    2 pole transfer switch to isolate AIO/Hybrid all seem so expensive..... (200A)

    Looking at the EG4 15kw, but applies to just about any AIO system or generator input etc. Why are 2 or 3 pole generator transfer switches so damned expensive? I mean, looking at the GE TC10324R -- looks like Home Depot has best price of around $650. But its a nice heavy box with three sets of...

    Overcoming bonded neutral issues in the setting of a GFI protected Ford Lighting 7.4kw inverter.....

    Probably not exactly a "beginner" questions, but seems the generator forum is pretty quiet, and this question involved solar as well. Ford Lightning owners have been challenged using their massive battery pack for input into backup power in settings via transfer switches, as well as using the...

    Help me understand solar panel ratings and when/how I need to acomodate for "over voltage" situations.....

    I am trying to get my head around an Hybrid/AIO system. Looking at the EG4 18k for instance, it uses up to 500v, but can handle up to 600v without damage. OK, seems straight forward enough. I will have a long run for the DC lines back to the AIO, so I want max voltage. Then I look at panel...

    Help me find some good cheap panels...

    I have quite a bit more roof space than I have need. So I don't need panels that have particularly high wattage (though of course one can save on racking with less panels). My roofs are all steel and really optimal in locations, so I 'd rather go that route. Large roofs on large sheds at a...

    Help me make sure I understand running DC high voltage wires buried in conduit back to inverter from remote (125ft) array

    I am contemplating putting some underground wires to get additional panels on a shed that would be around 125ft away from my inverter. This was suggested in a couple other threads. Another suggestion was to run the wires in conduit. Allowing for upgrades in the future, if need be. I am...

    West facing panel idea?

    I have a perfect south facing roof. But its over 400 feet from the main loads. I would potentially need 200A service in the distant shed, have to move the entrance pole and meter to the shed, if I wanted a hybrid system with battery backup of the whole enterprise. After doing some...

    After three days of reading, I think I have better questions! Looking for AIO with 200A utility pass through......

    I have posted several times in the last couple days. I have time on my hands, cannot lift or be outside due to cataract surgery, so dedicating my time to figuring out what the family farm needs for solar. -- I have verified that the local utility Rolling Hills allows for net metering and grid...

    Contemplating a hybrid system instead of just grid-tie, but having trouble thinking through layout. Roof 400 ft away from most of loads/service entry

    My family farm has a large shed, 60x120 approx with a great southern exposure, metal roof that a good pitch etc. But the service entrance for the house, and much of the load (like large motors, fans, water pumps, welders etc) fans out from the meter pole, about 400 ft from the shed. With plain...

    Hello from KC. I have a question and this forum seems active. ........ Copper versus Alu busbar???

    Hello from Kansas City. I used to frequent Arizona Wind and Sun forum and gained (and contributed a bit) knowledge there through the years. Designed a system for my pole barn in 2008-09 but let an installer actually do the install, as here in KC there was serious money at stake from then KCP&L...
