I have 11.5Kw PV panels connected to 10.22Kw of

I have 11.5Kw PV panels connected to 10.22Kw of micro-inverters feeding a 60A breaker in my 100A subpanel in my garage (grid tied). The subpanel is connected to a 100A breaker in my 200A main service panel in my house. The micro-inverters disconnect the PV panels when there is a power failure to avoid back-feeding the grid. Of course, since my solar array is connected to a subpanel, the micro-inverters are not looking at grid power directly but to my home's electrical system. I want to add a standby generator; for multiple reasons preferably located behind my garage. To avoid the micro-inverters from re-connecting the PV array when the generator re-energizes my home electrical system, the PV array must be isolated when on generator power.My first idea was that I need two Automatic Transfer Switches with one some 150 feet of wire away. Can I do this? Can one be the master ATS, the other the slave?My second idea - Generac has a 50A Smart Management Module (SMM) with a lockout switch that isolates the circuit to which it is wired. I still have the ATS some 150 feet away. Is there any reason I can't have the ATS so remote from the Genset? Alternatively; if I put the generator at the house; is there any reason the SMM cannot be so remote from the ATS?

Hi, I just purchased a double pole double throw switch because I want to essentially share the 30 AMP breaker between a dryer and a hot water heater. I have a TC10323R Model 9 switch which is rated for 100 AMP. When the switch is up, it will only provide power to the dryer. When the switch is down, it will only provide power to the hot water heater. When the switch is in the middle, it provides no power to either device. My question is, 'How do I correctly wire the double throw switch?'

I am building a tiny home with a generator powering it while mobile. The generator does not bond the neutral to the ground.I have a transfer switch that is installed before the main breaker. Should I bond the neutral and the ground together at the transfer switch, then ground the system to my trailer?I plan on bonding the ground to the neutral the the transfer switch because it will be isolated off the system when city power is connected.Would I just need to ground the breaker box to the transfer switch to ensure proper code?

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.
