How much power does a DIY solar system use?

This isn't our first rodeo - we have a similar install video of our much larger, more complicated DIY solar system - it has 10kw of solar, 28kwh of lithium battery storage, and 5000w of 120V AC power. We’ll be referring to this project a lot as it informed a lot of the decisions we’ve made for this system.

How do you charge a solar power combiner?

Now let’s turn that solar power on. Go outside to the combiner box and flip the breaker on the inputs you’re using. Then go inside and turn on the 20amp Breaker. You’ll see both lights turn on in the DC Midnite SPD, and the charge controller will slowly ramp up until the full amount of power is coming in. Now you’re charging your battery!

How do solar panels connect in series & parallel?

Connecting in series combines the voltage of each panel, and connecting in parallel combines the amps of each panel. Here's how the math worked out. Each 250W solar panel (37V, 8A) connected 6 in series produced an array with 1,500 Watts, 230 Volts, & 8 Amps. Then connecting both arrays in parallel created a 3000W, 230V, 16A solar panel system.

How many volts does a solar panel add?

When connecting in series, you take the positive of the first panel and connect it to the negative of the second panel. Then the positive of the 2nd panel to the negative of the 3rd panel, and so on down the line. This means that each panel adds an additional 37 volts for a total of nearly 230 volts.
