New Home Construction

[wolf pack]

I have twenty 280 watt panels, I have searched this forum and impressed with the combined knowledge, I have been unable to locate what I need to know on the install. Basically would like to do a 48 volt system with 4 12 volt battery's for a off grid system to Run my house That is being built. There will be no air conditioning, Mostly propane for the water heater and stove. I read up on the inverters and how to hook up the panels, in series or in parallel is my issue now. If someone could point me in the right direction, Many thanks in advance,

That is all going to depend on your charge controller.
I would recommend a matched set of charge controller to inverter all from the same manufacturer so that you can use the same monitoring.
You are going to have some series though for a series/parallel system but how it is done will depend on how high of voltage the CC allows.
Is your physical all south facing or East/west? or SE/SW?
shadows?

Thanks Butchdeal,

Looks like the panels are made by Sova Solar, model # SS280P-72, No charge controller or inverter made by them from what I can see, Facing south with 4-5 hours of partly shaded sun. I need to know what size controller to use and should I wire in panels in series or parallel ? I am new to solar and the voltages and amps confuse me. The panel info tag states, max power 280, open circuit voltage 44.4, voltage at pmax 36.7 and current at pmax 7.78. Looks like I need to change the battery bank to eight 6 volt battery's from my research

4 - 5 hours partially shaded sun !!

How much UNSHADED do you have ? PV panels don't work in shade. There are way$ to prevent shade from throttling back illuminated panels, but shade does not produce power.

I meant to get charge controller and inverter from the same company. not the same as the PV module company.

Like OutBack power for example. If you get inverter and charge controller from Outback then you can monitor both with the Mate3, you can even add in a battery monitor as well.

Mine 7k ground mount array was making 500 watts in the shade of the house in Michigan last night at 5pm.....Mike you need to upgrade.....

You are welcome to install all you want, I've got acres to put them on.

What is your recommended upgrade? My primary solution to shade is a chain saw. Bruce Roe

I think that might be the more economical solution

Wow. You have so many solar panels! I am currently staying in an apartment and I cannot wait for the day that I will be able to move into a house. To me, that's the dream. I am working every day and I am saving money every month in order to be able to buy one. I will speak with someone from midmodphoenix in order to help me with the design when this will come true. Besides the house, I would love to have some solar panels in order to make use out of this kind of electricity. Maybe I will even buy an electric car one day haha

In general, when buying a land plot through an agency, many clients have encountered such problems: The agency does not always have reliable information about engineering communications connected to your site. It is better to clarify this separately in the management companies. To adapt the foundation of a typical project to your site, it is better to perform geological surveys in advance. This will give detailed information about the depth of groundwater, the composition of the soil and help at the construction stage of the house. I decided to avoid all possible problems and entrusted the construction to the guys from the company boutique home plans who coped perfectly.
