<div dir="auto">I think this highlights my point. Zero export is not "really" zero export in this case and the use of a third-party energy meter to provide net consumption data would surely not qualify the inverter as a listed device for this purpose. While I'm sure most utilities will accept an inverter designed to provide so-called zero export, it's entirely reasonable to expect that some utilities will take an absolute stance.<div dir="auto"><br></div><div dir="auto"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Mar 31, 2021, 12:28 PM Corey Shalanski <<a href="mailto:coresolar@gmail.com">coresolar@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hello Greg,</div><div><br></div><div>As Will mentioned, this mode of operation is doable with SolarEdge, but it will require some additional hardware\u2014specifically, you will need an energy meter as well as CTs for each power phase.</div><div><br></div><div>Here is some documentation to get you started:</div><div>- <a href="https://d1c96hlcey6qkb.cloudfront.net/de1543db-d336-4a89-9a35-dfb08ac7a6c6/316c59969efe4bcd8d98ed461864612c?response-content-disposition=inline%3B%20filename%2A%3DUTF-8%27%27Export%2520Limitation_Residential%2520flyer_ROW.20200727133751107.pdf&response-content-type=application%2Fpdf&Expires=1617321600&Signature=LYeT1QuE0gbaDBl11Khs82CHcxAQ6AwH3ShnOUPy4Mn9wZU2yfp58AV2u5CnXw-Msd39gaIVaeVhLY553LgmA-3OjoLBgnr7D6srKYZXRwxXlN8y24OVc~28jmheitiU~IFgcsxJNyfEFmdueDCzcH1kgN-bXCXD-FDwO5Fr6weysBqw3~6cK0~1A00WUTuwBuQoAbtzWYXhXbrtNf1kYPAYHXI-T10Bc8uvXcapCmUagkNJSjuJW7OSCPUEKtZdV0x1gkKaaocJU3TaQViIKY6Bwrw0qIqo4uBoNyT-rF5Mu-So3Pf4d8fDterfQa2OKHbqIX6RJIzOIBVmRT1-JQ__&Key-Pair-Id=APKAI33AGAEAYCXFBDTA" target="_blank" rel="noreferrer">Export Limitation brochure</a></div><div>- <a href="https://www.solaredge.com/us/products/metering-and-sensors/solaredge-residential-electricity-meter" target="_blank" rel="noreferrer">Energy Meter webpage</a></div><div>- <a href="https://d1c96hlcey6qkb.cloudfront.net/de1543db-d336-4a89-9a35-dfb08ac7a6c6/f0f8ba991b974f37bba1112cce845f09?response-content-disposition=inline%3B%20filename%2A%3DUTF-8%27%27Export%2520Limitation%2520v2.5.20201123105127969.pdf&response-content-type=application%2Fpdf&Expires=1617321600&Signature=Zo3EK-tZ~Zp60hmFWhY-i-6NrpRbAjGXRop5bHutXj8M9EYJgZHIBz2Abtv0H1Rutq9cYv0wkHPwygMMOHgs1kTd-RvDxcrjJ-WVISIStN~HrK6JGKoD3x6pBoNZ7at9PtTn0j4mpiyJ-BtzRRZZNKT1dufsmLxErAa8NUseb89WtmAjaGQIF2ffX6J2QmxcISz4kBzsMS8kZw4Vr-fpDshzgOznzElEInr8CLB5lYmT5Emu2Et~JL47fjLVMCEE3TupX4WTQaJpoU9tr2gQU8YZC6m~dJtbhLouGpkOYb5WiO-BiQbLvjFNk-2uyn3I-ZjLlPjc87xox4krsMs6sQ__&Key-Pair-Id=APKAI33AGAEAYCXFBDTA" target="_blank" rel="noreferrer">Export Limitation application note</a></div><div><br></div><div>You'll note that SolarEdge calls this feature "export limitation" as opposed to simply "zero export."

customer wants to use the power that is generated but can not sell or <br>

up a grid tie no battery system so that it can not sell to the grid <br>

there's an obvious solution I'm missing. Thanks,<br>
