Power meter goes backwards with 300 watts of solar panels and grid tie inverter

[sergiogsx79]

please could you tell me what inverter do you recommend? I am about to get a 170W panel but hopefully in the future i will get a second one. thanks, great video

@sergiogsx79 Thanks.I think the brand is 'power jack'.There all over Ebay fairly cheap & just plug into a regular power outlet. I have,a 300w 12volt,& a 600w 24 volt.They seem to be ok,just dont run them at there rated wattage.I only ever put 2/3 or less of their rated watts through em. So for ur panel i would suggest a 300watt,but because you want to add a panel,u have the option of 2x300w inverters,or just get one 600w inverter(if u want to put all your eggs in one basket). i hope that helped

@djpaulk found them on ebay !! thank you so much! I was so excited to see what I could do with me new solar panel, but right now I am facing a possible truth. I've read that it might be illigal to pump electricity into the grid in Spain?!?! I also read that its fake that a power meter will go backwards when pumping electricity as you do, that normally power meters have a system to avoid it going backwards. ..next message

@djpaulk So I dont know what to do. At least I would like to know if I can build your setup and pump those 180W to the grid and as I am always using more that 500W at home, then just use them so the power meter goes a bit slower. do you think this is possible? Thanks for your answer and once again, great video !

[djpaulk]

@sergiogsx79 Yes,thats pretty much what i do, it does only slow the meter while power is being used.I turned every power consuming device off in my house,including the fridge,before i took this vid,for a demo.But while im out at work and everything is off,its happy days :) Nothing FAKE about it. I sometimes make mistakes,but i do not lie..Believe me,it works!!!! spose it may depend on your meter type?i dont know about digital meters,but works on these.. Thanks again and check my other vids

Awesome demo there

Thanks for the video.

I love to get hold of one of those clock dial Email meters as I collect old kWh meters

That's a facinating demonstration. I didn't realize hair dryers used that much energy.

[djpaulk]

@tsx1561 Yeah,i just went and read the label on the hair dryer says; 1700-1800 watts.Thats about as much as a small electric heater :o
