PWM MPPT Heater Charging Controller for Solar Solar Panels ACTii AC7391

Delivery within 3-4 days.
PWM controller for heaters with the algorithm of searching for the maximum MPPT power point from photovoltaic panels.

The controller enables the supply of standard DHW electric boilers from solar panels

The solar panel works at maximum power only at optimal voltage. Connecting the heater directly to the photovoltaic panel causes too much load on it and, as a result, a voltage drop. At reduced operating voltage, the panel produces even several times less current than at optimal voltage. The use of a charge regulator eliminates this problem. Even on cloudy days, it will be possible to heat the water in the boiler.

The regulator is supplemented with a buffer module containing capacitors, choke and diodes, which enables higher efficiency (up to 30%) and reduction of interference caused by PWM regulation.

The controller is equipped with a temperature sensor, which allows you to stop heating the boiler above the set temperature.

The device has been equipped with an additional relay output (potential-free), which allows external devices to be notified that water heating has been completed (the set temperature has been reached) or that there has been a device failure. This output allows you to connect additional devices.

Description

PWM controller for heaters with the algorithm of searching for the maximum MPPT power point from photovoltaic panels.

The controller enables the supply of standard DHW electric boilers from solar panels

The solar panel works at maximum power only at optimal voltage. Connecting the heater directly to the photovoltaic panel causes too much load on it and, as a result, a voltage drop. At reduced operating voltage, the panel produces even several times less current than at optimal voltage. The use of a charge regulator eliminates this problem.

Specification

Parameters

Supply voltage: 11V to 14.4V

Panel voltage: From 10V to 400V DC

Panels current: MAX 10A

Maximum heater power: 2kW

Maximum power of panels: 2kW

The current drawn from the power supply without cooling: 0.08 A

The current drawn from the power supply with cooling: 0.23A

Temperature measurement accuracy of 0.1 degrees

Modes of operation:

The regulator has the ability to change the mode to work in the area between min and max voltage, as was the case in earlier versions. This option is especially useful for wind farms.

Mode one:

It is fully automatic and starts working as soon as it is connected. When the voltage on

input exceeds the minimum voltage threshold set by the MINUS button.

If the voltage during tuning falls below this value, the search remains

interrupted. Setting the minimum value allows free heating

water and at the same time the possibility of charging the batteries.

Second mode:

Possibility to set activation voltage thresholds (from which it starts to increase

PWM value) and the maximum voltage (from which the duty cycle

equals 100%), i.e. the entire energy of the cells goes directly to the heater.

Additionally, the use of this method enables the panels to be kept at the MPPT point

(highest power point), and is especially useful for power plants

wind. In this case, it does not allow excessive acceleration

turbine as well as allows its free start.
