Solar Battery Monitor

About Solar Battery Monitor

Solar Battery Monitor lets you monitor and control your solar battery system in real time via Bluetooth (BLE).

Main Panel
View your battery's state of charge (SOC), voltage, current, power, and temperature with an intuitive circular indicator. Includes an energy flow diagram showing the charge/discharge direction between source, battery, and load.

Voltage per Cell
Detailed graph of each cell's individual voltage, with minimum and maximum indicators to quickly detect imbalances.

Smart Estimates
Automatically calculates the time remaining until full charge or full discharge, available energy, and estimated capacity.

Performance Monitor
Records monitoring sessions with a built-in timer. Analyzes SOC variation, average current consumption, total energy consumed, and voltage evolution per cell with real-time graphs.

Bluetooth Scanner
Detects nearby BMS devices, displays signal strength, and allows direct connection with a single tap.

BMS Configuration
Control charge and discharge MOSFETs, send custom hexadecimal commands, and review the communication history with your BMS.

Multi-Protocol
Compatible with the most popular BMS protocols: PACEEX, Daly, JBD/Xiaoxiang, and JK. Automatic protocol detection upon connection.

Simulator Mode
Test all functions without the need for real hardware. Ideal for exploring the app before connecting your system.
