Power Master MPPT Charge Controllers

A professional range of powerful MPPT solar charge controllers (regulators) from 50Amp to 160Amp with battery charge management, state of charge information,suitable for both solar and wind turbine systems.

Built-in battery energy monitor tracks power production and consumption to calculate the energy remaining in battery state of charge (SOC) is displayed in percent full, amp-hours, watt-hours, and 90days of energy-harvest history is stored in the solar charger.

Continuous output power rating without de-rating at up to 50°C ambient temperature.
Supports flooded Lead Acid (FLA), GEL, and Absorbed Glass Mat (AGM) batteries, 2/3/4 Stage charging with adjustable set point.
Wire the PV modules in series up to 112VDC normal (140VDC Max).

Built-in temperature compensation function for safe and complete charging.Optimal Solar Maximum Power Point Tracking Solar Solar Controller which can be paralleled (Max. 16 sets) subject to demand.
