One of the most trusted manufacturers on the market, EPsolar combines reliability with performance to bring excellent value for money. The new Tracer-AN series from EPsolar builds on the great performance of the BN series whilst improving conversion efficiency and including a built-in LCD display, allowing keeping an eye on generation that much easier compared to older generations.

Conversion inefficiencies exceeding 98% and high speed maximum power point tracking (MPPT) ensure little to no power whatsoever is lost from your solar system. Protection measures include battery short circuit, reverse polarity and overcharge protection as well as temperature compensation (using optional temperature sensor) to ensure batteries last as long as they should.

The multi-function display allows for real-time monitoring of electrical readings, including battery voltage/charge current and PV string voltage/current. Fully programmable functions available with additional PC connection or remote meter.
