Help determining what I need

For simplicity purposes it is probably better to go with 1 x 40A charge controller as opposed to 2 x 30A controller. However, the 30A controllers allow up to 400W of PV input, so you actually just need 1 x 30A controller and not both that you purchased.

The tray cables that came equipped with your kit is for connecting your controller to your battery bank. We would recommend, if you haven't done so already, to purchase a 40ft adaptor kit, which is the cable that connects from the solar panel to the charge controller. this is where you have some play room for distances between solar panels and charge controllers.

Unfortunately, since our adaptor kits are only sold in 10AWG and 12AWG for the time being, you can expect a voltage loss of about 7%. We try and keep voltage loss to no more than 2-3% normally, so that's something to consider.

For connecting your batteries together (as they are all 12V), you will need a battery interconnect cable to use your AC appliances, you need an inverter. We offer several models in the 500W,1000W, and 2000W. Given the electronics you want to power and assuming you wouldn't be running all electronics at the same time, a 500W inverter might be suitable. Keep in mind things change for bigger appliances such as fridges and microwaves and those will more than likely not work on a 500W inverter, unless it's DC.

In total, your setup would more or less look like this:

Method:

-4 x 100W panels connected in parallel using 3 x branch connectors. Your kits should have provided you with a set each so perhaps get one more.
-40' adaptor kit set 10-12AWG,
-30A charge controller
-Tray cable to connect to battery positive and negative posts
-6 x battery interconnects to connect your batteries in parallel to each other. 4AWG for 500W inverter, 2AWG for 1000W inverter
-500W or 1000W inverter (they come equipped with cables).


Here's a rough diagram of a basic system: In your setup you will have more batteries:




Hope this helps!
