The Off-Grid Controller allows you to monitor and control your system, wherever you are. Easily installed, you can now greatly expand your understanding and functionality of your existing or newly installed off-grid system.
Designed to meet the various requirements of off-grid systems worldwide, the Off-Grid
Controller provides you with real time, accurate measurements of your system and
environment. It allows you to create actions such as controlling relays to manage AC or DC
electrical circuits or start generators. These actions can be set to respond to changes in
generation consumption and the environment such as available solar power, battery state of charge (SoC) or temperature variations.
The core monitoring & control functionality includes:
- Battery DC Voltage: 18v to 75v
- DC Current: -300A to +300A. Up to 10 sensors with core version
- AC Voltage: 230VAC
- AC Current: -100A to +100A. Up to 13 sensors with core version
- Multi-function inputs: Up to 10 inputs for sensors, including combined temperature & humidity yet fully customisable for a broad array of sensors
- IR and PWM Output: Control up to 4 IR devices (eg. advanced control of air conditioning units) or small motors for home automation
- Relay control: Manage up to 6 circuits, including 230VAC circuits using DIN-Rail SSR relays
