TommaTech® MPPT Series is a series of MPPT charge controllers developed for on-grid photovoltaic systems with optional LCD display units (XDB1 / XDS1 / XDS2). TommaTech® MPPT Series Charge Controllers apply intelligent algorithm to maximize the amount of energy generated from PV arrays and at the same time minimize power loss in a wide operating range, and thus operate at high efficiency. TommaTech® Series Controller has the option of automatic power reduction at high temperature as well as limit protection function in charging current and charging power. In this way, the stability of the system is taken to the next level.
