Operational Description
ECO-N-T is a series PWM (Pulse Width Modulation) solar charge controller. It uses fast switching to
connect and disconnect the solar panel to the battery. This switching regulates the battery voltage
and charge current.
ECO-N-T will attempt to charge the battery up to a target voltage. The target voltage and duration is
determined by the charge state (Main, Boost, or Float). Either Main or Boost will be completed first and
then Float will occur for the remainder of the day. If solar energy is insufficient, or if too much load
energy is drawn from the battery during charging, the battery cannot be fully charged.
ECO-N-T adjusts the target charge voltage based on ambient temperature. Charge voltage is increased
in cold temperatures. Charge voltage is decreased in hot temperatures.
ECO-N-T provides a power output to supply DC loads with electricity. The voltage of this load output is
the battery voltage. Energy for the loads and for the controller’s self-consumption are drawn from the
battery.
To protect the battery from getting deeply discharged, ECO-N-T will disconnect the load output when
the battery voltage drops to a low SOC (state of charge). This is known as Low Voltage Disconnect
(LVD). When the battery is charged above the reconnect level, load power will turn on.
To protect connected loads, ECO-N-T will disconnect the load if the battery voltage rises too high.
ECO-N-T has over temperature protection. If the internal temperature rises higher than about 75°C
(e.g. at high charge currents and high ambient temperatures) the charge current will be decreased to
reduce internal heating. If the internal temperature is too high, it will also switch off the load current.
