Charge Kontroller+
A Solar MPPT Charge Controller with WiFi Interface
Description
Charge Kontroller+ acts as a key interface between Solar Panel, Battery, Display Unit and Electric Appliances like fans and lights. It has an energy efficient MPPT based charge algorithm to charge the batteries with solar energy.
In addition, this acts as a power control box to control power supply to electrical appliances. It draws power from solar cells / battery with D/C power output and provides the regulated output to the loads. Its an Easy-to-Use device with below smart features:
- Load control over Wi-Fi / USB-C type / Manual Switch’s
- Telemetry data over Wi-Fi / USB-C type
- Manual operation of load control
- LED indicators to show status of power supply.
