On the 250 watt panel the m250 inverter is not needed? Will the panel be more efficient with the m215

For the money go with the M250 IF you are in the southern states, south facing roof where you panel will be producing more power. If not then take the M215

Buy the 215, when you consider the efficiency rating on both invertors and your panel the 215 makes the most sense.

215 will do just fine - i use the 215 on 275W panels (you never reach the advertised numbers anyway). I get 14 kWh out of 11 275W panels with M215 inverters at the tropic of Cancer

It's not more efficient. The panels only put out 250 watts when new from factory under ideal conditions. You can use the 215 with that panel. You might lose out out on a few watts here and there but I don't think the price difference warrants the reward. Just make sure you get the correct connectors to match your panel. I.e. mc4 vs tyco etc.

Hi Stephen!The M215 is sufficient for 250W panels. 270/280W panels and higher, paired with the M215, will result in some clipping during peak production. The M215 is the right size microinverter for your panels. See this white paper for more information (from Enphase):https://www.google.com/url?q=http://enphase.com/global/files/Enphase_White_Paper_Module_Rightsizing.pdf&sa;=U&ei;=7d8VVeafD9KtogTfjoLgBA&ved;=0CAsQFjAA&usg;=AFQjCNH7IlCJnDlOeEMoEkcQb3QOxBRU8w

Depends on your requirements and application. Charge controller, AGM batteries, mounting hardware, M4 connectors and cable and if you want to convert the dc from the batteries into 120 v -- you will need the properly sized inverter.

The output power will be nearly the same as the input power. If your panels are connected in parallel and in full sun light produce 150 watts you should get slightley less output. The grid tie inverter will match the voltage & frequency of your homes power. Make sure the panel voltage is in the range of the power inverters input voltage specs.

Dear Johnny, enphase doesnt makes an inverter for a 500w solar panel. But some other manufacturers do.

Check those specs again... where did you get 15amp from? 115v x 15amp = 1725watts. A 50w panel will not power a 1725watt appliance. Your best bet is to buy a Kill-a-Watt meter from amazon. That will provide you with accurate usage specs.

I don't have that inverter I have the sunforce 1000 watt invertet and it is excellent

You would still want to use a star washer to penetrate the anodized aluminum exterior of both surfaces for bonding between the microinverter and rail. Check with your local AHJ however, since some have not yet approved the integrated ground feature. Grounding the M250 as you would have the M215 (3rd gen) would be going above and beyond the requirements of most jurisdictions.

Yes, I use that size panel too, inverter works good. Any panel voltage should not exceed 60 volts, watts should be well under 600 watts, so no more than 2 of those panels

I haven't hooked mine up yet, but my understanding is that if you run your panel(s) through a voltage regulator to the batteries and hook up the inverter to the batteries. The panel itself will not run an inverter.

It comes with 1 small 40 watt panel. There is no DC outlet. The inverter is not pure sine wave.

No. It is a good inverter though. Some inexpensive inverters will use a lot of energy even if they have no load on them. This one doesn't. Very important when running something that cycles on and off like a refrigerator.

My panel is 50W, and this controller could handle more. It would make sense to me to wire them in parallel to keep the voltage around 12-14V and double the wattage.

Shouldn't be a problem. The only thing I didn't like about inverter was the GFI plug.

The grid tie hooks directly to solar panels, you do not want to go through a charge controller nor do you want to hook to a battery bank. Using this small inverter I am assuming you have a twelve volt system, make sure you do not exceed the 250 wattage or you will fry the inverter For a little more money you can get a 500 or 600 watt inverter, I have 6 600 watt inverters that have been working great for over a year. I have 3 185 watt panels for a total of 545 watts on each 600 watt inverter, It is best to stay a little under what the inverter can handle

Sorry the grid tie you have is not an excess power unit (my system is a hybrid). You only need toconnect panel to the grid tie inverter. You will also have to make sure that the power company is okay with the micro system.

You should look at running 2 - possible 3 100 watt panels, if an upgrade for future look at 10 gauge panel wire, it seems your running 12 volt, but your inverter and charger will depend. I've got a 40 amp 12/24 charger but batteries will run at 12 bought in a kit with 6 100 watt panels but told to only run 5 as my 60 amp also takes 1600 watts if at 24, but running at 12 so 800 watts mix up and I was sent a 12 both are mppt, you can probably run 5-6 100 watts if you have 2/ 25 amps combined, if not mppt they will keep charging but at a lower rate will destroy your batteries if not in use all the time, go with 10 gauge wire you will be happier.
