i have 320 watt panel, 2 deep cycle battery 12v-55 Ah,40A 12V/24V MPPT Solar Panel Charge Control...

i have 320 watt panel, 2 deep cycle battery 12v-55 Ah,40A 12V/24V MPPT Solar Panel Charge Controller, is that ok for this inverter to run my pond pump is 1200 watt 24/24 Thanks loi
Asked by: van
I would strongly recommend that you use your solar power system for running the necessities you really need , Such as lighting in your home , I would run the pond pump on city power , But you need to monitor the charge on your batteries and allow them to reach full charge , My buddy has a solar/wind turbine power system and what he does is he'll use the solar/wind turbine system to run lights and other necessities , Then he'll switch over to city power when the batteries run low to allow the batteries to fully charge , The available run time for the solar power system depends on how much power you're getting from the solar panels , The rate of charge for the batteries and how much power you're drawing from the inverter , When you're running continuous power on your solar power system , You must monitor the charge on your batteries and don't let them discharge more than 80% , Or the batteries won't hold a full charge after charging , You need to cycle you batteries periodically to get the maximum life out of the batteries , You can run the pond pump on the solar power system as long as you monitor the charge on your batteries but don't let them run low to where the inverter shuts down or the charge drops below 80% , On a sunny day , Allow the batteries to fully charge and on another sunny day , run the pond pump and time It while monitoring the charging on the batteries , This method will give you an idea how much run time you'll have to run the pond pump , Do the same method on cloudy days so you'll know what run times you get on sunny days and cloudy days , Be absolutely sure you check the water level in the batteries and use DISTILLED WATER ONLY !! Using tap water or bottled water will ruin your batteries because tap and bottled water contain mineral deposits which will ruin a battery , Also I strongly recommend that you use a true sine wave inverter Because modified sine wave inverters will damage certain equipment , Such as cordless power tool chargers and sensitive electronics , So to get the maximum benefit from your solar power system is to get a true sine wave inverter , It's Definitely worth the extra money and is safe for all equipment , Because true sine wave is clean power , The same power in your home DANGER ,!!! Regular lead/acid batteries MUST be outside , Batteries produce hydrogen gas when charging or discharging and is highly explosive and has no odor , Always wear full safety goggles , Rubber gloves and other protective clothing , Batteries contain sulfuric acid and will cause severe burns on contact and cause severe eye injury and possible blindness , NEVER smoke or allow any open flame or sparks nearby and be extremely careful not to short circuit the terminals when checking the connections , Good Luck with your solar power system and ALWAYS PUT SAFETY FIRST !!!

Can all three power outlets be ganged together for max amp output?

Can all three power outlets be ganged together for max amp output?
Asked by: Dick
All the receptacles on the unit are connected together , So no paralleling is needed , Just one receptacle will provide the full 1500 watts of power but if you use both receptacles , The total load must not exceed 1500 watts , Keep this in mind , When sizing an inverter , The inverter should be at least 1 1/2 times greater wattage output than the wattage the appliance draws , For example , If the appliance draws 1000 watts , You should use a 1500 watt inverter , The residual wattage available will prolong the life of the unit , Also , For every 100 watts of 120 volt AC power from the inverter , You will need at least 10 amps of battery power , To get the maximum 1500 watts of power , You will need at least 150 amps of battery power , Two large deep cycle batteries wired in parallel to run this inverter is strongly recommend , DO NOT use this inverter on a regular car battery , It will drain a car battery very quickly and ruin it , Two or more large deep cycle batteries wired in parallel is strongly recommend , The more batteries wired in parallel , The more available battery power

