On average you can expect 1600-2600 Wh or 260-320 watts out per hour from your 400W solar panel. The difference will depend on the weather conditions & solar panel tilt angle. Under ideal conditions, you can expect 400 watts of power per hour from your solar panel but it will rarely happen
In short, For a 400W solar panel kit, you'll need a 40A charge controller (MPPT is recommended), 150Ah lithium or 300Ah lead-acid batteries The size of the inverter and cable will depend on your usage which I'm gonna share with you in detail. First of all, now let's calculate how many watt-hours you can expect from your 400W solar panel per day
But with an MPPT charge controller, it will lower the voltage to 14V but will increase the amps to 28Amps (400/14 = 28A) PWM charge controller can be used for small capacity solar panels but for above 100W solar panels an MPPT charge controller is recommended.
For a 12v 400W solar system, you'll need a 6 AWG size wire to connect the solar panels with the charge controller and from the charge controller to the battery And with the help of "chart 2" select the size of the cable to power your inverter from the battery bank
For example, if you're going with a 12v system. (12v 400W solar panels, 12v battery) you'll need a 40A charge controller with 400W solar panels to charge your 12v battery.
Depending on the sunlight intensity the voltage of your solar panel's output will change accordingly. e.g at the standard sunlight conditions you can expect 18-20 voltage output from your 12v solar panel system so the charge controller will lower the voltage to match the voltage of your battery.
