General Information

The Commander Series MPPT charge controllers are suitable for various off-grid solar

applications. It protects the battery from being over-charged by the solar modules and

over-discharged by the loads. The controller features a smart tracking algorithm that

maximizes the energy from the solar PV module(s) and charge the battery. At the same

time, the low voltage disconnect function (LVD) will prevent the battery from over

discharging.

The Commander’s charging process has been optimized for long battery life and

improved system performance. The comprehensive self-diagnostics and electronic

protection functions can prevent damage from installation mistakes or system faults. In

addition, the charge controller has an RJ45 interface to allow communication with the MT-

50 meter.

MPPT Technology

The MPPT Charge Controller utilizes Maximum Power Point Tracking technology to

extract maximum power from the solar module(s). The tracking algorithm is fully

automatic and does not require user adjustment. MPPT technology will track the array’s

maximum power point voltage (V

) as it varies with weather conditions, ensuring that the

maximum power is harvested from the array throughout the course of the day.

Current Boost

In many cases, the MPPT charge controller will “boost” up the current in the solar system.

The current does not come out of thin air. Instead, the power generated in the solar panels

is the same power that is transmitted into the battery bank. Power is the product of Voltage

(V) x Amperage (A).
