I want to use this switch: To wire an off-grid application.

I want to use this switch:https://www.amazon.com/Leviton-1288-30-Amp-120-Volt-Double-Pole/dp/B003AUPTP8/ref=cm_cr_arp_d_product_top?ie=UTF8To wire an off-grid application. There will be two sources of 120 A/C power, one from a battery bank inverter and a second from a generator.I want to manually switch between the inverter and generator as needed. The output A/C line will be going into a single 20 AMP circuit.So essentially, I want to wire a DPDT with two A/C input sources to one output.Thank you.

I am installing a backup generator with an automatic

I am installing a backup generator with an automatic transfer switch. Regional building required me to install a 100 amp disconnect between the meter and the main panel. So now the main panel becomes a "sub panel". The ground and neutral are "bonded" in that main panel with bare copper connections to both a grounding also rod and water lines. I have also installed grounding connections to both a grounding rod and water line in the new disconnect box.Regional is now telling me since the old main panel is now considered a sub panel I must separate the grounds and neutrals in that panel even though the bonded connections are still connected to the grounding rod and water line.I don't understand why I must 'unbond' the ground and neutral since in my estimation nothing basically changed other than introducing a disconnect ahead of the main panel.Can you help me understand why I need to go thru this hassle or should I push back with an argument that even though the main is now considered a subpanel it is still properly isolated because of the grounding connections?

We are upgrading a 200 single service to a 600 amp main into

We are upgrading a 200 single service to a 600 amp main into 4 200 amp services (none of the services will actually draw more than 150 amps and three of them will draw less than 125 amps we may tie two of the services together?). We are not in a position at this time to invest in any generation equipment at this time as the upgrade is running 20K. All of these services will be in a newly built building, what can we do to make the installation of a generator into each of these 4 services? We are thinking that we'd be best off to have a different generator for each service as they will at time not have any need for back up power, what do you think? I see on line that a transfer switch for each one of the services (220 volt 200 amp.) would be close to $500.00, just don't have the $2k extra right now, can we put in a junction box that could be tied into, and would that make it easier?Thinking of running four generators at one time, how much propane volume and pressure would we need to be supplied to this building?

Regarding Solar Panel kit wheel RV trailer. I have a 2012

Regarding Solar Panel kit for 5th wheel RV trailer. I have a 2012 Montana Mountaineer edition by Keystone. It has a 50 amp cord for use where power is available. I'll be living in it this summer off grid. I have a 8000 watt portable generator that I can use to power the A/C and microwave etc. There are 400 watt solar kits available from Renology $680 Windy Nation $630. These both have four 100 watt panels. My trailer came with two 12 volt deep cycle batteries and there is ample room to add more. Do you think I should install one of these kits or put my own system together...or should I just use the generator to charge the batteries. There is space on the roof for about 10 panels but I'm wondering why they don't use two hundred or three hundred watt panels instead. My parking area forces me to park facing north just to complicate things. I dont want panels mounted to the ground because I want to use them in various locations. Should I get brackets that allow the panels to tilt? I realize I will be getting pretty good production during the summer months only.How many batteries should I use? There are two 12v batteries in there now.Should I get more or should I replace them with 4? 6v batteries?How long does it take to recharge the batteries from 50% with the generator running?Will a 400 watt system provide enough power to live comfortably to run a tv, lap top, LED lights, radio etc?We are in the mountains about 6200 ft so the A/C will only be needed during hot spells.
