NO!!! These numbers are absolutely NOT correct. The 3hp value is the power OUTPUT of the pump motor, NOT the power input. Please go...

Something I could add is the amount of solar needed for that sized battery. It's going to depend in part with the panels themselves...

I think it might be appropriate at this point to suggest a course change. Yes, you can build a solar system that can power your...

What I have read is that soft-start electronics on a well-pump is a BAD idea. My understanding is that water lubricates the pump...

Are these your batteries? When measured at the 20hr rate, they are only 424Ah. That being said, the charge rate you are going them...

Can you take a pic of the little meter you have? I'm thinking that most likely you have it set to the wrong parameter and you reading...

Is this your freezer? Looking at comparable models at HomeDepot, I'd guestimate your unit might consume between 1.6 and 1.8kWh of...

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...
