Kits her rarely a good buy. This one included. That PWM charge controller is garbage. Comparable panels are this price all day on Amazon.

I was considering that as well...when doing the math on the whole build-out, the components I'm thinking of:

$341.99 - Renogy 200W 12V 40A Kit (2 Panels) [amazon.com]
$319.99 - Chins LiFePO4 Battery 12v 100AH [amazon.com]
$189.97 - Krieger 2000W Inverter [amazon.com]
$35.99 - Renogy Bluetooth Module [amazon.com]
----------------------------------------------
$887.94 Total

That has the same power storage capacity as the Delta 2, can be expanded to another battery (and more panels as needed)...and can have parts swapped out as needed. Obviously, there will be some additional cost for misc wires/fuses/bus bar, etc

Assuming money being close to the same for both of these solutions, part of it also comes down to me wanting to learn this stuff better. I work in IT, and rarely do "hands-on" projects like this, so I thought it would be a cool thing to try. Ultimately I want to put this on my shed and be able to use it to charge a golf cart or use as backup power in a power outage.

This is a good deal even without the charge controller and wires. I have a bunch of these panels and they are superb.

I was looking at the Renogy 200W system that includes a 40A MPPT [amazon.com]as something I could "grow into" as needed. Any thoughts on that vs whats been posted here? Still learning as I go on this. I was going to start with the 200W kit + a 12v 100Ah LiFePO4 Battery + 2000w Inverter (recognizing the inverter is likely overkill for just a single 12v battery...but with this setup, I could buy additional batteries/panels as needed)

I am still researching installing solar panel on top of my patio cover, but what you said makes sense.

Why not just get a EcoFlow Delta 2 and a solar panel?

This question may be too complicated for this thread, but given there are knowledgeable people here, I figured I might as well ask.

I have a professionally installed system with the following:

8.8 kw total capacity (27 of the SunPower 327 panels)
2 SunnyBoy 3800 inverters

My understanding is that this configuration can handle more panels and I would like to add more. I planned it before getting my EV which makes it so I consume more than I produce.

How difficult is it to add panels to an existing array? Does anyone have experience either as a DIY project or hiring a company to do it?

You can buy pieces separately for same price. HDepot runs solar deals about once per month on special buy BTW. I have 8 of these in service since '17

Not hard if you've got the space, but need to stay with same existing watt panels…n a nutshell

Going with a modified sine wave inverter would be a downgrade. It all depends what you're using it for but it's not safe to use with sensitive electronics. The other benefit buying an all-in-one unit is it's an all-in-one unit. You grab it by the handle and off it goes if you want to take it camping. You can also charge it from your car or AC power. Wi-Fi and app controls with firmware updates that come with new features and bug fixes. It's also expandable from 1kWh to 2 or 3kWh. You would also have USBA and USBC outputs. 12V outputs. Built-in fans to keep things cool and the ability to monitor the interior temperature. Solar is up to 60V at 15A or 500W.

Good point on the modified sine wave, I actually hadnt noticed that...so would need to swap that out for a pure sine wave inverter.

All depends on how the installer wired them, if you have spare MPPT inputs that allow for additional panels sure! you can overpanel grid-tie inverts mostly, just depends on the spec. These panels are definitely not them! these are for the DIY shed project, overpriced and not designed for big systems in the least bit.

Doesnt matter if they are different if they connect to a open MPPT input on the inverters. voltage is the key number here.

Your setup is very good compared to the kit. MPPT charge controller makes a big difference. Depending on the setup, MPPT can add an additional 5-20% energy for same amount of panels.

The big thing is to look at all the electrical theory for the solar panel circuits. First make sure the Open Circuit Voltage of the panels you wish to add is pretty close to that of the existing panels. Also make sure OCV is not higher than the max input voltage on the solar charge controller.

There's many ways you can arrange the panels in multiple series loops to get the input voltage and current you want…but that's what it comes down to when adding panels to your system.
