You've cranked your panel array up to handle a bigger load, but you're still flying blind on charge levels. Is the battery at 80%? 55%? You don't know until something dies. This Jaycar 30A PWM controller handles the higher current headroom, auto-detects 12V or 24V, and the LCD display shows you exactly what's going on — voltage, charge state, system status — without guessing. Bigger setup, same peace of mind. Add to cart and finally see your numbers
