I didn't mean AC as air conditioning, but for alternating current. The shorter you can make the DC (direct current)photo voltaic leads from the panels to the charge controller and the charge controller to the batteries the better. My run is about 14' and I use 2 awg marine battery cable from the junction box for the panels to the charge controller and 4' of 2/0 awg marine battery cable from the charge controller to the batteries

I will be really close to what you've got then. I'm wondering if 4 100W panels is enough or too much. I'm not running air conditioning or a microwave (just don't like them) or a coffee maker (I use a press) or a hair dryer. Will be running a fan or two, lights (LED where I can), flat screen and cable box, wireless router, laptops, cell phones, whatever the refrigerator uses while it's also on gas. Am attaching a large additional propane tank so I can use my stove/oven and running 2 oil radient heaters. What do you think?

We are running on 3 135 watt panels right now. I am adding another 100 watt panel. We have more than enough charging capacity, but need more battery. We have 330 amp/hr. I will be replacing them with 4 Trojan SCS 225 Group 31 batteries and we will then have 520 amp/hr.

Our neighbor has one 135 watt panel and 220 amp/hr of battery and with his amount of TV and other 12 volt use keeps his batteries fully charged with very little generator use.
