Does this inverter automatically prevent back feeding the grid in a grid down situation?
1768769
Yes, It need grid potential to operate. During utility power outages you solar system is nonoperational.
1768770
No, it only Works grid tied. Once there is no power from the grid, it stops working. It is not for back up systems.
1768771
Yes all enphase inverters are UL1741 qualified they will not back feed to the grid when the grid is down.

I did buy this inverter..it did just what we wanted it to do... we use it for a small solar application on an off grid camp.. our biggest concern was running a small chest freezer converted to a run as fridge with a 5A start up needed. Have not had a problem.

The standby current draw is slight, so leaving the inverter on when it is not supplying power won't significantly drain the source battery over a period of a few minutes.

Both, it support U and EU plugins end it is inverter and coverer!One of a kind :)

Do you check the voltage? some inverters use max 30Vdc and another of 60Vdc check the specification maybe 2 are different. for this reason will be down. I install many of these inverters and continue working

Yep...that is correct. It really doesn't draw any current under no-load. There are no noises, nothing...just the red LED lights for voltage or watts. I have used several different inverters and this one is my absolute favorite...it is a beast and built extremely well. No worries...it is a safe buy. Have had mine running continuously for about 7 months now.

This controller does have a "load" connection for lights or any "Load', but the controllers rating is only 7 amp. Hooking up a power inverter and expecting it to never pull 7 amps would mean the load can't be over ~60 watts which seems pretty low for an inverter, so I'd not try it. Also if the inverter is running anything that has any kind of "surge" load, the controllers rating needs to be able to handle that too, so it doesn't sound like the best idea to have an inverter running through a controller like this (I've even seen the inverter alone create a fair arc as I connect up the wires to batteries because of charging capacitors). If you're pretty sure you have a steady load that will be under 20 amps at 12V, then there are controllers rated at that, but I'd not try it with something under ~20 amp rating even for a 100-150 watt inverter (which is almost the smallest size for inverters).

Yes but there is a long delay. You might try a regular 120v contactor, with the coil electrified by batteries and when your battery bank/inverter drop out the coil let's go and automatically switches to the other input which can be shore power. Then there is no interruption in power. But put sensitive electronics on a surge ups and everything will work great. That's what i do. When my batteries are charged enough they kick in the inverter which powers the coil and closes contacts to feed my load from solar. Then at night after they drain and voltage gets too low they switch back to shore power, with no interruption to my loads. Yes but there is a long delay.

Not aware of any issues concerning DC Solar inverters as it runs on AC current. You plug it into a wall outlet and go.

that is an inverter issue. a wind charger or solar panel just produces power, but the inverter decides what to do with it, ie charge battery, and if there is excess, and your meter allows, then you can run your meter backwards. fyi i am hearing that smart meters may not allow this the way the old meters do.

No, it is just a basic 1000W inverter. I think you are mistaking an inverter for a Universal Power Supply (UPS) that has a small battery in it to keep your electronics running for a short time in the case of a power outage.

Yes it does, it autosenses 110v or 220v. There is no switch on the back for this, the PSU handles this itself

My grid tie 300 watt inverter is connected to two 150 watt 22 volt panels. Working just fine at that voltage. The previous one burnt out with three panels connected to it. Apparently the voltage and amperage had increased when at full sun. I would consider de-rating all voltage values to 80 percent on any inverter you purchase.

The same solar panel can be used in an off or on grid system. An off grid system is not connected to the power company and usually stores the electricity generated in batteries for use when there is no sun. The on grid system is usually connected to the power company with an inverter that changes the dc current produced by the solar panel to ac current. An automatic switch cuts off power to the grid if the grid goes down to prevent power back feeding and endangering worker. That also means that unless there is on site storage, batteries, when the grid goes down so does the on grid system.

Yes you can connect the inverter to a Breaker as long as the circuit panel is off grid

I only wish I knew.It just runs on a regular current....I do not know what an inverter is. I sure do like mine under my desk.
