Dual Axis PV Solar Panel Tracking Sun Tracker Electronic REI WiFi

Description

Set contains;

1. controller with WiFi module

3. light sensor

4. AC power line status sensor

REI Solar Tracker controller has a dedicated and innovative algorithm that allows you to work in areas with frequent cloud cover and changes in weather conditions. This is the only device that lets You get even 60% more kWh/Year from Your installation on a dual solar tracker (compared to a fixed installation). All other controllers can increase the yield by about 40%. We can implement any type of firmware to work with all kinds of 1 and 2 axis trackers.

It does not require expensive and cumbersome peripherals such as inclinometers or magnetometers. One irradiation sensor is enough to efficiently work with and accurately control the tracker set.

REI controllers have a noise filter, 2-row power supply, PWM / soft start / stop function, limit sensors and more logical inputs/outputs

Built-in bridges that control high-quality DC motors used in the automotive industry. Allows you to detect the load/amperage on the motors. Contains configurable functions to control soft start / stop motors.

Built-in cooperation with a grid power failure detection sensor, which makes the installation much safer. Very often there is a power outage before the storm.

As an option: programmable interface to control 2-3 phase AC inverters, BLDC/ STEPPER motor drivers.

Main differences to other products (optical/astronomic/hybrid)

1. Automotive h-bridge instead of relays (relays burn pretty fast and this is dangerous for motors when they are stuck in ON position, the limit switch will not help and the construction/motor will be broken.)

2. The limit switch works in a logical way not just voltage divider so we are insulating the noises ( This is the reason when the tracker is stopping here and there. It's dangerous especially when it should go to a flat position in wind hazards. Many times the tracker is not going back after the end of the day. Then the tracker is staying back to the sun in the morning and the controller is stuck with sensor readings. So You are losing a few hours of production.

2. It has a special algorithm that lets You be accurate even in semi clouds. Most of the available versions are going back and forth east limit to west limit making DC motors ovehitten.

3. You can use that controller for bigger installation with AC motors or BLDC/STEPPER drivers, we have separate I/O connectors programmed as You want.

4. You can connect a second wind speed sensor or weather station

5. We have PWM Soft start/stop for motors (can be switched on/off as needed + You can set max speed for each motor)

6. There is an amperage sensor on board to control motor overloads. Can be switched on/off

7. We have professional connectors - that reduce costs/time of service on the field.

8. Temperature senosts

9. WIFI module to grab the logs and control the device
