This is the new Tracer AN Series MPPT controller, only recently released. Tracer model 3010AN 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. Improvements include* Inbuilt display showing real-time data* Integration with MT-50 display* Faster, more accurate tracking (Immediate on boot up, 99.5% accuracy)* Higher conversion efficiency (98%)* Ability to connect a larger array. The controller has the ability to restrict the charging current, so it does not exceed 30A The benefit it more power during off off peak times.Electronic protection: over charging, over discharging, overload, short circuit, and reverse polarity.RJ45 interface for use with optional MT-50 meter $55.00 SPECIFICATIONSBattery voltage: 12V/24V (auto detect)Maximum PV Open-circuit Voltage (Voc): 100V MaxRated PV Size: 390W/780WMax PV Size: 580W at 12 volt 1170W at 24 voltMaximum PV Current: 30AMaximum charging Current: 30AMaximum Load Current: 30AWorking temperature: -20 ~ +45CWeight: 1.2 kgDimensions: 228 mm × 164 mm × 55 mm
