Inverter Settings

The Inverter screen provides access to device information, diagnostics, and all configurable settings for your inverter or gateway. Sections are collapsible — tap a section header to expand it.

Overview

Field	Description
Product	Device type (e.g. Gateway, All In One, Hybrid GEN3)
Serial	Device serial number
Firmware	Installed firmware version
Status	Current inverter status (e.g. On Grid, Off Grid)
Last Updated	Timestamp of the most recent data read

Fault Log

Lists active and historical faults reported by the inverter. Faults can be reviewed and alerts cleared from here. See Fault Log for full details.

Write Log

A timestamped record of every setting written to the inverter from GivLocal. Each entry shows the register address, the value written, and the time. The log can be searched, filtered by date or register number, and exported.

Useful for verifying that changes were applied, or for diagnosing unexpected behaviour after a settings change.

Live Telemetry

Displays raw register values from the inverter in real time, grouped into categories:

• PV — solar input voltages and currents
• Grid — grid voltage, frequency, and power
• EPS — emergency power supply readings
• Temperature — inverter and battery temperature sensors

Battery Control

Setting	Description
Eco Mode	When enabled, the inverter automatically manages charge and discharge based on schedule and conditions. For most users this should stay on.
Battery Reserve	Minimum SOC the inverter will discharge to under normal operation (4–100%). Increase this to keep charge in reserve for a power cut.
Pause Start / End	Time window during which the battery is held
Pause Mode	Not Paused, Pause Charge, Pause Discharge, or Pause Charge & Discharge

Power Limits

Setting	Description
Active Power Rate	Overall inverter output as a percentage of its rated capacity (%). Reduce to cap output for export limiting or grid compliance.
Charge Power Limit	Maximum battery charge rate in watts. Setting to 0 disables battery charging entirely.
Discharge Power Limit	Maximum battery discharge rate in watts.

The maximum values available on these sliders reflect your inverter’s hardware specifications and battery configuration.

Tip

If Use Max Power for Quick Charge/Discharge is enabled in App Settings, these limits are temporarily overridden when you tap Charge Now or Discharge Now.

EMS Controls

Available on EMS devices only.

Setting	Description
Plant Charge Compensation	Fine-tune the charge target by a small offset (±5 W) to account for measurement differences between the EMS and individual inverters
Plant Discharge Compensation	Fine-tune the discharge target by a small offset (±5 W)

Clock

Displays your phone’s current time alongside the inverter’s internal clock. Tap Sync to write your phone’s time to the inverter. Keeping the inverter clock accurate matters for schedule execution.

Automatic skew detection — when the app connects, it compares the inverter clock against the phone time. If the difference exceeds two minutes, a prompt appears asking whether to sync. The prompt appears at most once per day.

Advanced

Export Power Priority — controls what the inverter prioritises when generating excess power:

Value	Behaviour
0 — PV First	Solar goes to loads before anything else
1 — Load First	Loads are satisfied first, then battery, then export
2 — Battery First	Battery is charged before exporting

Battery SOC Calibration — if your battery state of charge reading has drifted, you can run a calibration cycle here. Choose Full (charge to 100% then discharge) or Charge Only (charge to 100%), then tap Start. Tap Stop when complete. This is a slow process that can take many hours.

Real-Time Control (RTC) — enables or disables real-time control mode. Only available on supported devices and firmware versions.

Caution

Only change RTC mode if you understand its implications.

Grid Compliance

Setting	Description
EPS Mode	Enables Emergency Power Supply (off-grid backup) mode. Only appears on supported inverters.
Zero Second EPS Changeover	Enables near-instantaneous switchover to battery during an outage rather than the standard brief interruption

Caution

EPS settings affect how your system behaves during a power cut. Do not change these without understanding the impact on your installation.

Service

Restore Defaults — writes a fixed set of values directly to the inverter’s holding registers, returning operational settings to a known baseline. Useful after testing or after a quick action has left the inverter in a non-standard state.

Values written on restore:

Setting	Reset value
Eco Mode	Enabled
Charge schedule enabled	Off
Discharge schedule enabled	Off
Battery Reserve	4%
Active Power Rate	100%
Battery Pause Mode	Not Paused
Battery SOC Calibration	Reset

Power limits are reset differently by type:

Inverter type	Charge Power Limit	Discharge Power Limit
Hybrid / All-in-One / EMS	50%	50%
Gateway / AC-Coupled	100%	100%

Note

Restore Defaults clears the schedule enable flags but does not touch slot times or target SOC values stored in the Schedules tab. Your configured charge and discharge windows remain on the inverter — they are just disabled. Re-enable them from the Schedules tab when you are ready.

Corrupt slot detection — after applying defaults, the app reads back all slots. If any contain an invalid time value (a known firmware quirk where minutes is set to 60), the app automatically clears those slots and logs the action.

Restart Inverter — sends a software restart command. The inverter will briefly go offline.

Restart Hardware (Gateway systems only) — separate options to restart the Gateway, connected AIOs individually, or everything at once.

Caution

Restarting hardware interrupts monitoring and may briefly affect loads the inverter is powering.

Commissioning (Installer tier)

This section requires the Installer tier and covers settings typically configured once during installation. A confirmation prompt appears before any write is sent. This can be disabled in Settings → Diagnostics → Confirm Commissioning Writes.

Setting	Description
Grid Code	Grid compliance standard for your country/region (0–29)
Meter Type	CT clamps or energy meter (EM418/EM115)
Battery Type	Lead Acid or Lithium-ion
Battery Capacity	Total battery capacity in amp-hours
Auto Read BMS	Whether the inverter reads SOC directly from the BMS
PV Startup Voltage	Voltage at which the inverter begins accepting solar input
Grid Export Limit	Maximum export power in watts
Grid Import Current Limit	Maximum import current in amps
PV Input Mode	Independent Strings (separate MPPT per string) or Combined
CT Direction	Flip the CT clamp reading if it’s showing negative when it should be positive
Force Off Grid	Isolates the inverter from the grid — use with care

Diagnostics

Tools for troubleshooting. None of these change inverter settings.

Register Reader — read a specific register by address and slave ID. Choose Input Register (IR) or Holding Register (HR), enter the address, and tap Read. The raw value is shown immediately.

Register Dump — reads every register on the inverter and saves the result to a file. Useful when reporting a problem or comparing states before and after a change.

Plant Dump — like Register Dump, but covers all inverters in a multi-inverter plant.

Register Sweep — scans all registers and lists only those with non-zero values. A quicker way to find active or changed registers without wading through the full dump.
