what size solar panel is required to run this unit?

They claim it requires 215 watts. Mine is on 6-100 watt Renolgy panels and 6 Trojan deep cycle 12 volt golf cart batteries. It has worked flawlessly night and day with power left over to run multiple 12 volt lights in my house. Tim

It's a combination of solar panel size and the inverters self-contained in the Sentinel unit. The unit can accept 12v at 16amps from solar panels, so the recommended solar panel wattage is at total of 100-120 watts. That amount of power will charge the unit from completely depleted to 100% in approximately 8 hours.

The solar panel kit comes with three 15 watt solar panels. Simply connect your solar panels to your 12 volt DC storage battery, and then use at least a 300 watt power inverter to power your 120 volt AC device.

Can't help on the solar panel. I have used the 12v option off of my house batteries. The unit worked fine

I purchased this after reading the other responses and can confirm. I'm using a single Solarworld 250w panel (24v) with two 6v Sun eXtender batteries (wired for 12v). Works great.

Sorry Louis, I can't help you on the solar component. I didn't set mine up with one. I might be able to help you with other questions.

Most larger, more powerful panels are 24-volt. A good charge controller will automatically step the 24-volt down to a 12-volt battery. I don't know off hand if the HQRP will do it -- it seems to say that it does, but you might want a more expensive controller, a MPPT controller. Also, if you have 150-watt+ solar panel, a 10-amp charge controller is too small, as you probably already know. You'll probably want a 20 or 30 amp.

300 watts of solar panels to charge the batteries and run the pump. 4 group 24 deep cycle should due and a 30 amp charger. also there have been problems with pump and i have one go out after just three months. so you might look at another pump

Depends on the wattage of the load and how long you will run in hours. It will work with a 100W panel fine. You will need a charge controller like the Morningstar SS-20L-12V SunSaver 20 Amp Charge Controller LVD. If you plan on running AC device you will need a little DC to AC inverter as well.

1040 watts at an 80% efficiency factor or about 800 watts at 100% efficiency factor. 800 watts = about 40-45 amps at 12 volts which gives you a safety cushion of 15 amps with the unit. if you are going to run the unit at 24 volts, your inputs would be higher since as voltage rises with solar, your amps are usually cut by a factor of about 30-35% at each voltage increase(12/24/36/48 etc) without knowing what your panels are rated at, i cannot answer the number of panels question. just multiply your panel wattage by number of panels= total wattage. hope this info helps you. i can tell you this tho- i was pumping over 40 amps continuous into the unit when first hooked up and it wasn't even getting warm!. very well made unit/even better that its made in America and buying it supports other fellow Americans.

The unit we purchased has run perfectly for over a year on "solar power"."Solar power" in our case means: 118volt, 60cycle, Modified Sine Wave AC. Sine wave should work also.However; if your AC is square wave, I would suggest more research.

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.

There is one solar panel that is 100 watts. I will ask our warehouse to give me the measurements although it may be a day or two hours before I can get that. I will keep you posted.

the unit can run off of solar ,but can also run for electrical power . and yes the unit comes with instructions

Depends on the wattage. This unit is good for 20amps. It auto switches from 12 to 24 volts so the wattage capacity will change. Remember the E=IXR rule. Voltage=Amp X Watts. Wattage divided by the voltage will give you amperage. 12volt system,,,,, 20a X 12v=240watts of solar panel ,,,,,,,,,,,24volt system,,,,20a X24V=480Watts of solar.

It depends on how many amps you need. The solar panel can only out put a maximum of ~1 amp and 26 volts
