New to Solar Systems Commercial Installation

[clax]

I am new here and have been studying about solar.
I have a solar system to install, 4000 watt PV to be connected to a 7.5kva Inverter with 10/12v 200ah batteries making 120 volt total.
I have 16 units of 250 watt panel to install and any assistance to the best or possible installation info will be appreciated.
What is the best Charge regulator and size to match a 120 volt battery bank system.

I know there and kind and geeks with so much knowledge about solar here.

Over to you board members...

Hi Clax and welcome to Solar Panel Talk.

I dont want to rain on your parade but it seems you might have put the cart before the horse, usually you don't buy any equipment until your plan has been finalized.

I think the best thing for you would be start with reading the off grid stickys, the first thing you need to do is get a handle on your kilowatt hours per day requirement (helps determine usable kilowatt hours required) for summer and winter.

We also need to know a bit more about the install type and perhaps peak loads, what does the system have to do? There are a few here that have a bunch of knowledge on off grid systems, so post questions under off grid if its got anything to do with having batteries in the mix, cheers.
