Battery data
- State of charge and remaining capacity
- Voltage, current and power (charging or discharging)
- Each cell voltage, with highest, lowest and spread
- Temperatures of cells and electronics
- Cycle count and state of health
- Warnings and protections reported by the BMS
The exact set depends on the battery model and its firmware. We validate on Felicity batteries before shipping; tell us your model when you order.
Batteries in parallel
Larger installations parallel several Felicity batteries, each with its own address on the RS485 link. Reading all of them from one box is part of our test plan; tell us how many you have.
Displays
| Display | Content |
|---|---|
| Box screen | Charge, voltage, current, power, status, temperature |
Local dashboard (http://moniwatt.local) | All live values, cell chart, alarms, daily curves |

| JSON API | Every value for scripts and other platforms |
| Remote dashboard (optional) | Access from anywhere, history, CSV, offline alerts |
Respectful of your installation
The box reads only. It changes no battery setting and leaves the link between your battery and inverter exactly as your installer set it.
