6 rooms will have 1 light in each. they are 3.5 watts not 4.5 as I stated before. They wont be all on at the same time. just as needed. I would say maybe at the most of 2 on at night. not all night just as needed. Im gonna read the white paper now. Im tring to be more green. Next im working on is hot water from my wood stove.via a coil to my water storage and 12v heater elements. ran into a wall on temp switches that can handle 12v You will be fine with the system you have right now.. No need for more panels.. |

See I revert back to my {KISS} solar system and that is why they put % displays on CC! No they put it there for people to ask why isn't it at 100% all the time when it's full... Engineers put it there... They always like to over thing things.. |

Battery charger says 100% at 13.2v. I'll leave it on a bit. It has a tender in it. Gonna change panel's around to series over the weekend as its 10:30 pm. dont feel like climbing up on roof and playing with wire as of now.If i add 2 more 100 watt panels a mppt 40a controller should work? I should have most of the inline fuses that I need,As i work at an auto Repair/used car lot and get lots of them from car stereo systems left behind.

I had no drop in voltage after 50' was 23.70 at panel and at the other end of the 50' run was also 23.70v only dropped at the connection when i put the wires into the cc.

Yes sir with a 40a CC you can run 4 panels, depending on the CC you can go up to 8.. |

LOL " I did check battery's before I hooked everything up.They were full and and had a good load test of about 6 sec's." did ya read that, he thinks his batteries are full |

When connected the controller forces the panel to operate at max power pt of 18v or what ever it happens to be. It changes all the time and the controller is supposed to 'scan' the panels from time to time and adjust. Internally the controller transforms the 18v to batt voltage to charge. |

A tender is not much of a charger for 200ah bank. if you do not have another charger let the sun charge them up, I hope you find a sunny day where you can look at the monitor every hr or so and see what batt voltage does as it climbs to 14.?v, stays there for 2 or more hrs and then goes into float mode of 13.?v.
On the roof will get hot in the spring/summer/fall and why I would go with higher input voltage ie series for 12v panels, if ya add 2 more ya might consider having 2 strings of 2 in series.

Yea that's why I asked him what CC did he buy... |
