Can this unit be programmed not to power an appliance (my solar pump) if little or no sunlight is available.

I could never get the unit to actually work as the instructions were not in English....worthless IMO

No, the unit is not that complex and there is no programming feature. However, if there are not batteries in your system, little or no sunlight will translate into your pump not working anyway. I hope that is helpful.

It is not programmable. If there is little or no sunlight it just won't be able to charge your battery.

I have only been able to use it as a regulator that shuts down before draining your battery. I think you would need to look into building some sort of photocell cut off relay.

You can't unless you get the blessing from your local utility company. If you do,it would take a little more watts than the unit provides. Works when the sun shines only.

Yes, but it will require that you create your own island, so that the Enphase will detect the power, and start. You then have to deal with dumping the load that is not used. Do a Google search. there is whitepaper on how to do this with Magnum inverter, battery, and Enphase.. Magnum is also working on such an inverter that will deal with the dump load, but at the end of the day, this is a "grid tie" inverter, so any power that is not used has to go someplace, and if you can't feed it back to the grid, you need to get rid off it ... There is a gentlemen on Youtube that has complemented his solar with Enphase, and Magnum inverter for emergencies, and he is using halogen lamps, and heat guns to dump the load ..... So, it can be done, but it requires a lot of design consideration, and extra expenses that have no real ROI for being off the grid.

None that can programed. It will not come after sunrise unless it is very overcast outside. In the evening it will come on only after daylight has faded.

Yes, that's exactly how it works. You can plug any regular appliance A/C cord into the unit and it will run it as long as the appliance is not too energy hungry (i.e. < 100 watts). This is a great portable unit and I highly recommend it.

Yes, that is what I use mine for. Place it so that it gets the most extended hours of sunlight possible and you are set. I have never run out of power to my gate since installing it, but if you did, you could add another one into the system as well. They are an awesome deal for the price.

what is the draw for the pump? I assume the pump is 110v AC so you will need an inverter also. You may need more than one panel do you want the pump to only run when the sun is shining? if not you will need to store energy in batteries.

not sure, it is easily bypassed to run all the time the sun is out, it is a standard bi-metallic switch available at any heating supplier, in a variety of temps. my unit functions well and have had no problems.

This unit is not solar powered I believe that is the product name. It requires 110 volt power via a wall outlet in order to function properly.

You can attach it 24/7, but when there is no sun, the system is consuming from the grid (just few miliamps). I'm using a heavy duty timer to turn my 4 units off during night time...

Maybe. One of the nicest features of this timer is that it comes preprogrammed out of the box to go on at sunset and off at 11pm(?). I found that cycle perfect so didn't need to program. Assume if the power goes out the default setting will always be there but not sure if you were to change the default. My guess would be yes based on experience with other similar ones but not sure.

I've had no issues with it working. Again as stated by the others the solar panel has to be in direct sunlight. Make sure the pump has been connected properly & it should work.

Yes you can, however if you don't have a analog meter box from the power company it will only offset your immediate use during the day when the pv array is receiving sunlight. Your power company can install a meter box that will remember how much power your back-feeding to the grid, if your meter is digital, you should contact them first in that case. Analog meters will turn backwards if backfed.

The inverter should handle the start up spike just fine and the normal pumping will not be a problem. You might end up being a bit lean on your energy production with just one solar panel, depending on your energy draw.

Hi: I am not sure if that will work. I think that the meter that detects if it is light out (so that it knows when to turn on/off) is in the light unit and not in the solar panel. You should be ok if the light detector is in the solar panel. Hope this helps.

It can not use solar but it does have 12 volt input, so you could run it off your car.

I run mine thru my inverter so that it will work when I am unplugged from shore power. Good luck
