Hello Greg, As Will mentioned, this mode of operation is doable with SolarEdge, but it will require some additional hardware—specifically, you will need an energy meter as well as CTs for each power phase.
Here is some documentation to get you started: - Export Limitation brochure <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> - Energy Meter webpage <https://www.solaredge.com/us/products/metering-and-sensors/solaredge-residential-electricity-meter> - Export Limitation application note <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> You'll note that SolarEdge calls this feature "export limitation" as opposed to simply "zero export." That is because the user can limit the amount of power (e.g., 1 kW, 2 kW, etc.) that is exported - or none* at all. *Related to Jason's point, please note the following information included in the application note (page 24): " “Zero export” term can be misleading at times as one may think that export to the grid is always avoided. In fact, “zero export” mode is expected to export some energy to the grid in some edge cases. The solar systems strives to produce as much power as possible for the site consumption, however, load change events constantly occur. The zero export-regulated system tries to match production-power and load-consumption-power at all times. During the transition periods, some export power is inevitable." -- Corey Shalanski Jah Light Solar Portland, Jamaica On Tue, Mar 30, 2021 at 5:24 PM <g...@remotepowerinc.com> wrote: > > Wrenches, I've got a small system using SolarEdge inverter (4 kW) that > is supposed to go in to a small town that does not allow selling power > to the grid.
