How many watts does this pull? I am on off-grid solar and have to be very aware of watts pulled from the battery bank.

My husband says 25 watts. He is going to make 4 plug ins for me. Hope that this helps.

According to my kill-a-watt, it is drawing 24 watts. Only measured for a minute or so.

This device doesn`t support the batterys.Your Charge controller & solar panels determon what charge is in your batterys. The amount of amps drawn from your battery to run this device is determoned by how much power your load is drawing from the inverter.I have 30 deep cycle marine batterys supplying power to my 2500 watt inverter & I run two 1000 watt electric heaters, my frig. and house lights when I have a good supply of sunlight charging my batterys at 14.3 volts from three 40 amp charge controllers.I have at times seen this inverter draw my batterys down on a very cloudy day to 9.6 volts and still put out 115 volts.Any lower battery voltage and the inverter will shut down, but will come back on automatically as soon as the battery voltage gets built back high enough to run the inverter.

This is a very nice solar panel that is mounted on a somewhat flexible metal sheet. I produces about 16v dc at the contacts in Florida sun (rated at 12v for a 12v battery), but I use a solar controller so it won't overcharge my battery. I have it hooked to a 12v trolling motor deep cycle battery on a small boat. I have not had to externally charge the battery since attaching the solar panel, and that gives me a few hours per week of power.

Rommel, I agree with Tim. It depends on what you are going to use the stored power for. For example, on average you will charge the batteries 10A for six hours or 60aH. If you are running a water pump that pulls 5A for 15min every hour you would need approximately 30Ah to run 24/7. In this case one battery is more than sufficient. In my case I run LED worklights and cameras. I pull about 10A for 8 to 10 hours which adds up to approximately 100Ah per day. Taking battery degradation and the fact not every day is 100% sun, we use two batteries. Hope this helps with your scenario.

I run mine from an inverter that is hooked up to batteries that are charged by my solar array. It uses very little power.

Inverter choosing is not only a money matter, it's also about consumption, and potential growth. You 95 watts solar X 5hr, is what we use on an average day harvest. Might run one tv for five or six hours. You loosing the solar charging war. your banking 2760 watts 1380 @ 50 percent harvesting 475 watt and when in full rv use you'll use a lot more than you harvest. Why not just but a couple cigarette lighter 150w or 300w inverters?

The panel does not output 5W like the specs and other reviewers suggest. The integrated *battery pack* outputs 5W, but the panel itself seems to only output in the range of 1W to 1.5W.From the specs directly from the manufacturer, the battery is 2200mah, and it takes the panel 10 hours to charge it. If you work the math out, that means it charges 220mah per hour, which would be 220ma of current @ around 5V (maybe slightly higher?), 5v * .22a = 1.1WJust because the unit has the capability to output at 5W, doesn't mean it can collect power from the sun comparable to a 5W panel.

I'm using the Outback FM80 with 1500 watts, 6 x 250 watt panels using a 24 volt battery bank. You need to decide what battery bank to use? The 24 volt system is recommended. You can call the engineers at Grape with any ? you might have! They are very helpful.

I used this for charging a smaller battery, a motorcycle battery, and discharging into a power inverter for landscape lights at nights. If you are going to maintain the battery without loads then yes I would say. It only produces 10 watts.

watts is just amps x volts so it depends on how many amps you are drawing from the battery

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.

If I understand your question correctly. your requirement is for a 400 watts solar input and if 408 watts of solar input is ok, I am assuming your question is for an off grid system (charging batteries). Question is if your your charge controller can accommodate additional 8 watts of input or ignore this additional watts without damaging any of the equipment. Please check the documentation of your equipment (charge controller) if it will work properly with the additional power provided by the solar panels. Normally additional power provided by the solar panels is ignored, one should make sure that electrical specs are matched with the solar input with the charger such as input voltage 24v panel and 24v charge controller input. Output from the charge controller should be matched with the battery voltage such as 24v solar panel, 24v charger and 24v battery, if different use an MPPT charge controller which can accept higher voltage from the solar panel and charge a lower voltage battery such as 24v panel, MPPT charge controller and 12v battery. Hope I have answered the question.

A good 100 watt solar panel properly aligned to the sun in very bright sunshine will provide about 5 to 6 amps of charge into a 12 volt battery. A commonly used solar storage battery has a capacity of approximately 100 ampere hours (about the capacity of a fairly large "marine" style battery). This battery would require about 12-15 hours of GOOD sunshine to recover from being HALF discharged. This truth is almost always what's left out of the sales pitches for these "plug and play" solar generator systems. Yes, they may have an output of 1000 watts "continuous power"...but the reality is that the storage battery providing that 1000 watts will only last an hour or so. The math is simple. Don't be fooled by vague specifications. ASK QUESTIONS OF THESE SELLERS!!!

Hello. From my understanding and current tests. The higher capacity device will pull 2A. And the lower end device will pull 1A. I have ordered a USB Meter to see if either USB port is designated solely for 2A. So far. The panels put out great power and I am satisfied. I haw changed an iPhone4, iPad mini no retina, lg android, 12000 Mah newtrent power extreme battery bank, 5200 Mah brightech battery bank, and eneloop rechargeable batteries with the eneloop USB charge adapter. All devices function and chare fine. The phones and tablets will read an error of power soure of the panels are not in direct sunlight. It's an easy fix. Just position the panels on the sun again. I highly recommend a external battery bank. This way you store the unused power. No sense in wasting free juice. Hope this helps.

Joe, It seems to be a little more than 40 watts. at 12v it draws 4 -5 amps - 48 to 60 watts. I use a 100 watt solar panel which will do 7+ amps, to charge the trailer batteries and run the frig freezer during the daylight hours. This arrangement has kept my ice cream frozen for four days in Death Valley (90-100) temps without starting the tow vehicle. .

I have had this connected to 2 100 watt panels and four golf cart batteries wired to 24 volts. I have also had it connected to 12 volts on my larger solar system and it works fine although pumps at a slower rate.

I connect to 24v batteries rather than solar panels to get max 300w out. The batteries are solar charged.
