SunPulse: Solar Inverter Live

See exactly where your solar power goes, second by second.

SunPulse reads your hybrid or grid-tie inverter directly over your home Wi-Fi and shows a live power-flow view: solar → battery → home → grid. No cloud account, no lag, no waiting for a vendor app to refresh.

WORKS WITH THE HARDWARE YOU ALREADY HAVE
• Wi-Fi logger sticks that use the Solarman V5 protocol (port 8899)
• SunSpec Modbus TCP over LAN (port 502)
• Smart dongles with Modbus TCP enabled (step-by-step guide inside)
• Low-cost RS485 → Wi-Fi converters (EW11, USR-W610 and similar)
• USB OTG RS485 cables for installers working on site
• Auto-scan finds your inverter on the network and detects the model, so you don't need to know its IP address

LIVE DASHBOARD
• Animated power flow for solar, battery, home load and grid import/export
• PV string voltage and current, battery SOC, voltage, temperature and time to full
• Grid voltage per phase, frequency, inverter temperature and work mode
• Today's production, self-powered percentage and peak power

SEE THE MONEY YOU SAVE
• Savings in your own currency, today, this month and lifetime
• Normal, tiered and time-of-use tariffs, plus net-billing / net-metering export credit
• Ready-made presets for some utilities, or enter any rate yourself
• Payback tracker and CO₂ avoided

ALERTS IN PLAIN LANGUAGE
• Power cut / grid lost, low battery, battery full
• Inverter fault codes translated into plain words, with what to do next
• Low-yield warning when output is far below what the weather allows (dirty panels or new shade)

OLD PHONE = 24/7 DATALOGGER
Leave a spare phone on its charger at home. It records every reading in the background, and your main phone syncs the full history whenever you're back on home Wi-Fi. No more gaps in your charts.

MORE TOOLS
• Wall display mode: an always-on AMOLED energy screen for a tablet, with night dimming and pixel shift
• Home-screen widgets: live power, battery and today's kWh
• MQTT bridge with Home Assistant auto-discovery
• Register-map profile editor: add new inverter models or import JSON profiles
• Export history to CSV
• Installer console for raw Modbus reads
• Demo simulator: explore every screen without an inverter

SAFE BY DEFAULT
SunPulse is read-only out of the box. Changing inverter settings (work mode, export limit) is an advanced Pro tool with clear warnings, a backup of the old value and read-back after writing.

FREE AND PRO
Free: live monitoring of one inverter and 7 days of history.
Pro (one-time purchase, no subscription): unlimited history, multiple inverters, push alerts, widgets, datalogger mode, MQTT bridge, CSV export, advanced register tools and no ads.

PRIVACY
Your energy data stays on your own network. SunPulse needs no account and does not upload your readings to any server.

Note: SunPulse is an independent app. It is not made by, affiliated with or endorsed by any inverter or data-logger manufacturer. Product and protocol names are used only to describe compatibility. Supported features depend on your inverter model and firmware.
