Couple of options. Looking at the shadows from your loquat at 11:43am, it appears that you have your array facing East, is that...

Took a bit of digging to find out the actual Vmp? Don't understand why they have to make it so hard? Looking at the specs, your string...

The voltage values are rather high, so are you confusing the Voc with the Vmp? The Voc is the voltage of the panels when NO current is...

Yes, please post pics. A mount holding only four panels is not very big, so it might be worthwhile to simply remove it. How high off...

This is the wiring diagram I used to connect mine. Hope you will find it helpful

A very important point is the mis-conception that a 12V panel produces 12V. It does not. The designation "12V" means that the panel...

During the last partial eclipse here in California, I was pumping irrigation water that day, after watering my orchard trees earlier...

You mentioned the RV, so I'll assume that these panels are going to be mounted flat on the roof? In that case, I'd de-rate their output...

Chrissky is making a very important point here. If there's the possibility that both your 1.5kW air-conditioner, and your 1.5kW water...

48V is definately the way to go. Take a hard look at Outback's Radian, especially the 8048. I think that would be perfect for your...

You have been misinformed. High-idle consumption has nothing to do with whether or not the inverter is hybrid or not, it really has to...

Personally, I'd want something a bit higher quality than EG4. Instead of fretting about array orientation, why not build single-pole...

Shop for MorningStar, Midnight, Outback, Schneider, and Victron products. All are top, tier-1 quality.

RV/automotive accessories like radios, TVs, or cocktail blenders are designed to operate at 12V. If you connected their power terminals...

Hello Clem, I have a niece living next to you in Adelaide, and I love that part of Australia, it sounds like your location is just a...

Let's just throw out a few numbers here and see what we come up with. First, let's assume your air-conditioner is a 5000W unit running...

I threw the parameters for your panels into Midnight's string calculator and see that for SSE's example of -25F above, your Voc might go...

It really is a apples vs oranges comparision. The kind of inverter you'd put on a hand-truck system is the kind of inverter you can...

I think it would be very valuable to post again when the results of your research results in some hands-on experience as to what...

Building 6" walls to accomidate thicker insulation is very well established, and I used that in the construction of my own cabin. I...
