Eric, this is very interesting that the foil (Faraday shield) used in this way would help that situation ! A Faraday shield using aluminum foil will only shield electric fields and not magnetic fields of course so something interesting is going on here.   SO, the foil was not grounded in a

[RE-wrenches] MidNite SOB problem and possible solution

2020-12-16 Thread Eric Smiley
Season's Greetings Wrenches We have been attempting to use MidNite SOB's with Sol-Ark inverters this year. In Canada we only need one SOB per string since our Code requires Rapid Shutdown for PV source or output circuits more than 1 meter from the array. However, not all the SOB's were closing th

2020-12-16 Thread Dave Tedeyan
So as you all expected, it was definitely the generator. A combination of reducing the charge rate from the inverter and also not opening the choke all the way helped get a consistently barely acceptable frequency for the inverter to accept it. Without those changes, the frequency was mostly around

Often just adjusting the throttle screw is enough to get these low quality generators back into the spec that the inverter will accept. I expect you will find it well below 60 Hz and 240V (or 120V) when loaded heavily. Many people never do any maintenance so don't be surprised if the air-filter i

Hi All I know this was discussed not too long ago but I can’t find the thread. I have someone looking to replace a 25 yr old March 809 24vac unit. He runs it off of grid power via a small transformer. Thoughts on replacement or the link info. Thanks Jay ___

Wrenches You may have answered you question here, "crappy genny" if the voltage or the freq is to far out or just very dirty AC, the inverter will as you discribed, keep attempting to connect but due to one of the issues can't maintain a connection. Jerry NABCEP Inspector On Tue, Dec 15, 2020, 10:

I can second that it is probably the generator And a 4K generator does not have an off a lot of headroom to charge batteries as well as carry the loads in the house Put a fast reacting meter on it and see what the voltage is as the generator goes up and down charging and not charging I have pl
