Zendure SolarFlow

Omnibattery connects to Zendure SolarFlow devices through their local HTTP API. The wizard probes the device and detects the model automatically; you do not need to select a model manually.

Disable HEMS

Keep HEMS disabled in the Zendure app while Omnibattery is controlling the device. HEMS overrides manual power setpoints after a few seconds.

Connection

Enter a descriptive name, the device's local IP address and its HTTP port. The default port is 80. The device must be reachable from Home Assistant on the local network or through routing.

Field	Description	Default
Name	Name used for the battery device	—
Host IP	Local IP address of the SolarFlow	—
HTTP port	Local API port	80

The connection test reads /properties/report, verifies the device and seeds the model-specific power limits.

Supported models and power envelopes

Model	Maximum AC charge	Maximum AC discharge
SolarFlow 800 / 800 Plus / 800 Pro	1000 W	800 W
SolarFlow 1600 AC+	1600 W	1600 W
SolarFlow 2400 AC Pro / 2400 AC+	2400 W	2400 W
SolarFlow 4000 Mix AC+	4000 W	4000 W
SolarFlow 4000 Mix Pro	4000 W	4000 W

The device report remains authoritative if it announces a lower limit. The The 4000 Mix Pro exposes dual DC MPPT telemetry; the AC-coupled 1600 AC+, 2400 AC+ and 4000 Mix AC+ models do not expose DC MPPT telemetry through this connection.

Existing 2400 AC+ entries are promoted automatically when the device reports the 4000 Mix AC+ or 4000 Mix Pro product identifier. The saved user power ceilings are retained; raise them in the battery options if you want to use the larger envelope.

Zendure-specific settings

The common limits page includes charge/discharge power, maximum SOC, minimum SOC, charge hysteresis and the backup offgrid threshold. Zendure uses a minimum SOC range of 5–50% and does not use Marstek's cell-voltage taper.

Nominal capacity is optional. Enter it when you want Omnibattery to calculate stored energy and efficiency from SOC; Zendure does not provide a nominal capacity counter in its report.

Manual control

Zendure has no native force-mode or charge/discharge setpoint entities in this API. Omnibattery therefore provides software Force Mode, Set Charge Power and Set Discharge Power controls. Select the per-battery Battery Manual Control switch before using them; the controller re-applies a non-idle software setpoint on each cycle while that switch is enabled. Keep HEMS off or the Zendure app may override the command.
