How many of these would I need for a 500 sq ft cabin? I would use a wood stove for heat so the solar power would only be for a few appliances/lights.

I think it really depends on several factors. Are you going with 12V system or 24V system. I am using the solar panel for 12v system on my RV in remote areas and have an inverter to run few 110v devices. Typically I get 10 amps during the day in the summer and less in the winter months. You can get more with better controller. With 4 storage batteries it is adequate. If I was in a cabin I would try to maximize on power capable on this panel and build a 24v system and use an inverter to supply 110v for in the cabin. With 24v system, because this panel output is 37v you get more power. It also depends on what appliances you have in mind. In general you really can't run any appliances that use lot of power like large fans for long. But you learn to convert everything to low energy use devices. I have converted all the lights to LEDs. Prior to conversion regular lights would drain the batteries in hours. But with LEDs it takes weeks. I think with enough storage batteries one panel is adequate, but if you spend lot of time in the cabin in the winter months, I would install 2 or more. In general this large 37v panel is better buy than several 18v panels. Hope that helps.

It will depend on what type and wattage your appliances/lights are going to be.

This is the smallest unit that we make and is generally used for small lights and cell phones, lap top etc. in order to run a heat lamp for longer periods of time is to have the solar power and the batter power equal the power of the heat lamp x the number of hours you need the lamp to run. An example if you had a 500 watt heat lamp you will need 500X 12(volts) = 60 amps per hour. That equals 8 (110) amp batteries and 800 watts of solar power. We make this size unit quite often that typically cost between $2,500 to $3,500. I hope this answer helps you. Don OGSolar Power

The model is SG-TTW-12HC-26, it should heat up 400 ~ 700 sq.ft. However, it depends on various factors, like the insulation of the room, whether it is facing direct sunlight and so on.

That will depend on how many you are using and how they are configured. Assuming you are using 1 (or any number in parallel to obtain more amperage) any 12 volt trickle charger would be sufficient. I use both a solar and an electric trickle charger myself. Another thing to consider is how often you expect to use and/or drain them. If you are using them for emergency back up, you will needs a slower charger than if you are planning to use them constantly. If these are going in a vehicle, any 2-10 amp charger will do.

All heters are the same really. 1500 watts is 5000 BTUs and it doesn't matter much after that. 13x14 worked fine for me but it depends on house insulation, and outside temperature. It was also supplemental, as the centeral heater was holding the rest of the house at 63.

You can add more batteries and panels to this system. We have a 5000 watt 300ah system with three 100 watt panels for $1899.

This would be way overkill for a 13 watt solar panel. One 13 watt panel would not even need a regulator while camping as your use would always exceed your input. If you were to store the camping unit without using any of the generated power it may eventually overcharge the battery slightly, though no damage would occur to the battery only slight loss of water in the cells which should be checked regularly anyway. There are usually enough parasitic loads (smoke detectors, clocks, radio memories, etc.) to compensate for the slight overcharging though.

well you may find you need more than 200 watt transformer. i got a 500 and run all my U.S. stuff on it. ie TV, laptop.. hard drives :)... ps stay away from the one with the usb port. its junk.....

This is primarily a 12vdc device. You would need to set up batteries with an inverter to run your AC operated devices, and you will most likley need two or three panels to keep up with the demand.The batteries would need to be enough to run your heat lights all night I am guessing. Knowing (calculating) what your power demand is will be key to proper setup. That will tell you the number and capacity of batteries/inverter you will need and the charging demand you will need taking into account cloudy overcast skies (winter weather, etc..) when a solar panel is not as efficient.

Probably 3 space heaters would be too much load for this generator. It depends on how many watts each heater requires. The small heater I have is 1500 watts, so three of them would be 4500 watts, too much for this machine. You would need to consider a more powerful generator.

2 would be fine. Lots of power here. Back wall pointed out. I have 8 of these and they are THE Best you'll find anywhere. All are over 5 years old. I use them everyday. Not a problem....ever.

"a lot" is a very subject phrase. the full size uses 130 watts max. it's a heck of a lot less costly than heating the whole room.

Do lots more research before making any purchase. You saying 750KWH/month says to me (750 / 30) 25KWh/day. If that were solar panels, that would be about 12,500 Watts of solar panels in a 2 sun/hour day area. Somehow I expect you mean something else, tho some homes use that.

1st 1500W for a house is small. Refrigerator and small coffee pot, the fuse type listed 200a is needed, but seriously 1500 for house... I have 2 2500's on my boat

It depends on where you live and how much sun you get. Based on 140W 24/7 the 300W "kit" won't be enough. That doesn't mean you couldn't do it with more panels. Just don't buy a "kit". That comes with a dedicated charger for the wattage the kit comes with. Check on line or with someone who can give you the calculations you will need for wattage and but individual panels and then size a charger for your needs. I had to do the same. The panels that come with the kit are top notch and can be bought by themselves.

Depends on what you are going to use it for. If you are going to use your Setup for Emergency Lights, Battery Chargers, Small Appliances the Inverter you use will draw harder off of the battery the more devices you use. I use one 50 watt Solar Panel, Charge Controller, Inverter and two of these Deepcycle 35aH batteries for power outages, emergencies etc. A Small Solar Panel will just trickle charge the battery and you won't be able to use it for powering much before it drops down to the minimal low voltage. A 50 watt Solar Panel is probably a good starting point, then go from there as to what you need to meet your needs. Depends on what you are going to use it for.

Forget @ using any of these units for heat. Look up an amp meter chart etc., compare what you heater will draw and divide the 1000 W and you will see the heater won't run for half an hour...a hair dryer will kill it quickly. This is strictly for lights, etc. Save it for medical equipment etc. in extended outages... maybe an occasional microwave use , etc. Even a computer charge will run it down. Be Careful how you use it. Also you can save a lot of power by using only lamps with the new twisted looking lamp bulbs .. Thet use @ 1/3 the power. Save the power for a quick sump pump need nothing continuous except lights. For heat, look into a small wall natural gas heater ( if you have gas heat ) @ $300. will heat 1000 sq feet quite well. Get a warm coat and blankets if the power may be out for days or you will be w/o lights too. Otherwise geta generator..note most condos won't allow them
