I'm planning to install two 200W solar panels on my company's trailer and need advice on what size solar charge controller to use, as well as the appropriate breaker size. Any recommendations? Thanks!

It really depends on the specifications of your panels, but usually, something like this [controller](https://amzn.to/3P3be5P) should be fine. Since you're using two 200W panels, for the breaker between the panels and the controller, a 15 amp breaker should be more than enough. Just keep in mind that the breaker on the other side will depend on your battery setup and inverter. So you'll want to consider that too!
For your 400W setup, a Victron 50 amp controller or a Renogy 40 amp controller would definitely work. But honestly, you might want to consider something smaller since 400W isn't that high of a capacity. Check out this [controller](https://amzn.to/3P3be5P); it should be sufficient for your needs!
I agree, the Victron is usually a great brand, but you shouldn't need that much capacity for 400W. Going with a smaller unit is definitely a smart move!
