what is the difference between the "off grid" and the non off grid panels?

"off grid" is a moveable panel.... non off grid panel is one that is mounted. .. Off grid, such as on a camper van

I am not sure how panels would be off or on-grid, but systems are. off-grid require a battery because you don't get sun 100% of the time, and some days are cloudy so you store excess power, on-grid do not because you still have the grid. these panels should work for either.

Hey John, the difference is semantics, different words to say the same thing- don't worry about it. Jim

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.

Enphase knows that the temperature under the panels can get much hotter than the "outdoors temperature for the day." I believe the temperature they are referring to as "ambient" is just the "outdoor temperature for the day", the "weather temperature" if you will. So +65C pretty much covers any geographical location in the world.

The solar panel does not store energy in it's self.The batteries are charged by the solar panel for using the light at night. So no models without batteries at this time.

They don't require electricity--unless you want to run the fan. They do require a battery to run the thermostat and electronic ignition. I am "off grid" and haven't used the fan. I'm heating a 400 sq ft space and haven't felt the need to use the fan. The low setting is all I've ever used. Having the thermostat has been very helpful, as it turns the heater on and off and keeps the space from overheating.

It gives location/ grids anywhere in the world based off of where ever you are, it just depends on the grid system you'd like to use. Hope this was helpful

The specifications for each are online. One has greater wattage and runtime and projects a longer distance. You can compare to determine which one would suit your intended application.

Yes, it can be run directly off the panel. I have set up a number of systems like this.

Yes all enphase inverters are UL1741 qualified they will not back feed to the grid when the grid is down.

Agree with Todd & Kate. It is what it is, a "solar" panel depending totally on UV rays to generate a charge. The panel will not generate a charge at night nor on dark overcast days.

They are both good. However batteries are expensive. I only use batteries if I need power. If I want to lower my electric bill I go straight from solar panels to grid tie inverter to outlet receptical. Remember the shorter the distance between panels to inverter will produce more current or watts back through the meter. One more tip make sure your inverter is at least equal to your solar array. 500 watts of solar panels will only put back about 350-375 watts of power.The batteries if run in parallel to create 24 volts will put back about 480 watts. Hope this helps.

It uses regular household power. I live off the grid and am able to power it through my inverter without it blowing a fuse, this is a huge plus!

No difference to me. I have the electric one at the office and thinking of going to this at home. So much safer and if you forget about it it shuts off. If you want to reheat, just turn it back on

"No" to both. If you have two 6V batteries and hook them up in series, the panel will work. This is a "battery maintainer" and has no sophisticated electronics other than a diode to prevent reverse flow/battery drain at night.

I can't say for sure that it's the same panel. I would recommend going to www. Parallax power.Com and review the specs. I can say this panel was a great replacement for my camper. The deer had it installed and tested in less than an hour. Sorry I'm not more help but I don't want to lead you wrong.

Checking Aeon Labs website, the only difference I can find is that the DSC19103 "includes energy monitoring features". I believe that some control systems can utilize that information.

you can probably find better answers on az wind & sun forum. i read that you have to choose your grid tie, to be compatible with the panel and there are various makes and models. if you choose a watt size, you also have to be aware of the 12v 24v 48v etc capabilities. If you are going to hook the panels in series or parallel, and how many panels you ultimately want. thus far, you have to do the usage calculations for your max & min energy needs. then your system. if you are tied to a grid, then the tie makes sense. if you are off grid, then you need to hook to the controller/inverter set up. there's more detailed information to make your choices. you at least have to start with your consumptions, then your price per panel expectations, and keep working till you get a system you want. If you piece the panels, the mix and match doesn't work. if you buy one 100w, then they all should be the same rating. etc. etc. to the hook ups to the grid tie, should match the total panels you are adding together, via series or parallel, how many batteries. etc. etc.

They have both. They have individual power cable and they work off a poe switch.
