<dd>was<br>
<dd>>> surprised that Outback went 48V with the Skybox. And it\u2019s
been a hard<br>
<dd>>> sell to get SMA to support US off-grid. If the equipment
could do both<br>
<dd>>> seamlessly they would have more market.<br>
<dd>>> <br>
<dd>>> And High Voltage safety is not really an issue with proper
(standard<br>
<dd>>> electrician) training and as the only electrician or
customer interface<br>
<dd>>> is a plug or set of small non-energized terminals. Having
high voltage<br>
<dd>DC<br>
<dd>>> in you car is more dangerous. House fires are caused by
amperage leaks<br>
<dd>>> (much higher in Low V) (and shorted PB-acid) way more than
voltage<br>
<dd>leaks.<br>
<dd>>><br>
<dd>>> <br>
<dd>>> I\u2019m off to SPI. I\u2019ll ask them . . From what I understand
Pika is<br>
<dd>heading<br>
<dd>>> that direction. I imagine Powerwall too if they ever
decide to support<br>
<dd>>> off-grid.<br>
