Can Zero-Export Solar Really Stop All Grid Feeding?#ZeroExportSolar #AntiReflow #GridTiedSolar

[00:00:00]Is the grid back on?

[00:00:01]So, can it be 100% anti-backflow?

[00:00:06]Today, we pass the case.

[00:00:08]Let me share with you in detail.

[00:00:11]First, let's understand how it works.

[00:00:14]If a countercurrent is found, then it detects and sends it to the inverter immediately.

[00:00:20]Inverter receives signal. Will rapidly reduce its output power.

[00:00:26]Ensure photovoltaic power generation is equal to or less than the local load.

[00:00:31]Now, let me show you the actual case.

[00:00:35]This is the Tiansheng 2.25 kW photovoltaic flight inverter.

[00:00:40]We fix it on the shelf.

[00:00:43]Connect the four-way photovoltaic panels together.

[00:00:47]Then plug in the SEMA 5 communication anti-backflow device.

[00:00:51]Connect to the meter box.

[00:00:54]CT and meter are stuck in separately.

[00:00:57]Then plug it into our AC main power supply.

[00:01:00]Plug it directly into the power strip at home. Plug and play. After the APP connection is set up, we now turn on our load.

[00:01:10]The instantaneous power of this air conditioner is about 3,000 W.

[00:01:15]That photovoltaic power generation is insufficient, then part of our grid will be replenished.

[00:01:21]Now, let's turn off the air conditioner.

[00:01:25]Take a look at the current data.

[00:01:28]Currently, we load only 100.2 to 0.3 W.

[00:01:33]Then the photovoltaic is also generating 112.3 W.

[00:01:37]And we also set up a method for the grid to replenish 10 W.

[00:01:42]Prevent it from back-streaming. So, just to summarize, that is, on the physical level, it has a control response delay.

[00:01:51]From detection to inverter complete drop.

[00:01:55]Although the power is said to be in milliseconds.

[00:01:58]But theoretically, it is impossible to respond in zero seconds.

[00:02:02]But it doesn't affect our decision.

[00:02:05]It does counter current.

[00:02:07]And now usually we use 485 wiring.

[00:02:11]Even a little bit.

[00:02:14]Completely negligible for the grid.

[00:02:18]You can take a look at this specification.

[00:02:21]Therefore, it generally does not pose a risk to power grid security.
