would I need two or four of these batteries to work with house hold appliances. Type of watt panel, control charger and Inverter. Portablebackup Proj.

Well the answer tothat questing really depends on what house hold appliances you plan to use. you might be able to power a radio/blender on these batteries but you will not be able to power a stove or a fridge/microwave from them. If you are looking for batteries to power full use appliances with you will need to look at deep cycle full size batteries. As to the pannel size that depends on how much run time you need and how much sun light your area rreceives. The inverter size should be based on the highest watt useage item you want to run. Charge controller would depend on size of pannel and desire to add pannels. There are many web sites that will provide more detailed information. Just Google it.

Yes sir. You can Google different sites to find a watt calculator step one. When you figure out how many watts you need to run the equipment you want to run you can figure out how many watts of solar panels you need. You can also find site's that will help you with your battery bank as well. If you decide to go off grid? Grid tied is another story and I can't help with that. When you put that all together you'll know what type of inverter you'll need to supply your house, cabin, RV etc. If you do your homework you'll find that solar is a very good choice.. Good luck. Do your HOME WORK first!!

Hi Karen, I think your question is back to front......but I may be wrong. The batteries should be rigged up to supply the inverter with + 12 V Direct Current for the inverter to supply nominal 120 V Alternative Current......The inverter will take power from the batteries and if the batteries themselves are not supplied with power [from solar panels, an alternator or charger] the inverter will eventually take the batteries down to about 10.5 V DC whilst still delivering the nominal 120 V AC. Which is not good for the batteries. I hope this helps.......best wishes....Jack.

I believe the battery will do the job. I live off the grid and I am using two of these batteries to power a solar powered chest freezer and a solar powered water pump, full time on my small ranch. Even during the recent winter storms,(no sun), we have plenty of power for all our watering needs, for home and livestock. Patrick

Not a chance, this inverter is for small appliances. Lamps, hand drill, charging battery's , radios.

It depends on how long you intend to run the appliance. Frig. 3-4amps @ 120V = 420 watts. Divide by 12 = 35amps per hour. Typical large battery has 150 amp hour capacity but not at that rate and not fully discharging. Regular batteries are cheaper and you will only discharge to about 11.5 volts. That is why most residential system use line inverters and sell back to the utility. My starting point would be 10 if I was seriously wanting to benefit from a generator / battery backup on these appliances.. A couple of batteries could take all the charge a 100 watt panel could produce for days. Store it, use it or lose it because you can't afford your design intentions here.

Yes. We had no problem with using regular house hold current. Just plug it into wall socket and have it. It will rumble your butt off!

inverter power supply should be based on what you need to run in the storage room. The wattage load it will handle. I can tell you that the battery can run a trolling motor for over 4 hours and still have power left. I think I would check the amperage draw of the inverter large enough for your need and divide into the amp hour rating of your battery to give you a idea of how long the battery will last.

I agree with most all said here before. Get 2 12v batteries in series = 24v, or 4 6v and hook up in series but controller is best way to go to match your solar panel. Most quality solar panels will charge 12v and 24v. Get a volt meter and check it out as you go. A fuse is a must. Good luck

The HQRP charge controller will work with your 100 watt panel. Whether or not your entire "system" is right for your needs depends on your loads. If you plan on running a fridge, TV, radio, lots of lights, electric heater, etc., it ain't gonna happen.

I agree with the other posts . You need Deep cycle batteries but you also can find power inverted made to accomplish this task the only question being capacity wattage and if it has pure sine wave out put as long as your load isn't more than what the inver can provide and battery has enough capacity & is of correct type then you should be fine . Never however modify or tinker with UPS and modify it beyond what the design say .

I currently have a small system (4-250 watt panels and a battery bank of 20-12 volt batteries), which I use primarily for back-up in case of a power outage. My recommendations are: first, consider how you are going to use the system: total energy supply with the grid (i.e. power company) as a back-up; operate some of your house on solar, with any excess being fed into the grid; back-up in case of power outages. You also need a clear view of the southern sky, since the sun is always to the south in the U.S. Panels mounted on the roof of the house require a licensed contractor, and only the part of the roof that faces south is suitable. Where you live is also important. Solar does not work well on cloudy days and in the winter when the days are short and the sun is low on the horizon. This is especially true in northern climates. Cooling is very difficult, since air conditioners/heat pumps typically run on 220 volt/2 phase electric power, which is hard to produce with solar power. I suggest you find and consult with a qualified solar installer. Typically you need the solar panels, a large battery bank to store the electricity produced by the panels, inverters, which convert the DC to AC for use in the house, plus the appropriate wiring into the house circuits, etc.

no you can't...you have to get a MPPT charger controller..the panels puts out up to 20 volt of Dc.. and the controller charges a 12 volt battery then you need a inverter that hooks up to the battery to convert to 120 volts then you can hook up appliance unless The appliances is 12v then you don't need the inverter.....

There should be battery back-up in parallel with solar panels to provide adequate current for operation. If there is a 4000 watt rating for the inverter, the battery should have 340A available for the inverter.

Totally dependent on how much reserve your seeking. As always...you'll need a charge controller with the batteries to prevent damage to them from overcharging and an inverter depending on your actual power need. Amazon has a few good books on Solar, you may want to pick one up. I have 5 of these in series and no batteries, at the moment leveraged only for operating my solar well pump.

You can use these to power well pump etc but you really will need a good battery bank with good quality batteries and the most important part of your system will be the power inverter. You will have to get a good quality pure sign-wave inverter to use for house hold appliances and water pump. The panels are excellent and the price is good but everything else that you need to add gets a lot more expensive. Batteries are around 200 each, inverter is around 1000+ etc.Hope this helps a bit, you can research off the grid hunt camp power systems to find out more information.

Charger? I have 245 watt of panels to a BZ MPPT 250 solar Controller, to three batteries in series.To inverter.
