Tracer series AN controller adopts MPPT technology (Maximum Power Point Tracking). The advanced tracking algorithm make the solar module operate at ideal voltage which the solar modules can produce the maximum available power. Compared to conventional PWM controller, MPPT technology increase charge efficiency up to 25% and decrease the power of solar array needed. Tracer has the ability to step-down the higher voltage solar array to recharge a lower voltage battery bank.
come with 5 years warranty.
New A-series Tracer has all the features of earlier Tracer models, and has a built in display. Fully USER definable settings using optional MT-50 ($49) or PC cable ($15) suitable for a wide range of battery types, and load timer, day/night, or disconnect settings - this makes it compatible with most LITHIUM BATTERIES. The MT-50 display is not required for selecting any of the three standard battery settings. 3 Stage charging: Bulk, Boost and Float, plus Equalize function. Settings for Flooded, Gel, Sealed batteries or user defined settings, contain algorithms to suit all lead acid battery types. Temperature Probe $25；eBOX WIFI $35
Suitable for use on 12 and 24 VDC systems MPPT Technology is around 98% efficient, which is much better than the old PWM type charging that is around 75% efficient MPPT technology takes the difference in voltage between your batteries and your solar panels and converts it into CHARGING AMPS for up to 45% + more output from your panels! Can take any Solar Input that is higher than your Battery Voltage and charge your batteries! Example: You can have a 24VDC solar panel and a 12VDC battery system, and the MPPT controller will turn the extra voltage into Amps!
