YES I DECIDED TO TRY IT KNOWING NOTHING ABOUT SOLOR. IFOUND THAT IT WORKS EX. AS DISCRIBED. IT KEEPS 2 12V BATTERYS CHARGED ALL DAY TIED INTO AN INVERTER TO 110V AC FOR LIGHTING. HAVE HAD 0 PROBLEMS WITH IT TOOK ABOUT 1 HR TO READ AND INSTALL.WILL BE BUYING ANOTHER IN THE NEAR FUTURE TO ADD TO FOR RUNNING SMALL 110V POWER TOOL’S DURING THE DAY AND LIGHTS AT NIGHT FROM BATTERYS.LATER ON WITH ENOUGH PANELS I PLAN TO TIE TO GRID.IF I KNOW IT WAS SO EASY I WOULD HAVE DONE IT A LONG TIME AGO. HAS ALL THE INFORMATION HOW TO DO. EDPAS.

Was on my camper for 3 years. Never charged the battery, even though it showed charging. Probably all the current was going to power the charging LED bulb. Finally ripped it off and got a Monocrystalline panel. Works great. I dont think this thing could charge a 1.5V AA battery.

There is typo on the description of the product it says “600-Watt MSW inverter” but is really a 400 Watt you can see on the images of the product parts…
So far I was able to connect for 1.5 hours to my 12 V battery from my motor-cycle and was able to charge it enough so that I could start my motor-cycle and note that it was totally dead before charging.
Good product but would like to see a place that could tell me about the different types of batteries and other applications that can be done with this system with more implementation details.
BTW I bought this product at Costco in Guadalajara…

I bought this from a different retailer but so far so good, its creates good voltage even in non-full sunny areas compared to the more compact cystaline panals.
I like that it came with everyhing needed, except a storage battery, to get strted
-The specs are as my photo shows.
—-You must do a little research and a tad bit of math to see what you can power and for how long.
I calculated a couple things as i will eventually be using these on my truck. But for now there on my patio.
Im by far a beginner in his stuff but im fairly certain this is correct.
So… solar panals total does about 4 amps per hour
Example…
12v walmart car fan 10watts so .8 amps
So it uses .8 amps an hour, if i have it running while we sleep, say 6 hours thats .8×6
Is 4.8,we will say 5 amp hour battery would be dead( actually ruined because lead acid batterys cant discharge to below 50%) after that time. So we need the battery to have at least 12 amphours like this 1… https://www.amazon.com/ExpertPower-EXP12120-Volt-Rechargeable-battery/dp/B00A82A2ZS/ref=sr_1_1?ie=UTF8&qid=1474230806&sr=8-1&keywords=12+amp+hour+battery
So if u have that battery and that walmart fan and the panals, u can run that fan for 6 hours and have the battery be charged in around 1.5 hours .
If the panals charge at 4 amps an hour, and u have 8 hours of light u can theoretically charge 32amp hour battery in that 1day. 4 amp hours times 8 hours
1more: my ipad 2 needs 2.1a@5v to charge, the ipad charger converts the 12v to 5v, so i dont need to worry about that.
So if i want to use my ipad at night when theres no sun.
For 5 hours, the ipad will use 2.1×5= 10.5 amps
So if the lead battery that was charged during the day (by the solar panals) had 22 amp hour rating we would be fine.
Lets say i wanted to use the ipad all night for 10 hours. That would use up 10x 2.1= 21amp hours of power but remember we need twice the sized battery, so we need a 42amp hour battery ,so the battery dosnt discharge too low.
We could do that, but we already said the panals can only possibly charge @ 32 amp hour battery fully in 1 day, so if we wait a full day and another couple hours the next day, the battery will be fully charged again, and we can again use the ipad for 10 hours at night.

I bought this for usage with my RV Trailer. Thought it would be great to keep the battery (12 v deep cycle) charged during up during the day so could not run the generator so often.
Solar Panel; It could not keep a single (car size) 12v battery charged with minmal draw of current, In case it was tthe battery that could not hold a charge, I tried a brand new battery.. same thing. Battery never reached a full charge. The unit was used (trialed) at a camp site on a beach in direct unobstructed sunlight 12+ hours per day. I gave it the fair shake.. using it for 3 weeks.
Power Inverter; With battey at a full charge (using my generator to ensure full charge) the power inverter included with the solar farm could not even power a laptop computer without the overload alarm going off on the inverter. By comparison, I have a power inverter that I bough at Walmart, and that specs say is the same wattage, and that runs the same laptop with no issues.
So, as excited as I was about this product, to get off the generator at campsites, it fell far short of the mark. I returned it for a refund.
Perhaps it could keep motorcycle batteries charged, or run a trickle charger on a 12v battery (to keep them from going dead over the winter), but for over $200, that is a pretty expensive use that would never pay for itself.
