Late to the party, but this was already discussed in length here: https://diysolarforum.com/threads/sol-ark-8-12-15k-with-tigo-ts4-a-o.45069/ Simply apply power to the Tigo gateway, Install a 12VDC relay on the Sol-Ark 12 RSD output, connect the relay contacts to the Tigo gateway aux terminals...

Possibly. It depends on your use cases. If you don't require batteries then microinverters may make sense. The Sol-Ark is definitely worth the money if it fits your needs. Honestly, you haven't provided enough information to give an informed opinion. I suggest you read through the forum...

Oops

Yes, you should use two separate 200A fused disconnects. One for each inverter. With a single 400A disconnect, it would be possible to pass more than 200A through a single inverter which could cause things to smoke. You should check with your utility company as they may require you to have a...

My advice is to take the $100 and put it towards purchasing the correct equipment for the job.

I'm pretty sure you want a grid tied system. Your diagram shows the "Grid" wired (tied) to your inverter. The first thing that you need to do is study your loads. Search the forum for "power audit". Let's assume that your 20KW battery could power all of your loads from 1 - 8 PM., and you would...

I like your description of the "Big Red Switch" :)

Does open or closed loop battery have anything to do with the generator kicking on? It's not supposed to, but there have been some anomalies cause by closed loop communications. What are your TOU settings? What are your settings for Battery Shutdown, Battery Low, Battery Restart? Gen Start %...

What version firmware are you on? What type of batteries? Open loop or closed loop?

I would throw some scrapple, pork roll/tailored ham and spam in with the sausage group.

You have to enable TOU, have the charge box checked in the TOU time slot, and have Gen charge checked. You may want to search the forum for other post related to that generator starting problem. Sol-Ark is adding additional generator programming but it will not be available for several months.

Correct, I forgot about that. Can't use Gen port with AC Coupling on Load side.

Aside from the other info, how far is it from string to inverter?

I'm not disagreeing with you. I'm just stating what the code is allowing. Personally I like the idea of putting fuses at the source. I alsot think that if a string is fused at the source, is 300 VDC or less, and 30A or less, that we should throw out all the extraneous wiring requirement (like...

What model inverter are you tying them to? What is the MAX MPPT voltage and wattage per MPPT?
