Changelog

[2.0.0] – 2026-03-31

Added

• House Power sensor (register 40519) – previously incorrectly listed as cloud-only
• Grid Power sensor (register 40521) – previously incorrectly listed as cloud-only
• Solar Power sensor – calculated from active PV strings (more reliable than register 40523)
• Per-string PV Power sensors (W) for strings 1/2/3, calculated from current × PV voltage
• PV Voltage Global sensor (register 40598)
• Serial Number and Operation Mode diagnostic sensors
• Battery Nominal Capacity sensor
• Min SOC Limit, Battery Temp Warning Max/Min diagnostic sensors
• Inverter power limit sensors (nominal + current)
• Max Battery Discharge Power and Max Charge Power sensors (calculated from module count)
• House Consumption Today/Total energy sensors (calculated from energy balance)
• Solar Yield Today/Total energy sensors
• Configurable battery capacity – workaround for unreliable register 40528
• Configurable PV string count (1–3) – unused strings are ignored
• Phantom current filter – string currents below 0.05 A are treated as 0
• Configurable poll interval (5–60 seconds) via UI
• Options Flow – all settings editable after setup via Configure button
• Debug logging toggle in HA UI via manifest.json loggers field
• German and English translations for all config/options flow fields
• Heartbeat check at the start of each poll cycle – detects inverter unavailability immediately
• Automatic reconnect after inverter restart or network interruption – stale TCP connections are detected and cleanly closed, with reconnect on the next poll

Changed

• Switched from individual register reads to block reads (5 requests per poll cycle instead of ~25)
• Inverter Temperature register corrected to 40592 (was incorrectly mapped to 40600)
• inverter_ac_power (40530) now read as direct INT16 Watts (division by 100 removed)
• Power limit register offsets corrected (40546/40548/40550/40552)
• Registers 40550/40552 replaced by calculated values (were unreliable)
• const.py cleaned up – individual REG_* constants removed, block addressing used in coordinator
• sensor.py uses UnitOfApparentPower.VOLT_AMPERE instead of hardcoded "VA"

Fixed

• Grid power and solar power returning 0 due to incorrect register mapping
• Battery remaining energy returning double the correct value (wrong scale factor)
• Phantom voltage on unconfigured PV string 3

Removed

• Unused ConfigEntryNotReady import from __init__.py
• Unused REG_* constants from const.py
• pv1_today / pv2_today individual string energy sensors (not available via Modbus)