Can sunray 1500 run a 16cu ft refrigerator without overheat

Asked by: Kip
You need to look at the information nameplate or sticker on the refrigerator​ , It will tell you how many amps it draws , Multiply the volts times amps to get the watts , if it comes out to less than 1500 watts , Then it'll be OK but you will need a large bank of batteries wired in parallel to get enough run time for the refrigerator , And it would be very expensive to get enough batteries to run a refrigerator , During a power outage , A portable generator would be a much better alternative Compared to the cost of buying enough batteries to run a refrigerator off a power Inverter because to get the maximum 1500 watts of power , You will need at least 150 amps of battery power , So you will end up with a short run time with batteries compared to a portable generator , Anytime you need power for an extended period of time , Such as for running a refrigerator , A portable generator is the best alternative during a power outage , A power inverter is good for when you need power for short periods of time and the true sine wave inverter is strongly recommend because modified sine wave inverters will damage certain equipment , Such as cordless power tool chargers and sensitive electronics

Sunray 1500 Pure Sine Wave Intelligent DC to AC Inverter (12-Volt) is rated 3.6 out of 5 by 10.
Rated 5 out of 5 by from Ramsond 1500 pure sine wave inverter I run a refrigerator & a 100 watt bulb at the same time constantly on this inverter no probs awesome .

Rated 4 out of 5 by from This is a recent purchase I got this pure sine wave inverter primarily to power my pellet stove. Living in rural Vermont means there will be times in the long Winter when line power is out. The pellet stove needs power to run combustion air and distribution blowers. Since the stove draws about 1.5 amps, this inverter has no trouble providing the juice required. I did follow the recommendation on wire gauge from the battery pack to the inverter to reduce line loss, which can be very significant if improperly gauged wire is used. The battery bank is 2 6 volt 220 AH golf cart batteries wired in series with a single 12 volt 112 AH deep cycle marine battery wired in parallel for 12 volts and 332 AH. 2 45 watt solar panel arrays charge the batteries through a 10 amp solar charge controller. i did a bit of research and believe this inverter gives me the biggest bang for the buck. At some point, I'll need a bigger soar panel array, larger inverter AND battery bank to run the household off-grid. But as a first foray into off-grid power, this gives me lots of experience.

Rated 5 out of 5 by from So far, a great purchase------- I have this little inverter installed at my cabin, and thus far it has performed above my expectations. Thus far, it has been very lightly loaded, and only in the evenings, but I have yet to see the cooling fans kick on. My wife uses a CPAP, and thanks to a couple of deep cycle RV-Marine batteries, I only see about a 2/10 voltage drop over night. I'm sure that is not only due to the quality of the battery installation, but also due to the low power demands of the inverter itself. My only complaint woud be that because I ordered the unit on line, I could see no way to ask for the 10% "Combat Veteran" discount that I always receive by shopping in store, by showing a copy of my DD-214.

Rated 1 out of 5 by from RUN Very poor service response. Came out of the box BAD, called service support and they said it was bad fans and that they will send me new ones and they will be here on Monday! So after not receiving them I called again, 3 days later they arrive. Guess what didn't fix the problem? I decided it was time to send the pile of junk back to them to fix, but all no, have your credit card handy, they are going to charge you even under warranty to repair it, parts and labor are free, cough. So why throw good money after bad? Will be buying something else to replace it.

Rated 2 out of 5 by from Good product for the price. Recommend putting a 25amp fuse on both neg and positive leads from battery to double the protection of shorts. The internal 30 amp fuse failed to blow as the OCD and shorted the internal control board. I was attempting to use a 12 amp circular saw when the short occurred. Thanks to Home Depot return policy I was able to return the product hassle free. On that note I tried to contact the manufacture but no response.

Rated 5 out of 5 by from Works Great! Bought this inverter to power a CPAP machine in a big truck. Works great and has no problem running my microwave, etc...

Rated 1 out of 5 by from Buyer beware! This product does not work as advertised even after paying to send it back to the manufacturer for repairs and receiving it back. The unit will not handle anywhere near 1,500 watts. Even running our 32" LED TV causes it to cause the TV to reboot every 10-15 minutes. It was installed by my RV dealer because I wanted to make sure it was installed properly. This has basically been a waste of money and now I will have to buy a different inverter. Very disappointing. DO NOT BUY
