2017 Voltage Solar Setup Questions

Just wanted to get thoughts or suggestions on the setup we are currently doing on the 2017 Voltage 3970. We want to be able to run what ever we need to at any time. Mainly lights, water pump, water heater (propane) and a few outlets. Just one AC though for a few hours a day if needed. We have already installed the following:

24 - 120 watt flexible solar panels - https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
MidNite Solar Inc. Renewable Energy System Electrical Components and E-Panels
They are installed as follows: 4 strings of 3 panels (series/parallel) going to a Midnite Solar 150 MPPT charge controller. So that gives us (2) Midnite Solar 150 charge controllers each with 4 strings or 3 panels. Each panel is rated at 22.6 volts (so ruffly 66 volts coming in to each charge controller). IMP of the panels is 6.6 amps (roughly 18-24 amps to each charge controller) boosted to 50-60 (each controller) on a full sunny day.

4 - 6v Interstate L-16HCL batteries - https://www.interstatebatteries.com/products/l-16hcl
Wired in series/parallel for 12 volt systems. gives us 840ah (420 usable).

1 - 4000 watt AIMS Power Pure Sine Inverter -
We are going to connect this between the AC breaker panel and the automatic transfer switch and connect the Auto Gen Start connection to the Onan 5.5kw RVQG Gen eventually.

1 - EasyStart™ 364 (3-ton) Soft Starter - for (1) of the A/C units

10ga wire from roof to each charge controller
6ga wire from each charge controller to battery bank
4/0 wire from inverter to batter bank

Everything is fused properly. Just wanted to get anyone's thoughts, advice, criticism and so on.

We are fully prepared to build on the system and add/change/take out what ever we need to. The ending result is to be able to power anything at any time (within reason), have the Gen auto start when batteries go below 10.5 volts, Shore power and Gen power take priority.

Thanks for anything you can do!

Good idea. Definitely use the gas for hot water. Thanks for looking over it. Yes we did our homework. This is our second solar system we have installed. We learned alot from the first one.
