TRACER 40amp 12/24v MPPT Controller
A genuine MPPT controller contains a maximum power point (MPP) tracker, which finds the MPP voltage of your array. Any additional voltage is converted into current. On 12V panels, you can expect a 10-15% improvement during bulk charging. However, the main benefit is the ability to run a higher voltage array on a lower voltage battery bank, up to 100V. This reduces the cost of wiring, connectors and circuit protection.
MPPT technology increase charge efficiency up to 30%.
