A 30 amp solar charge controller can handle a specific number of watts, but the exact number depends on your battery voltage. Getting this wrong can damage your equipment or waste your solar panel investment. For a 12-volt system, a 30 amp controller maxes out at roughly 360 watts (30A x 12V). If you have … Read more
A PWM solar charge controller works like a smart switch between your solar panels and battery. It matters because it protects your battery from overcharging and helps your system last longer. Unlike a simple on-off switch, PWM technology pulses power in tiny bursts to match the battery’s voltage. This careful pulsing can boost charging efficiency … Read more
When you see “Bulk” on your solar charge controller, it means the first stage of charging your battery. This is when the controller sends as much power as possible from the solar panels to refill the battery quickly. During Bulk mode, the voltage rises steadily until it hits a set point, but the current stays … Read more
I see this question a lot from people setting up their own solar systems. Getting the mounting wrong can cause strange errors that are hard to diagnose later.
