Glad to hear you've got that array better anchored.

Last night was probably a worst case scenario. The ground was as soft as it usually ever gets, the array is still at the winter angle catching the most wind, and we had wind exceeding 60 mph.
It was still dark when I left this morning, but it looked like it stayed put. I'll look closer when I get home to see if it was pulling at it anchors. |

Good to know it didn't move on you!
Also, I'm liking the weekly updates. Its interesting to see the fairly wild fluctuation in power generation. I wonder if in summer if that will tame down? |

"backfeeding the grid."

Trying to work with the power co. is something I don't have much interest in doing. However, I'm interested in the Enphase Micro-Inverters, but since they are not made for off-grid operation, I'm a bit reluctant to start buying them. I wonder if one could fool the Enphase units into thinking they were on the grid, by using a 220vac power inverter?? And then use the power on isolated house circuits that require power 24-7.?. |

I remember one time when a fuse blew out on a drier. No heat at all, but the motor kept turning. My shirts were getting a ride, but stayed wet.. It was a 115V motor.. It sure seems like that neutral is going to be used to pass current whenever a load is placed between one of the hot sides and the neutral.. ------ "direction the power is flowing" IIRC, the specs on the inverters say they use a VERY small amount of power when the sun isn't out. You may not even be able to get a reading on your Kill-a-Watt. Cheers, Rich PS: I do Electronics, I'm not an Electrician. |

I have seen nightime increments from time to time from standby loss. Most likely it was close to rounding to the next digit before night and it used enough standby to increment it. I don't count these nightime increments in my production #s I post. Last edited by jwxr7; 07-15-10 at 06:29 AM.. |

Doesn't look too bad, but what happened on Wednesday?

"never measured any current in the neutral"
Re: "never measured any current in the neutral".
If you are only using your inverter to supply 230V Only devices, I can see how that could happen. But, if you plug in a 120V appliance, it's not going to be across the 230 lines, but one side of the 230 and the neutral.. So, if your 120V 60W lamp comes on, it's getting it's power from 120V & Neutral. What is your load?? Are you sending the inverter output to a 230V battery charger?? |

It's grid tied. The grid is the load.
