Off-Grid Energy Monitoring and Controls

Power monitoring and controls for any battery connected solar system.

Features

Power monitoring for any type of battery setup.

Real-Time Data

Quickly understand current system conditions from anywhere

  • Battery Charge Level
  • Energy Production and Consumption
  • Estimated Runtime

Open System

Own your data. Data is stored locally on the monitor as well as on a removable memory card. Measurements stored every 5 seconds to the SD card providing lots of detail into system operation.

Historical Data

Monitor production and consumption data over time. Can be used to:

  • Identify system issues
  • Optimize the system for maximum production
  • Plan for expansions

Intelligent Controls

  • Reserve battery capacity when switching between grid and battery power
  • Run heavier loads only when production conditions are ideal
  • Harness excess power production with control of a 'dump' load
  • Conserve power in anticipation of weather events or planned maintenance

Technical Specifications

Please note - since the product is still in the design phase, these technical details may change. Please sign up for our mailer list, if we make changes we will keep you informed.
