Setting Up Your DIY Solar System
Alrighty guys this is just a quick DIY solar system you're only going to need four things this is one victron smart solar charge controller you're also going to need wires as well you're going to need a battery box your battery box your battery and your solar panel now I'm also going to show you some add-ons that you can have in that just make it a lot easier this is going to tell you the everything that's exactly going on your battery if you get a good enough battery box it still tell you the voltage but it's easier to read when you have a smart shot.
Wiring and Simplicity
Now getting back to the actual system itself you're going to require not much wires you're going to require wiring for your solar panels and you're going to require wiring for your battery box battery boxes mostly come wide so that's not too big of a problem but this is how simple of a system where you need and that wire just goes out to the back of my solar panel this provides free solar for my house.

Frequently Asked Questions
Q1: What specific Victron charge controller model is being referred to in this DIY system? A1: The system references a "victron smart solar charge controller." Given the common sizing for DIY projects and the keyword, a Victron SmartSolar MPPT 100/20 (100V maximum PV open circuit voltage, 20A maximum charge current) is a strong candidate for this type of simple setup.
Q2: Why is a "smart shot" (smart shunt) considered a useful add-on, even if the battery box shows voltage? A2: While a battery box might indicate basic voltage, a smart shunt provides a comprehensive view of your battery's health and usage. It offers precise readings for state of charge, current draw, power consumption, and historical data, making it much easier to manage and understand your battery's performance than just a voltage reading.
Q3: Is this simple DIY system capable of powering an entire house? A3: This "quick DIY solar system" as described is designed for providing "free solar for my house," implying supplemental power or power for specific loads, rather than fully powering an entire residential property. Scaling up to power a whole house would require a significantly larger array of solar panels, a larger battery bank, and typically an inverter (not mentioned in this basic setup).
