What does a charge controller do?
A charge controller sits between your solar panels and your battery and regulates the charging current. Without a controller, a solar panel would overcharge and damage your battery. The controller monitors the battery voltage and constantly adjusts the charging current — this way, your battery is charged safely and efficiently. Almost all controllers also protect against reverse polarity and short circuits.
PWM or MPPT — which do you choose?
PWM controllers are simple, reliable, and affordable. The rating of a PWM controller is directly proportional to the system voltage: a 10A controller at 12V can handle a maximum of 120W of panel power. MPPT controllers work differently and smarter — they can handle more panel power than the charging current alone suggests, and manufacturers like Victron even advise connecting 30% more peak watts than the nominal controller capacity. For two or more panels, or if you want to expand later, MPPT is always the better choice.
Which controller is right for my installation?
The right choice depends on your panel power, system voltage, and controller type. With PWM, the ratio is simple: the controller capacity (in amperes) multiplied by the system voltage gives the maximum panel power. With MPPT, it's different — always consult the specifications of the specific model, as each MPPT controller has its own maximum PV input power and voltage. Unsure? Contact us, and we'll help you find the right match.
System voltage: 12V, 24V, or 48V?
Most motorhomes and boats operate on 12V. A 24V system is more efficient at higher power levels and longer cable distances — the current is half at the same power, which allows for thinner cabling. 48V is reserved for larger off-grid installations. Always check the voltage of your existing battery bank before choosing a controller — the system voltage of the controller and battery must match.
