MPM PWM Heater Charging Controller for Solar Solar Panels ACTii AC7391

Delivery within 3-4 days.
PWM regulator for heaters with the algorithm for searching the maximum MPPT power point from solar panels.
The controller enables the supply of standard DHW electric boilers from solar panels
The solar panel operates at maximum power only at the optimal voltage. Connecting the heater directly to the photovoltaic panel causes too heavy load and as a result 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.
A buffer module containing capacitors, a choke, diodes is added to the regulator, which allows greater efficiency (up to 30%) and reduction of interference caused by PWM regulation.
The controller is equipped with a temperature sensor, which allows the boiler to stop heating above the set temperature.
The device is equipped with an additional relay output (without potential) enabling notification of external devices that water heating has been completed (reaching the set temperature) or that the device has failed. This output allows you to connect additional devices.

Modes of operation:
The regulator has the ability to change the mode to work in the area between the min and max voltage, as it was in earlier versions. This option is especially useful for wind farms.
Mode one:
It is fully automatic and starts working immediately after connecting. When the voltage on
input exceeds the minimum voltage threshold set with 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 also the ability to charge batteries.
Second mode:
Switching voltage thresholds can be set (from which it starts to increase
PWM value) and maximum voltage (from which the duty cycle is filled)
is 100%), i.e. all the energy of the cells goes directly to the heater.
Additionally, the use of this method allows panels to be kept at MPPT
(the largest power point), and is especially useful for power stations
wind. In this case, it does not allow excessive acceleration
turbine as well as allows its free start.
